Re: subs playing over 100hz
a simple answer would be, you can move a lot more than arm hairs with a 40 hertz tone in a high powered setup. As long as you have everything blending in together smoothly with no distortion and your happy then forget what people say. I like the high hertz response too, back then i had a lot of it when running two JL W0s in my teen years, thought it sounded amazing but never quite loud enough for me.
Seems like you can only get this type of sound response mostly from entry level low powered subwoofers and if you wanted it louder, you'd have to run multiple.
That being said, I prefer my current setup a lot more than any other setups i've previously had, just need to add some 8 inch mids to my doors.
