Small bookshelfs that reach 42 hz

I just about worked out what speakers to buy for the living room when the wife changed her mind from floor standers to stand mount speakers. She saw a set of B&W 805's on their dedicated stands and that was it.

Not wanting to cave in for pure aesthetics, I need to know what else to consider for a small (16" or less tall) bookshelf speaker that will allow me to reach the bottom range of a bass guitar with solidity. Please no speakers that do 50 or 60 hz and then crap out; that won't fit the bill. Price is anything up to $3000 new with stands. Nice looking matching stands are a major plus as this is the living room.

Since I haven't bought the amp yet don't worry about synergy but if you have suitable integrated recommendations that won't be above $1500 or so used I'm all ears. Many thanks.
