Take a look at 'horn' speakers, they play the loudest. As with all speakers, you need to demo them in your room, with your rig. Otherwise, you gamble with your money not to mention the WAF. If s/he knows that they first come into 'he/r' house conditionally for evaluation, half the battle is won. Of course you must read the Toole book, Sound Reproduction before making any choice. The 'room' and the speakers are a package.
