Overview

7" Revelator mid/woofer features a non-resonant cone and dust cap structure, dynamic linear suspension, SD-1 magnet system, "Grasshopper" cast chassis with maximized air flow and resonance terminating mounting system. Less resonance in all structures, lower compression and higher linearity, faster termination of excess energy and higher sound pressure capability. The 18W/8531G should have an F3 of about 55Hz sealed and can get down to 33Hz vented.

Incredible. Powerful, smooth and accurate.

Reviewed by DannyBadorine on 05/15/2023

I had two of these in a sealed enclosure of 1.4 cubic feet. They punch, hammer and keep getting louder. They eat a lot of power and get really loud without distorting. I wasn't using them above 400Hz, but I did test them above that and they measure incredibly well all of the way up to 5 or 6Khz. I was having trouble getting them to go low and my F3 was around 70Hz, but I think that was because of the room problems. I will test these again with a ported enclosure soon. These are the best 7" drivers I've ever heard.
