Absolutely the loudest bass I've ever heard above the 90hz range.

Couldn't drop bottom even with a ton of bass boost.

Not enough deep bass. I ran 3 of these in parallel with 200w RMS power to each in a triple-sub box and there just wasn't any deep bass even with about 20db of bass boost. I recommend spending a few extra bucks and going with an Orion.

10" Orion XTRPRO DVC. I listened to just one of these with only 100w of power and it simply blew 3 Stealths outta the water.
