Have you tried some of the ported speakers in that price range,such as the B&W 805s and Wilson Arcs for instance....timing,speed and bass extension on both are excellent in the price class.

If you have tried them(with good high powered and tolerant amps),then you may find some of ATC's range to be what you're after,but as with the B&Ws,you will need a good amp to get the best out of them.
