[QUOTE="helotaxi, post: 2434767, member: 550915"] The Vb given by a formula is determined by the alignment that the formula is for ie Butterworth, Chebysev, etc. and will generally give you a relatively flat response. What most people consider the "best" box volume on this forum is the one that gets the loudest with acceptable non-linearity. Many manufaturers know that that is what their customers are looking for as well, and spec their enclosures accordingly. The man. also has to account for the wingnuts out there that will try to run way more than rated power to the sub or just otherwise generally abuse it, and spec an enclosure that won't have nasty cone control characteristics that would lead to warranty claims. BTW, you messed up something in your calc on the last equation. I got 22.8" which is the same thing that WinISD gave me which is the same as the Kicker number with a different end correction. You misplaced a decimal somewhere. Your number before end correction is off by two decimal places. [/QUOTE]
