This effect is called the Bass Room Response of the room. And this should start you thinking, "How do I get the Bass audio into it?". The Rockville RPG15 offers a great sound quality in its simply amazing output. Get up to around 150 Hz, on the other hand, and the wavelength is now under 8 feet -- smaller than the room's dimensions. I’m here to provide informative articles, product reviews, and buying guides to help you. There are some things to consider regarding the shape of the room and how the speakers will interact with boundaries, such as the walls, the ceiling, and the floor.You want to get the best speakers your budget will allow. And we know we have to compare those candidates against what our gear can actually handle. Here is my dilemma. These form in the room, at the various Bass frequencies, because the wavelengths of those Bass frequencies are bigger than the dimensions of the room. Ideally, the crossover point will be the point when the two filters that make up the crossover intersect at -3dB. Visit my About page to read about who I am and what I do. And in between, they SHARE the job of reproducing the audio! OK, if you've followed me so far, you should now be convinced you need at least one Subwoofer in your Home Theater setup (maybe MORE than one) -- budget and physical space allowing, of course. Typically, a low-pass crossover is anywhere from 40Hz and could go up to 60Hz to 100Hz. Where the different Standing Waves happen to match up you get "Resonance Peaks" -- a boost in level of that Bass frequency. And THAT means you want to know that your regular speakers are CAPABLE of producing good audio all the way down to 40 Hz! Fortunately, Crossover processors let you specify which Bass frequency range you want steered to the Subwoofer. The Subwoofer then receives the COMBO of all this Steered Bass -- i.e., from all the speakers -- in addition to the special Bass found in the LFE channel. 12dB, you'll recall from my discussion of Balancing Speaker Volume Trims with an SPL Meter is about a factor of 4 in perceived volume. This includes almost all of the lowest Bass notes from musical instruments. even MORE to get a Musical design which also has Bass extension that low. PA Management does the same thing as a crossover, but it has additional features which is why it "manages your PA." These features will vary depending on the hardware you get, but it can include feedback reduction, limiters, and EQ in addition to being a crossover. As with many such complicated things, there's always a place to begin! There are slight differences with the features of each unit, so my recommendation is to look for durability and extra features of these to help make your purchase. First, they want their Subwoofers to be LOUD. My HSU Research speakers are rated down to 60 Hz. (Which also means they need to be plugged in to wall power.). The Dynamic Subwoofers are capable of much higher output for their size, but they aren't all that accurate. Crossover settings are device specific as others have said but I will add not just in regard to corner frequency but also in terms of the filter type and slope/order. But there's an alternative. Now compare that to the normal speakers in your Home Theater. If everything is working RIGHT that sweep tone will appear to have constant Volume from end to end across the frequencies (except for the very lowest Bass frequencies which will drop off because they can not be heard). The result isn't satisfactory because of the reported suckout around 80/90 Hz. What speaker crossover frequency are you using for your home theater? The highest frequency a subwoofer is capable of handling is the highest frequency you should use for the crossover settings. Why? We recommend settings to a higher frequency than the crossover frequency when small speakers are used. This is the "pressurization" of the room I've alluded to several times And the different dimensions of the room --its height, width, and depth -- result in DIFFERENT Standing Waves. All three KS Series Active Subwoofers feature powerful DSP, which allow you to adjust a number of useful parameters. Given the lowest frequency response of your speakers and crossover options your receiver offers, I'd say the ideal crossover point would be 150hz. From my post on Calibration Discs, you'll recall that multi-channel audio tracks frequently (but not always) include a Low Frequency Effects (LFE) channel. This goes back to the concept of Bass frequencies "pressurizing" the entire volume of space in the listening room. 2-way speakers use 2 speakers on each channel and a crossover to divide the audio frequencies reproduced between the two. I picked up a Behringer (I know) crossover which has a number of different controls