I had two VHT Special 6 cabinets which I wasn't quite sure what to do with. They came with a crappy Celestion knockoffs, so I figured why not!?..
After what I spent for my stage and a few addons (rigs mostly, 2 JBL 308P monitors and cables to hook everything up..)
I wanted to get some Kemper cabs, but I was going to have to wait a while. So I again looked at the two cabinets, went to kemper-americas store and picked up a 2 pack of Kemper Kones and I just finished installing them in the VHT cabinets (Which are Baltic birch ply FWIW) and Voila two Kemper-Homegrowns!! I'm putting pics up just to show how easy it was..
Just waiting on my Palmer Macht 402 to show up from Germany now.. 
OH yeah I changed out the drywall screws they had in the back of the VHT cabinets for some nice stainless wood screws and some flashy dress washers.
This brings me back to my amp building days!! LOL
