Yes I Found everything in german and part of it seems to be a european version with a different port/tweet/woofer alignement... And most part of it seems right. But thanks for everything guys. I also wrote to Glenn to see for the cabinets but my goal is save and make it as original as possible without the "mysterious duct port factory mistake" I read since I began this fascinating speaker project. Here's the precious link I Found for the blueprints

"the "mysterious duct port factory mistake""
You'll have to clue me in about this. What mistake?
:)
Hi, It's an old tread I read a while ago because the sentry III cabinet is actually having one main challenge: the double tuned ports. Sizes, lenght, version 1,2, contradictions of the original* exacts sizes, variations of the lenght of each port sides, etc. And after reading on this issue, I realized on most of the sentry III pictures, the square holes are ducts less, we can see the side and bottom of the cabinet.... !!! Excuse my english.
If I could make a certitude on the "lenght"(depth) of the 8 sides of the ports* (with or without the thickness of the front panel (thanks to mention)) that could be one great info for the realisation of this beauty.
You know something like from #1 port (upper one) and side #1 witch is at 12 o'clock and so on 'till bottom #2 port at 9 o'clock (side 8).
This is important for me to respect the engineering of electro voice. I do this project not to copy heart less somebody, because I would just make two 3" round ports tuned with the box and woofer with impedance sweep and free enclosure software. I want to reproduce these Sentry III in honor of electro voice
*not a copy enclosure
Thanks for your precious and precise help,
Simon

The Sentry III had two ports. The concept was to provide flexibility to the user. One port could be covered, or not. The included (?) EQ could be used to boost the output of low frequencies. I'm still wondering about your referenced "mistake".
I probably have the spec sheet around here somewhere, but it's not important enough for me to go find it.

Mistake from the maker: this is what jorb wrote at audiokarma and I agree with him.
- {Took me a couple minutes to figure out what I was looking at.
This is what I was talking about how the cabinet maker was cutting corners.
They should have used a side wall board that was 1 13/16 inches wider.
Or at lease match the the port divider board length. 9 1/4"
They did that because you don't see it. Cheapos
Does not really matter if you slide in some pieces of wood to match the openings.

The only thing is they go so much into confusion with the port sizes I Can't decode wich ones are the right ones.
If you take a look at the Picture you Will notice that the ports are related as what I (we were) was saying.

Your apparently, but maybe important, random capitalization of various words is puzzling.Please don't tell us that you're limited by your phone.
