An update for those of you playing along:
When I received the Growlers, two corners were split pretty violently, indicating some transportation trauma. We couldn't get much performance out of the pair, and the cracked speaker gave up the smoke right as we pushed them past 100db at 15'. I feel bad about cooking it, but I do think it was damaged on its way here.
Jeff seems to agree with me as he is sending out a new driver, which I will slap in before taking these guys on a gig.

If the cab is cracked, make sure you seal it back up!

Yeah. It's just cracked down at the mouth of the horn, so I don't think it's going to play a part in driver over-excursion or anything. Here come the pics.
These show the two corners, what I call "bottom front" if the horn mouth is down.
Here's the mini shootout:
From L to R:
JBL VRX918S, Growlers, Yamaha SW118, Yorkville LS608.
Unfortunately we didn't get good performance from the growlers because, as mentioned, the driver blew as soon as we tried to crank them at all. One think I'll say, this is the first time I've ever put my SW118s on a "good" amplifier, and they sure sounded better than they ever have before.
Rule number 1 in subwoofer land? Power, power, power.
Everyone was also impressed with the SX300s which, in my opinion, are a real sleeper of a cabinet. Super durable, good quality, great loudness. They really come alive when they have enough power.
I'll repeat the test when I have a new driver for the JTRs.
Hey, another thing that leads me to believe the growler was bad... notice the strap. ONE of them was walking all around, the other didn't budget. It just wasn't performing.

I would be concerned with the break and how it unloads the horn. If there is an air path from the outside world to the horn in the middle of the path somewhere-as I suspect there is now, then it will not perform properly.
Not so much from an overexcursion problem, but rather a complete "detuning" of the horn.
In regards to the driver going bad, I suspect the previous user pushed it just to the failing point (let most of the smoke out), and you gave it its last breath.
If one driver went bad so easily, I would suspect the other to not be far behind, as the previous user probably was giving them the same signal. Now if during the fall, the magnet shifted on the woofer, then it would also fail early.
No way to tell without futher investigation.
The drivers in the Growlers are pretty stout, so something must be wrong, other than normal operation and it failing.
Can I have some more talent in the monitors--PLEASE?

That damage looks rough. I cracked the corners a little when I had them, but man, I could never do that kind of damage! It wouldnt surprise me if they were dropped a few times. Sure, I drove them pretty hard, but as of the subwoofer shootout, they were working just fine.
I'd be really interested to see how the LS608's perform against the Growlers. Those were some pretty sweet little subs.
Oh, and I dont think these growlers should be shipped around anymore... I just see the cabinets getting destroyed. I think they should be hand delivered from person to person. Just my .02.
Thanks,

Do we need a packing tutorial here?

I suspect the previous tester used the same packaging they arrived in; I would like to box them up better, but short of building a shipping crate and dropping them on the back of a flatbed, it will be tough to improve on.
FYI, they arrived to me surrounded by 1" insulation foam, then into cardboard boxes.
As for getting blowed up... Jeff sent me a new driver which I put in, and I actually offered to pay for it because, while evidence suggests the driver was damaged on the road, I still feel bad that the smoke got out on my watch. Jeff didn't take me up on that offer, though, as he seems very genuinely interested in making sure people hear his cabinets.
I'll get this test on track shortly.. just gotta get through these 2 weeks.

The edges should be covered in something rigid.
For instance, if you buy a new piece of assembled furniture you will likely find layered fiberglass and cardboard "corners" attached to the piece.
The reasoning of course is that the "corner" will transfer the force of an impact evenly over the object.
