I have classic 4's biamped using an old HK reciever for a tubey top end and 2 channels from the NHT Power5 for some bottom power and I do not miss a sub at all. Im using the x2 crossover as bass management and it all works great.
NHT Classic Fours bi amped
Is anyone running these speakers, and if so, can you get away without a sub if you run a separate amp for the woofers? They claim you can, but I have never heard them this way. I'm skeptical whether on not they can actually do a subs job. If they eliminate the need for a separate sub, then I'm interested.
