I think ED's AV series has the softest spider I have ever used period lol, and how can you put sq and 70hz in the same sentance? You want a driver thats gonna play high freq. look for something with min xmax and a smaller mag like your old school orions or a kicker cvx. You want something to play that high so thier you go go grab a kicker in thier prefab and your golden. I think you just used to all the MTX, KICKER, PIONEER best buy circuit city subs in thier prefab boxs thats what it sounds like to me. I dunno anybody else feel that way when he describes what hes looking for in a woofer? You might wanna think about what you want out of a subwoofer because I can make a list of everthing I own and 90% of them I never crossed over 60hz. That or make the rest of your system competent to keep up with your woofer. You should adressed your midbass first before the subwoofer for the spectrum you wanna play.
Uhhh - stop judging me on what I've used. FWIW, I've NEVER used a pre-fab's box, and the only Best Buy subs I've owned were RF HE2's, and a Pioneer 304C when they were the big forum boner years ago (worked at BB in '01, so employee discount was stupid low). I've used ALOT of drivers, and alot of nice drivers at that (I added them up the other night, over 50 from what I can remember at least).
And you keep missing the fact that I've never had this problem with other drivers, and that I am NOT THE ONLY PERSON who has experienced this with these drivers. I'm not looking for much in a subwoofer. I want something that will punch me in the chest with some drummin bass, or when I throw in System of a Down, etc. You couldn't even hear the AV on Chop Suey. I've had plenty of other setups that would do that.
Lets see how many of the drivers I've owned I can remember (in no particular order):
JL 10W0 in multiple VC varieties (at least 9)
JL 12W0-12 (3)
Holywood Excursion 12's (2)
Kicker Solobaric (round) 8" (1)
Kicker Solobaric (round) 10" (1)

Kicker Comp VR 12 (2)
