Yeah, DJ Whalesong and the Quaaludes and their platinum album "Half Speed". Seriously, I've seen plenty of those wind tunnel builds and never once seen anybody playing anything in them that isn't either slowed down or some normal song re-mixed with test tones overlayed. Even the old school woofer test CDs don't contain much material below 35hz.
I said this already earlier in the thread, in fact I believe I told OP that that was the most important consideration is what tuning will be best for the woofer.
And most folks have no idea what frequencies are in their music or would be able to guess what a tone was if you were to play it for them. I wonder though, when you ask people what music they listen to, how many of them tell you they can't remember or don't have time to type out a few examples for you?
