Few days ago asked and get reply that it won't be released for me however milled model is ready. Two possible solutions: a kind of Kickstarter or find another CNC mill company.
Any driver special recommended for the tractrix 110 horn ?
Have pairs of ; Jbl 2251 , beyma 102nd , fane studio 10, fane studio 8 -( currently used),tad tm 1201(just removed) and lowter (pm2as )and fostex fullrange drivers laying around.
But do not feel confident about what to try next
Best Regards

Wait for Celestion 2050? I've designed new 200Hz EOS waveguide 90x50x50cm, 60x30deg. It has smoothest response possible. First samples being laminated this week (not at horns.pl). Pair with faital 15PR400 in Onken - see visualisation. That flange at mouth is removed in production.

It will be used in pro cinema installations. Current production is glass laminate but depends on current investor can be more sophisticated (with airex, casted polyurethane etc) like Red Spade Audio PSE-144.

Sorry to interupt. But does anyone have a drawing for an onken tailored for the 15pr400?Pair with faital 15PR400 in Onken
I tried myself with the online onken calculator... But it seems that onken is not suitable for the 15pr400

Longer...or Port area too small...whatever I do...one of these is not sufficient. Then again ...I've never used it before....so it could be that I'm doing something wrong.
The Onken was designed for [vintage] Altec, etc., [mid] bass horn drivers, i.e. very high Vas, low Fs, low-medium Qts, but there's nothing special about the alignment, so for modern drivers you need to find the vent area required for a ~0.4-0.5 vent mach and calculate number of vents [more vents, the longer for a given tuning], vent length based on actual power likely to be applied at Fb Vs just using its peak power rating.
The only drivers I know that won't work are super low Vas drivers unless made oversize, then damp the longer than 'optimum' vents as required like the late Jean Michel Le Cléac'h did with his, but now can't find it in a quick Google search. 🙁
Don't have my Excel calculator loaded, so can't sim or check any on-line ones. I know Cyr-Marc Debien's Excel SS is correct though: https://www.google.com/search?q=onk....69i57j0l4.13121j0j7&sourceid=chrome&ie=UTF-8

Hi Jzagaja,
Nice large waveguide! Have you tried the new Celestion Axi2050, and if "yes", then what is your impression?
Thanks!
Best regards
Peter