on it. Choosing the most appropriate crossover frequency is complicated by the fact that the point to choose depends on the crossover that is built into the sub. The Subwoofer should ALSO be handling the lowest frequencies of this audio, as well, so that your regular speakers are not challenged with trying to reproduce it! I.e., they couple to the room differently and produce different Standing Waves. If you do not need mids as you only have high and low speakers, each unit will still work for your rig by not using the mid outputs. A Small speaker will be processed for Crossover. But in addition, all the REGULAR speaker channels can also carry Bass -- with no limit on how low their frequencies can go. However, there are common frequency ranges that will work well in many cases. Crossovers take a signal from your mixer that is a left and right channel, and separates them so you can separate signals to different speakers based upon frequencies. For discussion, let's say, perhaps, 60 Hz at the low end up to 100 Hz at the high end. So the LOWER limit for the Crossover Frequency would be TWICE the bottom end of your regular speakers. In addition to its low frequency specification, your Subwoofer likely also comes with a high frequency specification. So if you have a Crossover which begins at 80 Hz, and takes effect at a rate of -12dB per octave, that means the audio going to the regular speaker will be reduced four-fold by the time you get down to 40 Hz. The best improvement will come by adding a subwoofer. In my experience, it's best to set the low crossover point below the vocal frequency range and set the high crossover point no lower than 2.5kHz. Crossover points and Order. And that means you hear it as directional audio. So you set your Crossover at 60 Hz. And those different Standing Waves *INTERACT*! AND the audio from the Subwoofer will start to be localizable! Indeed some of those speakers are likely on the opposite side of the room! That thud you feel in your gut from a really deep effects sound, or perhaps from the lowest pedal notes of a pipe organ, are found down here! The bulk of the energy in "big" movie sound effects -- things like explosions -- comes in around 50 Hz. At the low frequency end, suppose you have speakers rated down to 30 Hz. I guess experimentation is in order to determine if dialog is improved by adjusting the center channel speaker equalizer settings in the 1-4 kHz range; AND, then playing with the crossover frequency of the center channel speaker to see if increasing the crossover to, say, 120 Hz helps the dialog clarity. We've already talked about ONE problem with that. My question is: Should I stick with the subwoofer's listed crossover frequency of 80 Hz when running sound for a rock band at a small outdoor venue? In my experience, it's best to set the low crossover point below the vocal frequency range and set the high crossover point no lower than 2.5kHz. In other words, the speakers are going to play from this frequency and up and the subwoofer is going to take over every frequency below that point. Now you can fine tune the signal being sent to each speaker by sweeping the crossover points until you find the perfect sonic fit. The result is what's called a "Hole" in the Crossover. So plan accordingly. Or all the way up to 150 Hz? A good Rule of Thumb is you don't want your Crossover to be higher than 100 Hz. Suffice it to say filtering which works like a switch -- a so-called "Brick Wall" filter -- will do damage to the audio. A crossover unit takes the incoming audio spectrum signal, everything from 20 Hz to 20,000 Hz and splits it into two or more bands. Again, this can be done because each of them is trying to pressurize that same room rather than producing "localizable" sound. These Crossovers and PA Management devices are the most popular on the market currently. The ".1" in "5.1" or "7.1" tracks, for example. If they are rated down to 30 Hz, the Crossover Frequency should be no lower than 60 Hz. The default crossover frequency is "80Hz". That being said, make sure that you have the outputs you need for your speakers. The Crossover is steering higher frequencies away from the regular speaker, but the Subwoofer is not able to reproduce those frequencies. Wavelength also works as you move away from the baffle so if the crossover frequency is set at 3000Hz and the drivers are placed further apart you will get lobeing if the midrange and tweeter drivers are more than 4.5 inches apart. That is to say, at 80 Hz and above, the regular speaker is carrying the audio. Speakers that can handle the full optimal range are referred to as "full range". Its actual frequency response is 25hz to 150hz. If you have got them installed in the car for your already