Yep, I do.
The SPL port should have been built into the wall with the daily port sliding into the spl port.
I would suggest rounding the corners over ,but you can do that will 80 grit to save your router bit. Shouldn't really have any port noise, down side is we won't know unless you get it braced up and nice a rigid. Other wise any vibration you may see/hear will be hard to track down.

He just wanted a loud daily setup not really for metering.
