I have a 12 inch JL W6v2 and the foam on the edges of the speaker is starting to rip! Its not so bad at the moment, but i believe if i continue pounding it the foam will eventually stretch longer around the edges. I have a 500watt rms MTX amp pushing the 12" JL W6v2, and i know a W6v2 can handle more then that. I have a few questions for those who may know the answer. Does any one know how to repair this kind problem? Is there any kind of glue material that will seal it from ripping more? AND HOW THE HELL DID THIS HAPPEN!?!? Could it be bad frequency? HOPEING FOR REPLIES A.S.A.P.

 

Well ripping is not usually caused by too much power. That will usually burn out the voice coil or spyder first.

I would look at something more along the lines of an object in the trunk. You can repair the rip, I would however go back to the dealer you purchased it from and see if they will warranty it for you.

 

I have seen this before on JL's. This is not caused by too much power per say - this is caused by too much XMAX (linear excursion of the woofer). Bets are, when you play this sub at highway power in the particular enclosure you have, you are getting too much travel.

This can usually be attributed to one (or a combination of) three causes that I know of:
Your cabinet may have air leaks.
If the cabinet is vented, your vent may be incorrectly designed.
Your cabinet may be too large for the amount of power you are throwing.

What is your scenario? I got the 500W MTX amp and 12W6 part - what model MTX? What CuFt enclosure and material (fiberglass, 5/8 MDF, 7/8 MDF, dimensions, etc.)? How do you have the W6 wired ( ohm load, parallel or series )? Do you have Grills? Are the grills far enough away from the foam surrounds at full excursion?

 

my bets on air leaks killed my test sub.
