From kick to midtop

Hi all,
Some month ago I built an Altec Voice of theatre (plan taken from members.aol.com/xxbase80a/voice.of.theatre/bau.html ) loaded with ciare pw387. I don't like it in the kick section, now I use 2 folded horn and a mt115 loaded with pd156.
Altec counsel to 2 configuration to mount the altec 811b horn, one on top of this cab, one inside the cab filling the airport. I choose the last one to convert my voice of theatre into a midtop. In order to increase the low end I make some modification.
I decrease s1 adding 2 flare and I reduce the rearchamber volume reaching 26 litres.
Here's some pics


Before modification

First step wood frame, I build two of that

Filling the frames with foam

Cover with 4 mm laminate plywood

I loaded the 811b horn with a p.audio compression driver, a BM-D440S
The crossover point now is 200 hz to 2,500 hz for 15" flare and 2500 to 5000 hz for the 811b horn.
Now I'm building 2 Omnitop 15 loaded with Eminence delta 15 so I'm thinking the next steps from my voice of theatre. I'm planning to add some wood filler and a phase plug and change the woofer for a eminence legend 1518. Because I want to cut OT15 from 200 hz to 1500hz and the voice of theatre from 1500 to 2500 hz.

good work fella.

thanks.
I want to reach higher frequency by replacing 15" with an eminence legend, but for this range of frequency 8" or 10" or 6,5" etc.. are mostly used. Someone have experience or opinion in that?

im designing a 6" horn at the mo,

It's a very nice build. Very hard to build and original.
