A buddy of mine has had his Jl W1s for four years now and "the voice coils came unglued". The heat and humidity are really bad down here making it tough on subs however, his were in a sealed fiberglass box making it more resistant to the humidity.
same as what happened to my kicker solobaric after 4 months of using..luckily i had my warranty claimed... and replaced a new one. i guess it always depends on how you use it..but it doesnt to be like that brah after all jl audio is one of the best manufacturers of sub woofers.. imho
i still have my very first subs, a pair of kicker impulse. bought them in june-july '96 and they still work fine. true they have only seen about maybe 8 years of use, but they're still holding up fine and play just as good as when i got them.
I have a set of Genesis (sp) home speakers (8" with the green surrounds and octagon magnets) that where high fidelity for there time in my work shop still playing from 1977 on a Hafler 100x2(only thing my father gave me of value), they play great will never get rid of them... Polo.
the subs ben is talking about are two jl audio W0's in a custom sealed box in a crew cab 05 chevy 1500 on a jl 250.1 amp. It was all done by custom sounds. his subs will work for about 5 min like they were brand new but then stop working for a while and then come back on again. i checked the amp and the light on the amp turns off. It doesn't seem to me like there is anything wrong with the subs but when he went back to custom sounds they said his subs were messed up not the amp. custom sounds has been known for trying to rip people off and i think its clearly the amp. because i don't see how the subs would hit perfectly fine and then stop working if just the spider or voice coils were coming apart. =/
Bradshaw, not that it matters but they are W1's, not the W0's. Did you all ever end up checking the coils or spiders to make sure nothings funky looking? If it is the subs I'm curious to try out the Fi X's in his box, they are only 6" in depth (the 12W1 is 130mm ~5inches in mounting depth).
