help needed with WinIsd

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

Should be 50,8

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?).

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 it

DIY 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
