What is phase on a subwoofer

In other words, there is no intrinsic correctness to either 0 or degrees as your final listening result. This means we are cancelling bass from your main speaker, thus reducing the overall output of bass which is obviously counterproductive. We warned you it was simple to do and easy to grasp both the importance of, and the correct method for, adjusting phase. A note; the difference may initially not seem terribly obvious. It can at first seem relatively subtle.

Just count the clicks so you recall later that you turned it down, say, two clicks. Ultra Systems. Prime Wireless. More About Speakers. Prime Wireless Speaker System. Prime Wireless SoundBase.

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. 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.

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. 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.

If you're having problems finding the perfect spot, try this method: move your couch or chair out of the way, or into another room, and put the sub in the listening position.

Yes, I know that sounds like a crazy idea, but it's just for test purposes. 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. As you move about you'll notice the bass' apparent loudness and definition changes from place to place. When you find the place that sounds the best, put the sub in that spot.

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. That location can work wonders and really improve the sound of your subwoofer. 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 have a wireless subwoofer, skip ahead two paragraphs. The Hsu Research subwoofer's rear panel pictured on the right is fairly typical. 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.

Next, turn the sub's low-pass crossover control knob to its maximum, highest numerical setting you're going to rely on your AV receiver's internal crossover control to route the mid and high frequencies to the speakers and the bass to the sub.

Turn the volume control halfway up. How long is long enough? Measure the distance between your AV receiver and sub and remember to include the distances up and down over doorways and furniture.

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. If your AV receiver has an auto speaker setup program, run the complete setup routine with the calibration microphone that came with the receiver.
