It will work. But there will be small resonances in the response curve because of the difference in angles. The driver has a wider exit angle than the horns entry angle.
The BMS 4591 has the same but opposite problem, compression driver throats, the driver has a narrower exit angle than the horn. Maybe the driver delivers a plane wave at the exit, then not a big problem.
One thing about the Auto-Tech horns. The have an exit diameter of exactly 2" (51,8 mm). The exit diameter of a JBL 2" driver is 49 mm. So you may have to make an adapter.
You also have the option to get 1.4" drivers and horns. The 4594ND-MID might have a 3 degrees exit just as 4594ND.

nice info. thanks.
I'm not expert in horns and I don't know anything about exit angles. you probably know Oris horns. Oris guy sells modified BMS 4592ND. I can afford t buy a pair of those but I can't buy a pair of Oris horns for about 800 Euros. do you think 4592ND will work in any of the Auto-tech horns which are less expensive (and look better IMO)?
4592ND reaches 114-115db of efficiency in Oris horns. I don't know if they will do the same thing in Autotech
This is a coaxial extended range driver. It will not work well on a traditional horn. Maybe on a waveguide.
Go for two traditional drivers instead, one with 2" exit and another with 1" exit. Use two horns. The Auto-tech JMLC-200T is excellent. The JMLC-1000 is also very good and can be used from 2kHz and up.
The Radian 650PB will fit the JMLC-1000. Or use the BMS 4550. Same problem here with exit and entry angles. The Radian has a nice exit angle, but the BMS has too wide exit angle. You can get BMS from USSpeaker (you are US citicen?).
Xmax of 7 meter? Wow
LOL! I didn't look at the specs, but considering it has a 380 meter diameter, especially with no Sd, a 7 m Xmax isn't unreasonable!
A program that only uses Fs, Vas, Qts can calculate some totally unreal alignments!

I know I can go for 2way in hf section. BUT, is Oris a waveguide or a horn? 4592ND works fine in Oris horn so I thought it might work is a Autotech too.

Uh come on guys
don't be like that. first time on WinIsd.Uh actually after 9/11 it's among the top secret classified files in Pentagon
no I'm kiddin'. it's just Bob's CW1526 made by Eminence as a replacement for Klipsch K-33. that's itDIY Oris horns. Looks like tractrix horn to me.
Trust me, the 4592ND will not work well on these. You will get a very very small sweetspot. There is also something not quite right with this driver, if I remember correctly there is some problem with the transition from one diaphragm to the other. It probably works ok for pro applications, but I doubt it is suitable for HiFi.
Well he starts with a LOL! Probably only thought it was amusing.
a 380 meter diagram woofer in a well tuned cab will probably move the moon from planet!
or maybe a climate warming remedy as it might be able to shot back the Sun a bit
yes I'm gonna do this. but what about HF? I'll use Auto-tech horns + some hi-tech CDs like BMS or Radian...
I know nothing about La Scala.
But HF section will be excellent with the horns and CDs we discussed. If you got 2 free corners maybe a Klipsh horn instead of a La Scala? It will match horn HF better I believe.
I would never let such a setup come near a Behringer though. Go for a MiniDSP HD 4x10, it is very good value for money. Not too complicated either. You can do all kinds of IIR filters as well as parametric EQ and delays.

I don't have a Klipschorn, nor can I build one. it's hard to build and I just don't have the time. La Scala is much more nostalgic to me and doesn't need a corner. La Scala is a real horn bassbin while Klipschorn behaives a direct radiating all in all which need a room corner to complete the designer plan as a horn.
there is also Vittora speaker with a horn bassbin inspired by La Scala but with more solid and better structure. with a curved profile it sounds much better. it looks nice too. it is the best Horn Loaded Bass Bin ever build IMO
I already have a Behringer 2496
how come you think it's not good? I think it will do the job in the right manner, complication is not important to meVittora:
