One sub is fine, two are always better. More is better in the case of subs. As others have said, multiples really can better fill out the sound stage and give a really full and balanced experience. One huge fallacy is that subs are for movies and not music. That is an opinion that is completely baseless, proven wrong consistently, and only held by insane "2-channel only" types and possibly deaf sheep herders.
Your experience of moving to two subs
Hi all, I have a 2.1 system with the sub sounding best in the center between the loudspeakers. My speakers have substantial, deep, and detailed bass for their size and with the SS amp I’ve chosen. Thus, the sub’s optimal crossover setting is only at about 28hz. I have plenty of bass amplitude going on -- don’t need "more" bass.
I’m wondering about soundstage effects of having two subs on the outsides of my speakers, though. Having my sub in the center does result in some apparent compression of the low frequencies towards the low-center area. The L and R channels from my preamp are combined at my sub. I know some people may disagree and think that the source of frequencies below 60hz can’t be located by human hearing, but my experience tells me differently.
Does anyone have an opinion on the benefits of 2 subs vs only 1 when there’s no need for more bass oompf?
