If it's not built in by hand or here to test or for a customer, it wont be found here lol. I picked up the 12" Revo's for 280 per, and they make short work of 13W7's and are 1/2 the price, as does the 3HP composite cone 10" Proto $230 lol. When JL can figure out how to use the full excursion potential of their designs and makes them a bottomless motor geometry I will have a few. Till then, they remain mass market 2nd rate woofers to me, better than most of the mass market crap for sure, just not on par with the stuff I prefer. Original TC/AP equip has no mass produced equivalent, a 12" Neo (thick neo tall 3HP) axis will eat a critical mass UL12 for breakfast and is 1/5th the cost lol.
Brand wise, only thing I recommend is Incriminator Audio (Nick is a killer dude) Dana Audio True Bass Solutions, Original TC Sounds/AP Daber Audio, Hemp Acoustics, HiVi, Morel, Dynaudio, Jantzen, Seas, Fostex, Atomic, RD. Everything else is either full china or about to be. I liked AQ till the new line-up
DC Audio is okay too but their QC is questionable as is T3. 3 outta 6 drivers I have ordered from T3 were fked and I picked up a DC lvl 4 10 to pull TSP's they had used the wrong coil and at 1" P-P travel it bottemed out, have to pay shipping to and from for them to fix it and 35lbs from VA to NV and back is very unfriendly when I had to pay almost retail for it. Super low BL on their insanely large motors as well so all that ferrite isn't fully charged. BL on my Lvl 4 10D2 in Series was 17TM, Fs was 47Hz Qts was .42?? That makes for a nasty soundling driver even if it didnt have coil issues
