I want to add a subwoofer into my stereo system to extend the base where my Canton Karat L 100 speakers fall off. This system will be purely for stereo music listening. I am planning on purchasing a Marantz PM7200 integrated amplifier and want to know my connection options. Are to prosessor outputs on the PM7200 volume controlled so they can feed the subwoofer and control the subs volume along with the Karat speakers? Would it be better to hook the sub to the high (speaker) level outputs on the PM7200 in parallel with the Canton Karats (stacked banana plugs going to sub and speakers) or would it be better to connect the sub to the high (speaker) level outputs on the PM7200 and then connect the Cantons to the high (speaker) level outputs on the subwoofer thus utilizing the subwoofers built in crossover? I want to know the best connection alternatives since this will affect my purchase (some subs don't have high (speaker level) outputs, some don't even have high level inputs. Thanks for helping a confused newbie. I've read all the posts concerning subwoofer connection to stereo systems and am still in the dark.
