I had the same thing happen to my spl12 sub. It's just the dustcap that comes unglued and takes the top layer of thin paper with it. If the cap was glued to the actual cone and not the paper it would probably hold better.

In the later models of the subs mach5 was drilling holes in the dustcaps to relieve the pressure.

 

It's not coming unglued at all. just tearing the paper.

 

If it's tearing the paper it is lifting. Just give it some time and it will come loose. Took about 2 months with mine like that to realize what was happening. I thought I had folded the cone, but it was still burping fine.

 

not gonna lie those subs dont sound too good if the dust cap falls off of them lol

 

This happened on the first version of the old SPL, no pressure relief vents.

Nothing to do with this new motor.

 

^^how did you guys handle warranty claims with those versions? That's the important part and determines how the company should be treated with regards to new products. Did you require the purchaser to pay for shipping back to you etc..

 

I would say considering its an spl sub, most spl'ers woulda drilled holes in the cap and glued it back on. alot of subs were like this and used them for spl not daily

 

Humm need a tester.. i will take 2 18's give them a try

 

Mark was the absolute BEST person in the world to deal with. Since I had two of the first SPL 12s to come outa winnipeg and the dust cap issue happened the first day, Mark sent me a recone at no charge, when it happened again he sent me another recone and the "vented" dust cap.

I would never hesitate to buy from Mach 5 Audio ever again.

Also, the issue causing it was no vented pole piece. Looks like we have one on the NEO

 

These happened to mine 2 free recones mark rocks
