When the bass sound is lacking or unclear, switch the subwoofer phase. In some rooms, smooth bass response won't be all that hard to achieve, but I've heard my share of "problem" rooms where the bass always sounds boomy or muddy. Three things can affect the output of your sound system when testing your subwoofer crossover: Overlap of your large, small, and main speakers The volume output of your subwoofer and speakers The goal is to get the best balance of deep bass from the sub and still have the mid and upper bass from the speakers in equal proportions (adjust the subwoofer volume control in each new position). Adding delay to the subwoofer signal can sometimes help the subwoofer to integrate better with the loudspeakers in the room. The most common crossover frequency recommended (and the THX standard) is 80 Hz. First, you will need to set all of your speakers so that they are facing the same direction. You may have to try a few different recordings before you hear any difference, and it might help to turn up the sub's volume level for this test. The sub and speakers have to work together as a team, and ideally you should never hear the sub as a separate sound source. Your speakers' or subwoofer's user manual may offer specific guidance in this area; otherwise use the Audiophiliac's crossover recommendations: for small speakers with 2- or 3-inch woofers, try settings between 150 and 200Hz; for midsize speakers with 4- or 5-inch woofers, use 80 or 100Hz; and with large bookshelf speakers or skinny floor-standing speakers, try a 60 or 80Hz crossover. You'll be amazed just how different the bass sounds in different locations -- some will be muddy, some will sound louder, and some will reduce the bass volume. If the sub and main speakers were in phase, he'd hear a single thump when he connected the battery to the wires leading to the sub's terminals. Buying a cable a foot or two too short is a drag, and after you've opened the package you may not be able to return it for a refund or exchange. When all else fails, try placing the sub as close as possible to your couch or chair, with the sub in the "end table" position. Setting the phase control to 180 degrees reverses the polarity of the subwoofer. Merely buying a great subwoofer is no guarantee that you'll wind up with great bass. To check your sub's phase, play music with lots of bass, listen for a minute or so, and have a friend sitting by the sub flip the sub's 0/180-degree phase switch slowly back and forth. Now play music and movies with lots of bass, and take a little stroll around your room, stopping in the spots where you'd like to place the sub. Be respectful, keep it civil and stay on topic. For really small speakers or skinny sound bars, keep the sub as close as possible to the speaker(s). If you don't hear any difference between the 0 and 180-degree settings, leave the phase control in the 0 position. Yes, I know that sounds like a crazy idea, but it's just for test purposes. If you have larger speakers (with 4-inch or larger woofers), some placement experimentation may be useful; play a CD with lots of deep bass and keep repeating the track as you move the sub to all of the visually acceptable locations in your listening room. It's provided because the speakers and subwoofer sound best when they are in-phase -- meaning their woofers move in and out in sync with each other. If you need a long interconnect or RCA subwoofer cable, I recommend Blue Jeans Cable. As you move about you'll notice the bass' apparent loudness and definition changes from place to place. For specific setup instructions for Fluance subwoofers checkout our subwoofer setup video. When you find the place that sounds the best, put the sub in that spot. On some receivers you'll be presented with a wide range of subwoofer or crossover settings, from 40Hz up to as high as 250Hz. ALL RIGHTS RESERVED. But your center and surround speakers will still likely work best run as "small" speakers. Larger speakers are generally easier to match with subs; small speakers or speakers with 4-inch or smaller woofers can require more fine-tuning to get right. If you're lucky enough to have large floor-standing speakers with 8-inch or larger woofers, you may wish to run them as "large" speakers. Sets the phase of the subwoofer. A sound level meter can be a big help when setting speaker levels, but it's nearly useless for determining the sub's correct volume level. That might be all you need to do. Learn how to correctly set up your subwoofers for optimal placement and connectivity. The Hsu Research subwoofer's rear panel pictured on the right is fairly typical. If they were out of phase, he'd hear a double thump.That's with passive subwoofers, though. To non-audiophiles the maze of connectors can be intimidating, but in most instances the single-cable Sub In connection will be the easiest and best-sounding hookup method. The subwoofer crossover is a crucial part of setting your speakers to work harmoniously and avoid inconsistencies with the output. If you don't hear any difference between the 0 and 180-degree settings, leave the phase control in the 0 position. Some folks like to feel the sub working the room all the time -- and some prefer to only hear the sub's contributions with big special-effects-driven movies or dance music. “Speaker” > “Configuration” > “Subwoofer” > “Phase”, Setting the use of a center speaker and its size, Setting the use of surround speakers and their size, Setting the layout of the surround speakers, Setting the use of surround back speakers and their size, Setting the use of presence speakers and their size, Setting the layout of the presence speakers, Setting the crossover frequency of the low-frequency components, Setting the distance between each speaker and the listening position. All of the bass should appear to come from the speakers. If you're still not satisfied with the sound try using the receiver's manual speaker setup. So if you have any doubts, try turning the subwoofer's volume control up or down. © 2020 CNET, A RED VENTURES COMPANY. Setting the subwoofer volume is next. Corner placement is the de facto strategy for most people, possibly because the sub will then be out of the way and almost always produces the most bass, but corner placement may not yield the most accurate bass, or smoothest transition to the speakers. Then again, don't be surprised if the sub still doesn't sound as good as you think it should.
