Scott, phenomenal. Thats a lot of data. I'll chew on that tomorrow as that's gonna take some time to take it all in. Two quick thoughts. The sub riser is insane, I'm giving that some serious thought. May have to get me one of those. Secondly, theres that ugly 15hz null when your running the fronts alone. Nicely done!

This does not include the LFE channel.

I'm gone the next 3 days and may not have a chance to respond.

Thats is nuts. And thats just your center. You guys with suspended floors are killing me. Thats not even fair. My Dads HT is the same. He's got crazy TR with two 21 year old Velodyne 10's. He's always been on suspended floor first with second and now with crawl spaced home.

This is subjective, but if I had to guess I'd say my riser, the way I built it, probably gives me a TR increase of 4-10x over concrete. But DD and SS have 4-6x my TR and thats measured response, not subjective.
