Two subwoofers or One?


I have a pair of Martin Logan Ascenti speakers with one Descent sub. What advantages besides having them operate in stereo would I get?

My room is 14' wide by 40' long would 2 subs. be more balanced, or should I just stick with the one sub?

Any help in this matter would help.
Thanks

Unsound, What you are referring to did happen when people summed the L and R electrically by using a Y connector at the preamp and then running one IC with a mono amp for the sub. But if you keep the two channels separated electrically and either use a woofer with two voice coils (and a two channel amp) OR mix the channels with a buffered circuit and then use a single amp and voice coil, then that won't happen.

Whether one gains more spatial effects when two separate subs interact in the room has been debated. I suppose if a low frequency signal like cannon fire was clearly located on say the left channel, you would notice it, but anything below 120 Hz isn't very directional and I think the room would tend to soften that effect. It's the mid-bass and midrange that gives directional cues, and those are being handled by the main speakers.

.
Nsgarch, I can't argue with the truth. I will say that I while most experts agree that low frequencies aren't very directional, I suspect that on some level we are aware of something askew when those frequencies harmonics appear from where they might not aught to be.
As far as subwoofers go: two are better than one. 12" woofer is better than 10" and in my case, 15" is heavenly. IMHO. warren :)
THANKS EVERYBODY FOR YOUR HELP.
WHAT IF I USE 2 SUBS, AND SET THE CROSSOVER TO 70 HZ. INSTEAD OF 40 HZ. WILL THIS WORK?

On our website there are two resources that will help you. One is a paper on speaker placement. It includes subwoofer location. The second is a paper by Todd Welti and Floyd Toole on the use of multiple subwoofers.

Here's a link to our Resource Page.
