I am currently assembling the parts to build a new set of speakers for my HT. The current drivers and speakers planned for each front channel are:
VLF, 1-4645C, up to 80 Hz
LF, 1-2235 and 1-2226, 80 to 300 Hz (each in their own box)
MF, 2-E120, 300 to 1500 Hz (Yes total over kill)
HF, 1-2426, on an Everest style horn, 1500 Hz and up
VHF, 1-2205, 8000 Hz and up
I have thought about building 2 boxes per side, each with a 15" and a 12". Both would have the same profile from the front (to provide a level base for the big horn) and have the drivers offset to allow them to be placed closer together with the boxes side by side. I would use the values in the JBL enclosure recommendations to allow best bass response for each. The discussions about "Imaginary equivalent tuning" leads me to believe they would smooth each other out and This way I can have 4 separate speakers at some point.
The HF horns would be in their own box, perhaps with the VHF installed too.
The two Subs would be below the projection screen with my current MTM center on top of it. (2-2123 and a 2416/2432)
All of these would be active crossovers with digital phase and delay correction.
The existing assortment can be seen here:

I am open to all suggestions and criticism and appreciate the help our members so freely provide.
Thanks,
