Well, I pulled the trigger on a svs sb2000 pro\nTHEN I ran their recommended subwoofer app for my Sony’s. They suggested the1000 series. I did read somewhere there is no such thing as too much bass! Here we go head first into the so called rabbit hole. I’d like to thank everyone for the responses and comments once again. I value these informative forums !\nchris\n\nI honestly believe that the SVS Merlin app mainly uses the cost of the speakers to figure out which of their subs to recommend!\nHowever, I believe that the recommendation of what crossover frequency to use is a worthwhile starting point!
