Fi BL?
 

i bought this sub off a dood, he said it was a FI BL, i pulled it apart today for the recone, and stamped on the motor is, "QD7" 15", so obvioussly its from a 15" sub, but what is QD7?, or is that just a number for the motor?

by the way the basket is a 18", with a PSI re-cone, 3", 8 layer aluminum flatwind, dual 2, its burnt to shite!!!
too much showin it off...haha

Hahaha I hope this turns out the right way ...
I'm just laughing at your description and the story, not YOU lmao

Never owned the BL's but there's a lot of members around here that have or currently do, hope they can help you out.

Most high end subs can be reconed, sometimes folks want a bigger or smaller woofer so they change the basket and recone to the wanted size. The PSi recone should be the give away!! just call them and get another re-cone.

ya man, thats what i figured, and i know about changin baskets and whatnot, what i was askin is what does the qd7 stand for, i am ordering the psi, as thats what i had, and it worked VERY well,

this is the sub in question

anyone shed some light here......im ordering the PSI, the one this had in it had 3 spiders, whats the best setup to order 3 medium spiders like what i had, or 2 heavy, or what....i cant really afford to just keep tryin diff setups, so im askin whats worked for you, as far as spider combinations, for coil im goin the same 3" 8layer aluminum flatwind,dual 2, but wanted to know about the spiders....so....help a bro out!!!

probably means quad dual .7 coils ?

Doesn't make much sense....

I think he said that the QD7 was stamped on the motor not on the recone. It could be a series of motor that was made and that number corresponds to a gap diameter code, coil length or something like that.

To me it looks like something that PSI had and it also looks like a an old Shocker motor. But I haven't been around in quite a few years so maybe things all look the same to me.

ya....thats what was on the motor.....its says " QD7....15"....and is what im trying to find out....i dont really need the info as im ordering the exact same config i had, but its always nice to know exactly what you have bangin in ur ride right?
