Steve, I've only installed the no-rez in the lower section so far. 
My cabinets used early prototype braces so  there were a couple issues that have been fixed for the  production runs (braces now have 2  larger holes, one on each side for wiring).  I only had 1 small hole in the corner to pass the wiring through, it was not adaquate. The spacing of the braces makes it pretty much impossible to drill an additional holes at this point so I had to run  the  woofer and mid woofer leads through the  large brace cutouts. I did  drill a second hole in the top brace so was able to pass the  tweeter and mid  woofer wiring through those .
Once  the  inside wall at the top is  covered in no rez,  the wiring will all but disappear aside  form the leads running across to the terminals.
The included cross over boards fit  perfect between the no rez, they can be  secured with just one or two  screws, the no rez keeps them in place and they are sitting on small  rubber feet.


Guy,  these are being driven  by a Dodd/Richie protype amp, abouit 8  extremely linear wpc  (4 ch) with a Dodd variable gain pre  (both battery)
