Above 20 Hz that is. Somewhere near the end he states that the LLTs hit harder for the below 20Hz stuff even though the two measure about the same in that range. He does have a lot of LLT woofage in his theater though...I had this assumption also until I read "mynym's" comparison of a 15" Tuba HT compared to a 18" LLT. He states the Tuba wins hands down.

The THT would be tempting to play with if I were not at the top of a 3 floor walkup building.
