I currently own a set of Bose companion 3 series 2 speakers. They are great and I am happy with them except for one thing. The subwoofer has a buzzing noise unless it is turned off. It is a complete hassle. I don't understand what causes it. I am considering buying the B&W MM-1 Speakers but i know they have been out for a while. Is there any other recommendations you guys have in the up to 500.00 price range? I would prefer insane speakers without a sub. This buzzing noise keeps me awake at night i don't understand what causes it. Its more of a Humming.
