Hello,
the first project of my DIY loudspeakers i have served Ti6k- JBL. My first contact with
them, was in distant 2005.
I started working with them in 2009 and finished in 2012.
The loudspeakers are "SEAS"- Excel / Tw-1”, Mw-5”for center 2х 5.5”,Bass-8,5”/ and cross-over parts- "Intertechnik".
Have are some pictures, if there is interest, i will continue.
Regards!

Ofc there is interrest.
So what hurts eye why BR exit is at the bottom?
Im curious how you designed crossover. What were predicted crossover points? Maybe some measurements looking at it from perspective of crossover.
What is aluminium doing there?

Can you rewrite the speaker models? See some hashes.

Some very nice pictures in that collection, and some impressive curved wood finishing. Looks very nice, the gloss finish in particular. I bet that took a few hours of rubbing down to achieve.

Nominal impedance- 8 Ohm
Freguency Range 30Hz-20kHz
Characterstic Sensitivity(2,83V/1m)- 87db
Long Term-110W

 Do not understand what you are worried that a phase inverter is the bottom?
All my models are such - I like that.  Of course requires proper venting, which will show the other projects.These speakers have their happy new owner.
 The first image is a "matrix" of her bending 8 layers x 4 mm MDF/ not to participate in the construction/.
This aluminum foil  is to not to be glued the initial layers in bending.
The loudspeakers are "SEAS"- Excel T25CF002, W15CY001,W22EX001

Thanks for the good ratings!
Believe me,you pretty far with those "few hours".
After 10 coats based, on more than 20-25 with  acrylic auto varnish and after each layer- polishing.

Joro

No, I was just curious about crossover. Mid high low. Did you made any measurements?

Thank you for the incredible interest in my projects - this project is whot  you see to you every day!
An interesting situation, nobody asked me what happened to the column volume in such ventilation!
How will we calculate the volume in this complex form of ventilation?
