That is good news...thank you John. I can easily adjust the frequency crossover on the subwoofer's amp. It is quite sophisticated for its time ('79). Another question I have is the application of two sub's to my main entertainment medium...music, and more specifically, as you know John, classical. I would rarely use the system for movies, although once I set up a 5.1 or 5.2 system I may be tempted to watch movies with the system. I am guessing that having two sub's would be less of a necessity for music than for movies, and for now I could not place the sub's properly for the best effect, and they would not match each other as pieces of furniture. If you could comment on that it would help me to decide what to do. Thanks
