Howdy Fella's - I'm Deon.
Obviously I'm new here. New to your forum, not to bass.
Such a sad parting to a decent driver !!!
After reading through this thread, I found a couple things to note.
The system was fed a 16hz signal in a 2.2 cubic foot enclosure, tuned to 32hz by an amp capable of running over 1500 watts at 1 ohm. That's the capabillity of dellivering 3x the rated power of the driver with a signal 1/2 the tuning frequency where it is completely unloaded and thus not protected by the enclosures compliance.
Given that enclosure size, tuning freq, and an unloaded signal at 16hz it only takes 350 watts – to exceed it’s linear x-max of 23mm
The A.V. driver has an X-mech of 30mm, and to jump out of the gap required an additional 1.5mm – or over 31.5mm excursion. With an Xsus of only 24.2mm on the RLP, that driver should not ever even be capable of moving 31.5mm.
Also The particular A.V. woofer in question that failed was built by T.C. Sounds, the same as the RLP driver. Not one built in house by A.E. Speakers.
My guess any driver with similar compliance and build would have never had a chance of withstanding that kind of torture //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Thank you, glad to be here.
Having recently joined forces with AE, I'll be nosing around here off and on..
Might be a first post - but I'm no not exactly a newb...//content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif
I did ask you details of the enclosure and tuning, the music played and your amp *before* I read the thread, correct..
Then I read every word in the whole thread twice, before carefully I opening my mouth.

As a Manufacturer, I have to be very carefull not to step on peoples.... *toes*.