decent speakers, then setting the crossover frequencies is an even better option to get the most out of it. The best crossover frequencies for this setup will be: Sub: Set the low-pass filter to 80 Hz (with a slope of 12/24 dB) Rear coaxial drivers: Set the high-pass filter to 80 Hz (with a slope of 12/24 dB) Need anything? Both of these types of hardware do some of the same things, but have a few minor differences. Bass Control computes the best possible results for the crossover frequency that is assigned by default but the user has to choose it... so that some experimentation is possible and in some cases necessary. Well what happens is that the natural reflections of the audio set up what are called "Standing Waves" of sound for each frequency. Console Main Outputs > Graphic EQs > Crossover. Firstly, on most ecommerce websites, they mention another option called PA management. Meaning you may have to step up to a larger, more expensive model to handle the size of your listening room. Visit my About page to read about who I am and what I do. You can use my Contact page to send a message anytime. So for example, are the main speakers really good down to 50 Hz or lower? And the natural averaging effect of all this can be a big help in reducing Resonance Peaks and Cancellation Nulls. Plug the main outputs of your console into the GEQ, then into the inputs of the crossover. Making changes and measuring with an active crossover or digital crossover is easy and painless. The telephone system operates between these 2 points. An adjustable crossover frequency can be a real bonus for tuning your rig. The best crossover points for our ears do not line up with the physics of speakers. Or, of course, you could upgrade to better speakers! That says the Crossover should be no lower than 160 Hz! A Weighted SPL is generally a good indicator for noise-induced hearing loss, although extremely high levels of low frequency energy can be damaging, so if a mix has a high C-A value, that is a good indicator that additional attention should be paid to LF exposure. If you try to push things too far -- say setting the Crossover at 50Hz in this example, trying to take a little more advantage of the "down to 30 Hz" goodness of your regular speakers -- you may bypass the low-end protection in the Crossover and send 25 Hz audio (or even lower) to that Subwoofer! Low-Pass Crossover is the frequency where your subwoofers will start working to reach deep notes that aren’t possible for the speakers that we have today. Crossover is simply the task of taking a single stream of audio and sending higher frequencies to one speaker and lower frequencies to another. This is a TOUGH test, and you are unlikely to get a perfect result without going into more effort in configuring your Bass Management and dealing with Room Response issues. A typical Crossover implementation will roll into effect at a rate of, "-12dB per octave". Some speaker makers also sell "satellite" Subwoofers, which are separate units intended to be attached to a single speaker, each -- and thus functioning AS IF a Subwoofer was built into each such single speaker. Sending a full-range signal to all speakers within the system, regardless of each speaker’s design, can be problematic. The audio going to the regular speaker drops even more below 40 Hz, but by the time you are -12dB down, you can pretty much ignore the audio coming out of the regular speaker. The thing to know is, the choice here has NOTHING TO DO with the physical size of your speakers! What if my regular speakers don't go low enough? We can be contacted through our contact us page found here. So we know what THAT sounds like. But what's more, it's also possible your Subwoofer is not even CAPABLE of reproducing frequencies as high as 160 Hz! Why? What if my SUBWOOFER doesn't go HIGH enough? ← "The Hunchback of Notre Dame" (1923) on Blu-ray -- A Tale of Old Hollywood! This audio doesn't vanish, of course: THAT'S the audio that's getting steered to the Subwoofer! First, this keeps the Bass safely non-localizable. But take heart. It's just that the frequencies BELOW 30 Hz are more "felt" than "heard". Frequency response measurement of main speakers taken with XTZ Room Analyzer II Standard – the 25Hz and 50Hz points on the rolloff slope have been annotated. This means at no additional cost to you, I get paid if you click through and make a purchase). Since they are smaller, they are also often less expensive. There are technical reasons for this we need not go into here. Now, to perfectly match your KS active subwoofer with your top active loudspeakers, you need to choose a suitable crossover frequency (80 or 100 Hz) – and apply the correct setting to both subwoofer and top … It is what