What is under $5k speaker with best bass slam?

Let's forget everything else. The bass should not necessarily go deep down to whale's voice territory.

Simply, what speaker <$5k has best bass slam?
Define bass slam? I don't know. Something I can feel with my body. Thump, slam, shockwave, etc.

Accompanied electronics? I don't know. Let's just talk about the speaker's potential.

Thanks

Doug
