That 105 dB is peak level, which not even occurs in all movies. Most speakers will distort a lot at that SPL and that's what is unpleasant, not the loudness per se.
I knew that , added the word "peak" in my post.
I have heard systems that produce 110 dB+ with <1 % distortion (my current system will not) and over about 100 dB it starts to get painfully loud to me, distorted or not. Distortion usually makes it worse, natch.
To the OP: Why not call or email Jim Salk?
