I read that the newer model primus 363 has a thicker and better braced cabinet than the primus 362, Harman's goal was to correct the lively cabinet when they replaced the p362 with the p363, my p363's cabinets measure 3/4 of an inch thick, I'm driving my revel f12's and the p363's on a forte 4a 50 wpc of pure class A amplifier and i can honestly say that the revels beat the p363's hands down, if you compare the two speakers in the same room using the same equipment as I did you will see that revel is a much better sounding speaker, it's not even close especially when you crank them up, the revels have an In-room response of ±1.0dB from 58Hz to 18kHz, that's damb good.
