Ok guys,
I know this took forever but the woodwork is basically complete!  Big thanks to Ond and vaderag for always checking up on me along the way.  
Ond I gotta say there's certain details to this build where I realized you were being very precise for a reason.  When the top CP board was aligned slightly above the CP backing to hold the marquee glass in place, I felt the magic happening on its own.  Superb attention to detail.
vaderag,
I've finally reached the part where I'm going to try out your "bottom" marquee t-molding cut and placement.  In the two photos, I wanted you to confirm the following if/when you get a chance:
Is your speaker wood panel and bottom marquee aligned like this?  From your photos the black paint does a good job camouflaging the angles joining.
Lastly regarding the plexiglass groove.  Is the groove you cut like option #1 or option #2 in the link below?  In other words, is the groove starting at the edge or not? For demonstration purposes assume option #2 is on the same side as the t-molding cut in the middle.