the room is DOING to that output! Such Subwoofers may be perfectly adequate for folks looking mostly to handle Bass effects in action movies -- explosions and such. At the crossover point, power to each speaker is reduced -3dB (1/2) so total sound energy is 1. Much of the visceral excitement of Home Theater -- whether for movies or music -- comes from the proper rendering of Bass frequencies. My HSU Research speakers are rated down to 60 Hz. The more expensive (and usually larger) Subwoofers can extend that low end down to, say 15Hz. The low‑pass filter only allows signals below a certain frequency (for example, below 2kHz) through to drive the mid‑range driver/woofer of a two‑way speaker system. As a rule of thumb, the lower the subwoofer’s crossover is set, the better. Indeed, Crossover processing systems (and better Subwoofer designs) include protection to keep from sending TOO LOW frequency audio to the Subwoofer. And one important consequence of that is the Bass appears to be coming "from everywhere", as opposed to coming from the location of any given speaker. And that might be only, say, 120 Hz! If they are rated down to 50 Hz, the Crossover Frequency should be no lower than 100 Hz. When I listen to music, they sound pretty similar. Crossovers are devices that split your signal in two — low frequencies go to the subs and everything else goes to the mains. All Rights Reserved. they may be rated only down to 80 Hz. Instead the Crossover rolls into effect GRADUALLY -- over a range of frequencies. Its Subwoofer Crossover test track sweeps a test tone up and down across the Bass frequencies. So you'll have a Subwoofer built into each such speaker, plus another, stand alone Subwoofer for LFE.). Should I set the subwoofer crossover at or near 60 Hz? Bass Control computes the best possible results for the crossover frequency that is assigned by default but the user has to choose it... so that some experimentation is possible and in some cases necessary. You generally want your crossover set to where your speakers start to roll off—for example, my speakers can’t go much lower than 80Hz, so my subwoofer’s crossover is set to about 80. Both the low pass filter and the high pass filter have a cutoff frequency of 80 Hz. I am connected with an LFE cable, so I need to set the response on my receiver. Welcome to Sound Certified! A typical value for a 2-way crossover frequency is 2000-3000 Hz. At least, it can do so if you make sure to only send frequencies to the Subwoofer which WORK THAT WAY! To figure that, you must first understand the Crossover doesn't work like a simple switch -- with all the frequencies going to just one speaker or just to the other speaker. If you know your speaker’s frequency range, set the crossover point roughly 10 Hz above the lowest frequency your speakers can handle cleanly; The most common crossover frequency recommended (and the THX standard) is 80 Hz. There ARE other ways of implementing Crossover, but we'll focus on this typical way. But Second, they want their Subwoofers to be ACCURATE -- to produce Bass of high quality. I'll have more to say about Bass Management and Room Response in future posts, but as I said up top: The road to awesome Bass begins here! At the high frequency end of that sweep, the audio will come entirely from those speakers. Since a sound signal source, be it recorded music from a CD player or a live band's mix from an audio console, has all of the low, mid and high frequencies combined, a crossover circuit is used to split the audio signal into separate frequency bands that can be separately routed to loudspeakers, tweeters or horns optimized for those frequency bands. Again, it is NOT an issue with the audio output quality of any of the speakers, or the Subwoofer. A typical Crossover Frequency would be 80 Hz. Let's take a look at the differences between crossovers and PA management: Crossovers take a signal from your mixer that is a left and right channel, and separates them so you can separate signals to different speakers based upon frequencies. Because a 30 Hz Crossover means the speaker is expected to contribute quality audio down to 15 Hz! Keep in mind, this has to be done for EACH speaker channel. Think about home stereo units with midrange speakers, tweeters, and subwoofers. Unfortunately, setting things up to ACHIEVE awesome Bass is complicated -- almost to the point of being a Black Art! C-A also plays a role in sound exposure and noise pollution applications. All rights reserved. The other night at a gig during the set break while ipod music was playing thru the PA I had a tweak of the crossover … There's no set definition of what constitutes Bass frequencies, but for purpose of discussion lets focus on frequencies below 