Subwoofer glue failures? What brand have you seen fail most often (glue only)

[Canaan 10+ year member]

I work at a car audio/pawn shop. We sell new audio systems, do pawns and trade-ins, and outright buy second hand.

We carry quite a few lines here at the shop.... but we see nearly every make and model 12v audio you can think of...from pyle to ID to Boston to supa-chrome audiobahn, old-school Rockford or Orion to walmart VR3 amps. I see it all, day in...day out.

Mainstream, underground, good, bad, questionable...I see a shitload of random stuff show up here in the shop.

Any ways. I have seen a pretty regular trend in regard to glue joints on some subs in the past few years.

We bench-test everything that comes in the shop, whether we are buying it second hand, or installing it for a customer.

2 mainstream companies tend to stick out for about 30-50% of the subs we see with failed glue joints. That is to say....nearly half of the used subs we see from these 2 companies have failed glue joints.

Usually the glue fails on the surround landing. And when I say 'fails', I mean literately half the surround has come unglued from the frame. The glue gets soft. It looks like these mainstream companies are using a glue roughly equal to hot-glue to hold their surrounds or even spiders to the frames. On a hot day you can actually peal the surround/spiders up with your finger nail!!!!!!

I just feel that its sad.

I won't say a brand names now, but if others comment and say they have seen similar ****-ups from certain mainstream lines...I have pics to show major glue failures.

From what I have seen, the glue usually makes it JUST LONG ENOUGH to get out of the 1yr warranty range.

So...

Have any of you see failed glue joints on any of your 'mainstream' brand subs?

Well, looks like we have a consensus. Kicker L7.

And yea, that's the #1 sub we see w/ glue failure. Pretty much all Kicker subs.

The other subs we see fail most often are Alpine.

I had it happen on both a 12" L7 and a 12" L5. IIRC the glue started to let go in the corners first, then that was all she wrote.

I've had a huge problem with just about every Sundown I buy, it's been a victim of either glue failure or a bad coil.

Probably because all I buy is blown ones. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
