Rectangles are hard to get right -- for my next set of cabinets I'll be making a router jig for them.
If you don't rebate the horn the cut out isn't critical but no way to get 'round the appearance of the vent.
Cheap trick is to craft a really square vent box and get it glued on to the baffle before glue-up just right. Then, make the cut with a flush trim router bit. The vent box is your guide.

I'm not going to recess the horn this time around, but next time I will. I'm thinking about making a jig or even trying to get some CNC time.

Thanks for the tip. I tried using the vent box as a guide for the jig saw. I really wish I knew this before doing it -- I would have picked up a flush trim bit for the job. I didn't want to use my spiral upcut bit for fear of taking too many chunks out of the vent itself. I bought a router specifically for this project so I'm not too experienced with it and have a sparse bit selection.

Can't wait for the rest of the stuff to come in!
Just waiting on the components and a couple cables now.
Note: it looks like the posts under the mains go through the bottom of the cabinets, but they don't. I just happen to have my HTIB speakers sitting inside the cabinets temporarily and they are the same size and color as the posts.

Looking good, although i would want to try them sitting on the shelf. They would be positioned almost perfect for listening. I believe Wayne recommends roughly 15" off ground.

Thanks. I thought about that in my design -- originally they were supposed to be even higher. I may drop them down some more or eventually put them on the shelf like you said. I'm trying to compromise with my wife on the aesthetics so I can keep these in the living room.
Anyway, here is an updated photo from when I called it a night. I installed the R13 and added a divider that also acts as a support to keep the shelf from bowing under the weight of TV and the mains.
I'll probably build a 1pi for a center channel and put it right under the TV, and add four more in the future for full 7.2 audio.

I love using one π or two π speakers as surrounds. That's really what they're best used for, that or a small stereo. But I'm not sure I would want the center to be different than the mains. I would probably go with a phantom center with your layout.
