Ive heard it a few places, that long play with class d power isnt good for your tweets, and they good for fullrange drivers and subwoofers, but I know people running class d amps powering 3 way setups with no problems...
Now I have to say though... The Crowns do sound better than any other class d amp I ever heard.... so I wouldnt suggest just any class d, them crowns are special, I dont know what it is, but I have heard Pyle, crest, sanway, protech, and Behringer and none of them sounded like the crowns...
