What speakers have best bass for hip hop, and rock

"there's allot of bad stuff out but some is very good if you have a open mind and hungry ear".

Your ear would have to be somewhere beyond famished to find much worthwhile.

My vote goes to a pair of Klipsch Chorus II's. I own a pair that I don't use anymore but they can put out some serious SPL in the bass dept. You can probably find a used pair for under $500. I got mine from ebay years ago but I'm sure some show up on the Gon every once in awhile.

Each cabinet has 1 active 15" & 1 passive 15" along with two separate horns for Mid/Tweet

The price is fantastic. Are there many dealers where they can be auditioned?

I have yet to hear anything better than the newer series 3 or X000 series OHM Walsh speakers for this. You do need the right amp though.

If you really want to hear all the intricacies of JayZ, or 50 Cent recordings, then B&W 801 might not be resolving enough.

The bass shouldn't be too bad either
