I've had ML Odessey front speakers for about 10 years now as the center piece of my home theater/listening room, as well as a ML center speaker and Aerius towers in the rear. But I've been using a PSB subwoofer. I plan on upgrading my processer soon from a Lexicon MC-1 to a Classe SSP 800 and I also want to get a ML Sub. But I'm stumped on which current sub would best match the system. Or should I look for an older one? My room is fairly large, about 30 feet by 24 feet in my basement. Please give me any thoughts on which sub I should get and also any thoughts on how my ML speaker set up will work with the Classe SSP 800. Thanks.
