I'd recommend looking at an MTM design with 6 inch or larger woofers. A couple of 6 1/2 inch MTM's will move the air of a 10 inch woofer and still give you the midrange performance of a 2 way.
An excellent MTM is a very nice speaker. Sorry, no recommendations, I build my own stuff, but I'm sure a few people seeing this will have a couple of solid recommendations
