Two subwoofers or One?

Nsgarch, I'm not familiar with this particular sub, so I must bow to your experience. It might be worth mentioning that it has been suggested that due to the summing of channels of stereo (i.e. not a dedicated sub woofer channel) signals to mono that it is actually possible to deplete information.

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?
