Issue with the REV series is they are horn loaded compression drivers. So you loose surface area because there is a hole in the middle of the woofer which also reduces lows and mids. I have heard that style speaker (primarily wet sounds) and they are indeed loud, but lack mids and lows. I traditional coax with full woofer to me sounds far better and fuller. Also, most that I have heard running wet sounds seem to have troubles tuning them or powering them properly. They always seem distorted at high volumes. This tells me they are over driving their system or not filtering out the lows to allow them to operate to their potential. Something to keep in mind as you shop. My JL 7.7s and my buddy's 8.8s to me sound way cleaner and fuller and stil are very loud and price comparatively as well. No I do not have stock in JL, I am just giving you my opinion based on first hand exposure to all these models.
