What a whallop that thing must put out! I realized when reading your post that your new horn with the high-power driver might generate more than 10dB greater than the old one. My thinking in my last reply to you was that with the greater power, there would also be a little more compression. But this overlooks the fact that the original driver would suffer from compression too, and maybe (probably) more than the better one.I hope all your interior trim pieces are well attached. But I'll bet they don't stay that way!
