I'm tempted to say that my 10 inch Infinity smokes your Dawg Crusher.
What impressed me was that Audessey dynamic EQ business where your bass sounds good at any volume. Oh yeah, I just remembered you playing something and I could actually feel that rumble and having it bring about the instant smile. I know about a walking issue and a rattle issue but I can't imagine how far you have to push it for that to occur. Here's the other thing. When we listened to the Sig 6's, you knew that something was off in the way of a center channel being used. To me it all sounded great. You hearing may be more discerning than mine or at least more practiced.
It all get's to be the best I've ever heard so there's not a lot of room for comparison. I have heard tcarcio's multi sub affair and it smoked my dual 10's easily. That mini fridge looking thing you use easily out does his and that's in a much bigger room to boot.
I think you need some room treatments.
I gotta go back to work.
