Product Description

Amazon.com Product Description

The KLH ASW12-200 subwoofer is designed to give a satisfying bass kick and enhanced low-end sound to any home theater array. A 12-inch front-firing fiber-cone woofer driven by a 200-watt amplifier means that even big rooms will be filled with explosive, deep bass sound. The designers at KLH have housed the driver in a ported composite-wood cabinet with a handsome black finish, so it will look good in any room in the house.

Adjustable phase and crossover frequency controls are included to set the subwoofer's output to match your surround speakers, giving greater clarity and stronger response. Additional features include quick-connect and low-level terminals, along with auto shutoff to cut power when no signal is present.

The KLH ASW12-200 comes with a one-year limited warranty on parts and labor.

4.0 out of 5 stars Low sonics for less, January 21, 2001

This review is from: KLH ASW12-200 12" 200-Watt Front-Firing Powered Subwoofer (Electronics)

I believe that music as recorded on any source be as accurately reproduced as possible - as it was performed. The problem is that this is not always the case, and so, we are all guilty of "tailoring" the sound to fit our preferences. Recording equipment and the equipment used to reproduce music is not always faultless. The KLH ASW 12 subwoofer is as near to faultless as is possible for $200, and is more than capable of accurately reproducing musical instruments of low sonics. This is my opinion as a musician of many years. I am pleased that I made the decision to add this subwoofer to my system, and I did so economically. However, I found that some experimenting with placing and adjusting the unit is required. My advice is to be cautious not to "add" low frequencies which are not on the source, and which make music muddy and boomy. When properly adjusted, the ASW 12 reproduces low and tight bass sounds in a large room, but don't put it in a corner on the floor. One trick is not to set the gain too high, but only at the point where the sub is silent during moderately loud passages of the music being played. If the sub is trying to reproduce frequencies at a level above its design limits, then clarity in the music will be lost. I have found that the crossover adjustment should be set at a point where the lowest frequencies of the main speakers begin to rolloff, and the sub takes over. This is its purpose after all. In adjusting the gain and crossover controls, less is more; at least in the case of the KLH ASW 12. Remember, this unit has a 200 watt amp on board. The only fault I have with this sub is the overall size which is large. Perhaps this is a design necessity. Also, for a company who should be proud of their product; the owner's manual doesn't reflect pride or much of anything, including detailed instructions which are, concise and ambiguous. Here again, you can't rely on much help from KLH engineers. A good musical ear will tell the listener where to best place the KLH 12, and how to adjust it.

2.0 out of 5 stars Poor reliability, July 1, 2003

By A Customer

This review is from: KLH ASW12-200 12" 200-Watt Front-Firing Powered Subwoofer (Electronics)

The speaker was fine while it worked. The circuitry just went out on mine, however, for the second time in just over a year of light use. I had it replaced the first time (at half of the cost of the original unit) and now plan to give up and buy something of higher quality. Quite a disappointment.

3.0 out of 5 stars Subwoofer, May 20, 2001

In the 8 months I have had this subwoofer, the base has never been a good "thump". It seems there is more amp than there is speaker. In trying to get what I was looking for, the subwoofer went out. Now I am looking for a new speaker. I always had to keep the gain and the frequency turned down to half or less than half in order for the sound not to have a splat to it. I am now looking for something that will hold up better.
