The XTR25s do have bass . . . but they're nothing special in this department . . . actually, IMO the big Mac line-arrays are nothing special, period. The other thing is that they're designed for big amps, and you probably need double the power of your MC252 to really wake them up.
I feel that the McIntosh speakers in general are well-made and competently executed, and reasonably priced considering this . . . but rather underwhelming from a sound standpoint. But some people really like them, and they will last a very long time, and hold their value well if you buy a pair used, and then get rid of them later. Instead of the XRT25s, I'd probably point you toward some of the coffin-shaped ones with the double 10"s (LS350s? 360s?) . . . much less hassle for shipment, setup, etc. and WAY less fallic in your living room.
