I think I need a recone kit so contacted Fi and lanzar, I have the opti1535d, 1600rms and mine is 8 layer flatwind.
when I contacted lanzar they gave me a number to get the parts, 800-444-5671 x325 .
but I would prefer to get the measurements and get the Fi kit.
I will be pulling the one that is problematic next weekend to see if I can find the problem, then decide if I really need a recone.
bought it used and it seemed to make a little mechanical noise when I hooked it up. Then it sounded like slight fluttering with higher frequency bass(rock). but wasn't bad. noise would stop if I pushed one side of the dustcap, get worse if I pushed ont he other. so in case there was a small gap I epoxied it. now after a while there is constant like sub fart noise with higher frequency bass, still kinda goes away when I push that side of the cone or dust cap.
anyway I think the model you are looking for is the opti1533d.
i have two of these
sorry to threadjack, but if someone could give me a few ideas before I pull it out to look, so I know what would be good to check. I would appreciate it. aside from that annoying noise is fine, freakin' slams the lows, picks up much lower than my AQs but the opti's are in a sealed box right now.
