Hi, I have recently purchased a Denon a/v receiver avr1604 together with 6 gale satellites and gale subwoofer. The sub is connected via coax as it is active. I would like to use my Bose speakers for day to day Hi-Fi audio by switching off speaker A and using speaker B output on amp using direct mode. I have the facility to turn off sub through amp (as it seems to work in both A and B modes) but does that mean I will not hear anything under 80hz on my bose due to setup in home cinema mode. Any ideas????
