I have 2 subs-10" Eminence. We run these with a Yamaha power amp, commercial. I have never ran out of power. I have a Marchand crossover to make sure the level is right for subs and mains. The crossover is at 100 Hz.I don't have phase adjustment. These subs are where they were for 20 years. I don't know if it would sound better somewhere else. Recently I removed the crossover and ran the speakers fill range. Not as clear, less bass and transients all were not as good. Why? The subs reduce load on main amp and reduce intermodulated distortion. This causes the mids to be not as clear. I have 2 bass traps and 6 first reflection with 3 diffusion panels in rear. I finally have the system so I can walk around the room and the sound is the same, except no imaging. I could buy a couple more bass traps, don't cost much.
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?
