I was a cabinet maker in San Diego, and as far as I know, I built every KeveK cabinet ever built for John Bradford. Hundreds of cabinets!
As I type this I am looking at my ES-12s across the room, and they still sound great.
A little insider information here, I once asked John about the unusual name for his speakers and he told me that his dyslexic daughter was doodling one day and came up with the name... but you need to understand that the "K" at the end was written backward, which is how it is on the metal tag on each speaker. The name as viewed in a mirror is the same as when not viewed in a mirror!
