ok so i got something simialar to this as a gift minus the center speaker http://www.bose.com/controller?url=/shop_online/home_theater/home_theater_speakers/acoustimass_10/index.jsp now here is my question i have these speakers hooked up to my receiver instead of the acoustimass module. and id like to use the acoustimass module as my subwoofer. but im missing the system input cable do you think i can still use it as a subwoofer if i get it the cable even though the other speakers are connected to the receiver? and if not do you know of any good subwoofers that are compatible with my speakers? thanks in advance