150 Hz. As we've just discussed, if you do happen to have a decent Subwoofer, you should be using it to support the low Bass in *ALL* your speakers -- even speakers you have purchased which are marketed as "full range". So, if you DO have a range of Crossover Frequency candidates (after thinking through the upper and lower limit considerations described above), one of the best ways to choose between them is to pick the Crossover Frequency which MINIMIZES the inherent, Bass Room Response issues in your listening room! Live Sound Reinforcement ... (To calculate how long an audio wave is, divide the speed of sound—1,130 ft./second—by the frequency. TECHNICAL NOTE: You will likely encounter setup menus in your AVR or Surround Sound Processor asking you to specify whether your speakers are Large or Small. Crossovers. This will ensure a smooth frequency response when the drivers are combined. Most mid-priced full-range loudspeaker cabinets have a passive crossover built into them (and some amplifiers, including our own d&b audiotechnik D12s, also incorporate crossover functions). Subwoofer designs are optimized for Bass, and that means they are not going to do a good job handling higher frequencies of audio. Many car audio stereo receivers on the market feature an integrated and user-adjustable crossover system, designed to route certain sound frequency ranges to specific speakers connected directly to the head unit, or through low-level outputs designated for external audio … I’m here to provide informative articles, product reviews, and buying guides to help you. Without getting too technical, I want to make a key point now, which will, I hope, be intuitively obvious to you given the explanation above. And at these Bass frequencies, even INCHES make a significant difference in how a Bass speaker couples to the room! However, folks who have invested good money in regular speakers, don't want the low end of those speaker channels compromised by inaccurate Bass reproduction! Use whichever controls you feel most comfortable with. If you do, then the content below the crossover frequency you set will be sent to the front L and R. But, if all 5 of your speakers are identical then there is no benefit in doing that. TECHNICAL NOTE: There's preliminary setup you need to do prior to trying this test, of course. The lowest frequencies you'll "hear" will be around 30 Hz. Instead, I want to focus on the contribution a good choice of Crossover Frequency can make in this effort! Here's a link to a handy table from JdB Sound Acoustics listing the Sound Wave Lengths for various frequencies of interest -- along with the frequency ranges of voices, pianos, organs, and guitars for comparison. Positioning the speaker closer to a wall enhances reflections off that wall. When looking for the best audio crossover for your live sound rig, there is a few things to consider. Crossovers and PA Management hardware devices will work with any speakers. I just upgraded to a bigger subwoofer, a JBL ES250P rated at 400 watts RMS and 700 watts peak power. For example, set to "250Hz" when the frequency range of the speakers is 250Hz - 20Hz. It gives me the option between 80hz, 90hz, 100hz and 150hz. This a good low-pass frequency that ensures the subwoofer bass is prioritized without including any midrange sounds. From the speed of sound, and the number of cycles per second (Hz) for a given sound, we can calculate the distance spanned by just one such cycle -- its "wavelength". Because your Subwoofer(s) and your regular speakers are, themselves, located in different spots in the room. A good starting place is with the high-pass filters on the front and rear channels set at 100 Hz, and the subwoofer channel's low-pass filter also set at 100 Hz. Other features of crossover units In addition to frequency separation, crossover units can have other functions. My Pa consists of Tapco thump tops and Wharfedale SVP15PB subs.I have had my crossover set at 120hz since forever and always thought it sounded pretty good. Picture in your mind the dimensions of your Home Theater viewing room: Front to Back, Side to Side, and Floor to Ceiling. Crossover frequency. For subwoofers: the recommended crossover frequency is 80 Hz (low pass). Because the Subwoofer can be physically damaged if it is forced to reproduce frequencies below what it can handle -- typically due to the cone being asked to travel too far, called "bottoming out". For 100 Hz audio, that's just a little over 11 feet! The usual workaround is to set a lower, compromise Crossover -- one that asks the regular speakers to go a little lower than they can handle, but also gets closer to the high frequency limit of the Subwoofer. I am not really sure whether I … Then you really