[QUOTE="Art Welter, post: 75854, member: 52"] Re: Horn theory questions EV 10M has a FS of 65 Hz, Xmax of only 2.8mm, EV 12L 55Hz and 3.3mm. Compare that to a decent LF horn driver, the Eminence Lab 12, with a 22Hz Fs and 13mm Xmax. Building a very large horn to try to reach 30 Hz with either driver is a waste of wood, unless you don't care for much LF output. Either EV driver can work well in a horn designed to go to the FS or a bit below, and can hit some rather amazing levels (close to 130 dB) with a few hundred watts. With a tapped horn you can cheat down quite a bit lower than the FS, but 55 Hz is almost an octave above 30 Hz. [/QUOTE]
