[QUOTE="Kyle_Keating, post: 4439667, member: 582385"] makes no differences. take any response from any speaker and put it in a car and you can sum the transfer functions up. The car has its discrete behaviors as does the speaker and the result is the sum. Every engineer i know measures speakers in half-space anechoic rooms or for a reason. Sure... room measurements are vital for final response, but thats more important to the EQ correction and placement. I'm pretty sure 250Tm would fall all rapidly above 200Hz, and PR's have nothing to do with the upper end response. You can't make any woofer flat in a half space measurements unless it is flat or you EQ it that way. In fact many woofers won't measure flat above 100Hz. Are you trying to tell me inductance only becomes apparent in a car? In fact, here you go, a perfect counter example!
