What speakers have best bass for hip hop, and rock

I have revel studios and krell kav2250's bi amp, and I'm not that happy with the bass or soundstage. I recently heard a B&W 801N, liked it, and want to audition the new 802D. Any comments or suggestions would be greatly appreciated. I really don't know what else is out there that would be good. As you see, I am mostly into "popular" music. Thanks.
