821.Any suggestions on a bass cab?
You could delete the top portion that would normally house the 808 or 811 horn.
The horn loading of the 821 will give the system a better natural acoustic balance, and probably hel the 416's better track the dynamics of the 399/805's.
Just my .02................... lotsa room left for varying mileage.
Not all vegetables make good leaders.
If you decide to go the 820/821 route, I have a pair of 820Cs that I can measure for any dimension you need. Mine are a bit mismatched though, as one was built in 1955 and the other in 1957. There are some interesting construction differences between the two cabinets.

Your neighbors called. They like your music.
I also converted that 820 cabinet plan into a .pdf and uploaded to the Library. The file format is nice cause you can blow it up without a lot of resolution loss.
