I wanted to chime in on the sound of the speakers as well. IMO they sound GREAT! I only have about 75 watts RMS going to them at the moment, but this weekend I started my amp rack install so I could install a new amp to power them, even with only 75 watts, they still get the sound out there, so I can only imagine what it will sound like with 250 going to them.
Also when I got mine, one grill and one crossover were damaged during shipping, I sent Ken an email and he had replacements out the door and to me in just a few days.
Only thing id recommend if you get his cans, are to use some thread lock on the 2 bolts inside the can that go to the mount that holds the clamp.
