You guys are way to smart, yes, I will be porting th cabinet as well, and this way I have it covered, if it needs to be pulled out for any reason, will be easy to do, and if the porting of the cabinet works as expected, the M80 can just sit in the cabinet and not need to be pulled out.
In case any one misses the post, the Halos are not here yet, will be a week or two, the pic of them in place was just a cut and paste job to give me an idea as to how they will look, its to sacle so should look like the picture.
The Halos actually measure out to 17-1/4" in width, like most components do. So they will still have about 2" of clearence on eash side to the wood.
