Excited to begin my build. Could you send the Pi 4 plans? Also how narrow can I go? I know the internal space needs to be keep at a minimum the space called for in the plans but I would like the cabinets to be as narrow as possible.
The seven Pi model is two feet wide due to the midhorn. And while I appreciate the matter of size - if it doesn't fit, it doesn't fit - there is also the issue of feasibility and whether or not the corners and room dimensions are suitable for constant-directivity cornerhorns.
I'm glad you're researching this. I'll bet you're going to put together an excellent system!
