Do I really need a sub?
I have my Yamaha RX-V771 feeding a front pair of Monitor Audio BR5s with BR2 rears and a BRC centre. It’s a small lounge, pretty square, and the speakers are optimally positioned. The bass from this bi-amped setup is pretty impressive already. Watching Star Trek into Darkness last night the music from the club where Scotty gets drunk was really making the floor shake.
My question is would a subwoofer really add anything substantial to this setup? Do subs only have an effect on the overall bass produced, or is the entire tonal balance of the system affected once the front speakers are not given the full spectrum to reproduce? Any advice would be appreciated.
