Axiom Home Page Forums General Discussion Technical Questions Ultrasonic rumble on music with EP500

Well living with it for a week now I still think I have a problem with my sub or the amp. The stand bye mode quit working completely on the sherwood so there is some kind of problem there. The thing is its in a small bedroom I should not have to turn the volume past 12 to even see the driver moving with me right next to it. And if I crank it too high it distorts with that rumbling. It should blow that little bedroom away but it doesnt at all. I have the sub on bypass and all my xovers set at 80hz on the amp. I am going to try a diff amp to see. They told me it isnt a diff design just a modification and to just turn the filter off and it is the old design whjich I dont get because I HAVE NO TRIM to adjust.
