Sorry colesy
I really didn't mean to recommend that you get a new sub. I don't even know what you have! I think that would be a last resort kind of thing anyway.

I am curious - where did you read about those sub settings you mentioned. It doesn't pass MY logic test to set the sub's amp all the way up and turn down the receiver's sub output really really low. As I recall, many receivers don't even have that capability - at least the ones I am familiar with.
