I have the kicker compvr 8" in mine. It sounds really good.
I have a good amount of base, but its not in any way overkill, but its plenty, guaranteed. It sounds good. I got my stealthbox with the sound deadening material, also the polyfill, but I dont remember if it's in there or not. I think it's exactly what you're looking for.
You can have mine for 120 shipped, the box is perfect the sub needs a trim ring, but is tight and accurate. its an MBQuart RWE202, PM if interested.
