For awhile now I've been wondering how the PT800's would sound if the LE14H3's were in a bigger enclosure. To satisfy my curiosity and see if it would be worth actually building (or having them built) new sub cabs, I decided to use my trusty 240ti's as ready made -tuned enclosures; nice that they were already sitting next to the stacks.
I finally worked up the energy to explore this. I transplant the LE14H3's into the 240 cabs, and jump the speaker wires from the PS1400 into the bass port of the 240's.
But, tragedy struck!!
After 5 minutes of TRULY AWESOME sound I notice some extreme woofer movement on the right and taking a closer look I see the surround of my very new LE14H3 flapping in the wind...so to speak.
After promptly shutting it down and examining the situation, I find that over half of the rubber surround has come completely off of the basket. Party Over!
The next day, I check the surround again. Did I push the woofer too hard? None of the paint of the basket came off with the glue, the rubber surround is pristine and undamaged. But even more telling is that when GENTLY pulling on the surround that is still attached, it peels right off with a brittle crackling. Ive re-coned LE14H1's and I'm pretty sure that shouldn't happen! No problem with the other woofer either.
First, I wanted to bring this to the forums attention because this might be a problem for others. The PS1400 has a "purdy ring" screwed down atop the LE14H3, with an edge that sits right atop the LE14H3's rubber surround. If I hadn't taken it off, I doubt I would have ever realized this problem. Could the glue have been broken and the woofer been leaking air before I removed it? It's possible...
Second, has anyone had this happen with their LE14H3's? Has anyone dealt with JBL on an issue like this? I bought the PS1400's new earlier this year.
Third, if I don't get any love from JBL, anyone know if the surround glue for the rubber surround is the same as for the foam one's? It was still playing when it shut down, but I am worried about VC damage, though I think it's probably fine; don't hear any rubbing. If they use the same glue for the spider maybe I should check it too...
