I had the house by myself today and I got to put in some good listening. I watched some WOTW, Hurt Locker, IncredibleHulk, and some other stuff I could remember pretty well from the previous setup. I really like this sealed setup, it hits hard and goes low. The sound is great, just really clean and loud. At my normal listening levels it may be a little louder on some passages than my 2 THT/SVS setup. But on most of the passages I can feel more, (the can lights in the ceiling definitely shake more) this has to do with the full octave lower of flat output I am getting. As I was listening to the above movies, I had speclab running so I could see what I was hearing, and really missing before.
I really like this setup, and for the price it cannot be beat. If i knew the wife wouldn't kill me I WOULD buy 8 more, and have 16 of these babys shaking the house down. For the price of these, I am pretty sure this can not be beaten.
I was fooling around and took some more THD graphs, didn't want to push the drivers to much harder (but I think I could have).
