Dont be fooled by size of the sub or amp. I bought a Martin logan dynamo. It has too be the smallest 10inch sub I have ever seen tipping the scales at a mere 28 lbs with a 200 watt amp and 10 in woofer. It is one of the best subs I have ever heard. Very fast, accurate, musical, and produces great bass. It does not get down to sub 20hz but its goes deep. Was very shocked when I heard it.

I agree with the Dynamo nod, it is probably my most favorite sub I have heard yet. For a 200 watt amp it rocks, I had it walking at BB. It doesn't go super deep, but you almost wouldn't know it by how powerful it sounds.
