I found him through the Audyssey website as a certified installer in my town. Unfortunately, I don't know anything about this room correction stuff. But based on what people've told me, it seemed like the Diva was a better choice.
BTW, it is much cheaper to install audyssey by a certified installer than the Diva (seems like Diva takes much longer time to install).
IMHO, Audyssey and Audio Control claim that they have an excellent room correction unit on their websites. But only people can judge them who have heard both units in action.Edited by sharok - 7/29/12 at 1:14pm
