As said above, the center channel is mainly for voice, so if you can hear dialogue clearly already, then as most others say, get the Sub(s). Also, the center channel will in my opinion make 2 channel music sound worse. I spent plenty of time and money on a high-end HT system and 2 channel music never sounded anywhere as good as my 2 channel.
2 channel setup - Should I add a center channel or $1500 subwoofer?
Hey everyone I just bought the B&W 702 s2 as a 2-channel start to an eventual home theater, but I only have another $1500 in my budget for right now. Should I add a matching center channel that runs at $1500 or use the money for a decent sub? If so what sub would integrate well with my speakers? Would the SVS SP-4000 be a good choice?
