1 large subwoofer or 2 smaller ones...?

Looking for opinions on whether to use one large subwoofer (Martin Logan Descent i) vs 2 smaller subs of the same design (ML Depth i). Cost for the 2 setups would be similar, but my room is better suited to support 1 sub than 2. Main speakers are Martin Logan Ascent's.

I used to have one REL Storm III, and now have two DIY boxes with Rythmik 12" kits. So my two subs cost the same as my previous larger one, but the two subs aren't smaller than the one. Rest of system is the same. I would agree 100% with the 2-sub route because of the smoother response and ability/flexibility 2 subs provide.

Whether you get better results with the subs playing in stereo or a summed up mono signal will generate a lot of debate. But that's a bridge you don't need to cross now.

Two subs for sure. One of my two is currently out for service and the difference is NOT subtle.

2 small ones in a stereo application ...although those frequencies may be mostly "non-directional"....you have to compromise one way or another with only 1...

a) only hook to one channel (obvious downside) or

b) combine both outputs... (they will sum..and in effect, at times, cancel each other ...or at least work against each other. Do some searches on the topic on the web.... Many out there who can explain it better than me.

BTW.... Thought I could get away with one...now, so glad I have two.

As they say in all things audio, it depends. I have two. The only real way to find out is buy two identical units at the same time with full return privilege, that means no restocking fees. Try to get a 60 day return privilege as you will find it takes awhile to find the answer. If you buy only one, you will never know if you are missing something, and that will drive you crazy, as all things audio can do.
