Here's my original critique of the cabs from 3 years ago....
NCD: Ampeg PN-115HLF NEO Cabs x 2 | TalkBass.com
Currently, I'm still very satisfied with the cabs. From my original mini-review of the cabs the only issue that's a non-issue was a vibration developed after 2 years of use. I grabbed a screwdriver and pulled the grill then gave a very slight turn to each screw on the basket, replaced the grill and I'm good to go. Rattle and vibrations are gone.
After 3+ years durability has been satisfactory, it can be relatively easy to get a mark or scratch these cabs but it's also easy to mask with a black marker.
I picked up a wireless last year and have been able venture out during sound checks to give a listen. From 50-75 feet the cabs sit nice. My preference is a "bass" heavy tone but the cabs are pretty neutral and will take what you give them. Not by choice but I've also have had the need to crank up the volume a few times because of loud guitar players and an oversized stage and I've never heard a "fart" out of these cabs.
I also found a pic from when I first purchased these cabs. I still have the IIPRO as well.

The amp that I am thinking of marrying these cabs to is a DB750, I have been thinking about them for a while now.. these or a pair of used HT115's. The MB Fusion that I just bought probably is going to get married to a Mesa PH610, I am thinking a hard on that.. it sounded just so dang good!
I want to thank you for your feedback on these cabs.. I think that I would prefer the 115's over a pair of 410's..
I think GK always seems louder than their rating. At least IME.
I had a MB800 when they were first released and it was just stupid loud. Sounded pretty good to me. Just not great and didn't care for the feel of the pots.
The Th500 is very well built but I just couldn't get a tone I loved out of it and it felt a little underpowered.
Yes, there is no doubt about it.. the GK produces sound.. of course the TH500 was used.. but it just so lacked everywhere compared to the GK..
