Revel f12 owners....

I have the infinity primus p363's and the revel f12 so I can tell you that the revels blow the infinity's away, they even sound better than the infinity beta 50's, had them too, the revels have much better drivers than the infinity's, revel uses cast aluminum baskets on all their drivers as compared to infinity's stamped sheet metal drivers, the crossover is better in the revels too, the revel uses a 1 inch dome tweeter as compared to infinity's 3/4 inch dome, most people who own the infinity's complain that infinity should have used a 1 inch dome in the speaker as the 3/4 inch tweeter they use doesn't sound that great, the cabinet is thicker on the revel and made of a higher quality board.

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.

I would give a listen to the magnepan MMG $600 MSRP, aside from deep bass response they are very detailed from top to bottom and throw a really nice 3D soundstage much better than the primus series, they lack a little in dynamics so I wouldn't recommend them for rock music.

I agree with you though, the primus speakers are hard to beat at their price, I remember people buying them new a few years ago for only $199 a pair, at that price they were a steal, there is a used pair of revel f12's on the bay for $800.

MMG's probably wouldn't sound too good on classic rock, I Have a pair of Infinity IRS epsilons and they sound incredible on the best recordings but when I want to listen to classic rock I turn to my revels.
