I have the HK 695 speakers and although they sound great, after two weeks the bass controle starts to malfunction. The subwoofer gets way too bassy and flat sounding, and generally it just sounds bad. The bass controle just starts to not have anycontrole of the volume of the subwoofer. I sent my first set back after they started malfunctioning and got another set sent to me but after 3 weeks this pair is doing the same thing. Dell tech support says its a driver problem, but im pretty sure its not since it does it at randome times for no reason, and when i apply pressure to the bass controle it crakles and acts like it has a loos connection. I got frustrated once and hit the subwoofer and it started to function correctly, this indicates to me its the speakers and not a software oriented problem. Since this happend to two seperate sets im wondering if this is a common problem.
