I plan to build two single 12 cabinets. I'm looking for a relatively inexpensive ($150 or less) driver that will give me a warm low end, i.e., not weak in the 50-90 Hz range, and realatively flat above 90 Hz. I plan to tune to 45 Hz and want the -3 dB point to be at or below 45 Hz. I don't care about response above, say, 600 to 800 Hz because I plan to also build a fEARful type head case for a midrange driver. By the way, low weight is important - that's why I'm building separate 1x12's and a separate midrange enclosure. That being said, a Neo 12" driver would be nice, but not necessary. I've modeled several Eminence and Carvin drivers in WinISD and the best choice so far seems to be the Eminence Delta-12LFA. But, according to Bill Fitzmaurice, "The 12LF ... was a better than average low frequency driver when introduced, but that was over a decade ago." My questions are: 1. Why is the 12LFA at best only "better than average"? 2. Is there a better choice for my design goals?
