I know it's been discontinued, and I'm desperately trying to find someone who still has one. I've had zero success finding any retailers that still have them. I don't really care whether it's the 12TW5-4 (4 ohm) or the 12TW5-3 (3 ohm). I have a very specific need for the shallow mounting depth and minimal internal air volume, but the box I have is for a 12 (which is why I can't spring for the 13TW5). I haven't been happy with the other shallow mount subs on the market, and know that the JL can really generate some power. If you have one and want to sell it, or know where I can find one, PLEASE let me know!