WILL have a problem due to the difference in physical locations of the Subwoofer and each speaker. If you find yourself still wondering what the best audio crossover is or have any other recording questions at all, we are always there to help! The range of frequencies a speaker will reproduce (lowest to highest) is in many cases limited. From 100 Hz at the high end down to twice the low frequency limit of the main speakers at the low end. If these are the speakers you have to work with, then, of course, this is a problem you will have to live with. Indeed, your regular speakers already include their own, internal Crossover electronics to split the audio among their various driver elements: Tweeter, Mid-range, and Woofer for example. In particular, they'd like to use a Subwoofer that's physically smaller but still capable of putting out enough output to work well in their listening room. And that means you need both size AND power in the speaker doing the huffing! You'll see, by the way, that the 80 Hz Crossover Frequency I described as "typical" towards the top of this discussion is right about in the middle of the likely range. If the width and depth of the room are different, positions close to the rear wall (near the TV screen) will couple differently than positions close to a side wall. The numbers below highlight general guidelines for speaker/subwoofer crossover frequencies Limited range speakers are far more common than full range units. If you have got a cheap speaker, which does not sound pretty well or fascinating, at least to you, then modifying your crossovers could help your car audio system sound better. And with Bass audio, that means understanding why you need to include a Subwoofer in your speaker configuration, and learning how to select a Crossover Frequency to drive it. At 40 Hz and below, the Subwoofer is carrying the audio. Setting a crossover point in the middle of the vocal range can mess up the vocal sound, especially if you use radically different compression settings on each side of the crossover frequency. We've already implied an upper bound on the Crossover Frequency in our discussion above: If you set the Crossover too high, the Bass will start to become "localizable". But again, expect to have to go up in size (and price!) But bass doesn't stop there! And most of us have -- alas! Among other things, this keeps them from hopping around as that cone moves! Sound system distortion between these points can easily be heard and therefore the worst position to cross speakers over, but we have no choice. Below is a wiring diagram example to give a visual of how Crossover and PA Management is connected: You do not need to worry about compatibility. For the mid/woofer crossover there are 4 octaves between 200-3.2k Hz, 200-400-800-1600-3200. Where they are exactly opposite of matching up you get "Cancellation Nulls" -- a loss of level of that Bass frequency. The differences between studio engineering and live sound are like the differences between porn and sex. Home Theater Subwoofers have cone diameters in the range roughly 10-18 inches, and, equally important, they have power amps built in, dedicated solely to moving that big cone. If you think about that, some problems should immediately jump to mind! But second -- and again refer to that table linked above -- this keeps the low frequency end of male dialog from being sent to the Subwoofer! Mixing live sound is one of the most fun yet challenging aspects of music, and the ability to mix both in the studio and live makes a good audio engineer in high demand. (If you DO have speakers which plug in to wall power, and have driver elements specifically designed and amplified for Bass (at VOLUME), then what you've got your hands on is a speaker with a Subwoofer built into the same cabinet! Copyright ©2018-2021 Bob Pariseau. Subwoofers also differ in how LOW they can go in frequency. Crossover. So suppose you think through all this and discover you actually DO have a range of candidates to choose between? I have 5 speakers with a frequency response from 120hz-23,000hz. (Or low enough for that matter!). But it is also a sensitive enough test you may very well hear significant differences in the amount of Volume variation which happens across that frequency sweep for the different Crossover Frequencies! Even taking into consideration these tools are designed to be conservative (after all, they'd really like you to pay for a bigger, more expensive model), the size of Subwoofer you'll find recommended for typical listening rooms can be daunting. And THIS is where we start to run into the REAL complications of Bass Management! 100 Hz sounds … Copyright 2018 BlackSkye Media LLC. Audio, Video, and Home Theater Consulting.
