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.
