After looking over the FR curves on the azurahorn website, it seems I'd be better off using a 500hz horn with a 1" driver for the treble instead of a 200Hz horn.

Looking at FR curves is a good idea, but don't let that be your only guide. At 500Hz up a 1.4" driver (or perhaps a 2") will sound much better than a 1". You can ask Lynn Olson about that, too. I'm sure the difference could be measured, but it doesn't show up in simple FR plots.

If you want to cross north of 1 KHz, then yes, a 1" might be a better choice.

If you are trying to measure the entrance angle of of a horn you can use a General Tool #17 protractor.

If the measurement arm is cut down to 1/2" or so you can measure the exit angle of CD's that don't have the bug screen right at the exit.

Here is another impulse response measurement on a JMLC horn. The driver is the cheap parts express D250P-8 mounted on a 600Hz JMLC horn that I turned on my wood lathe last month.

I think the small ripples are from the high frequency ringing of the driver as seen below.

-with smoothing at only 1/24th, yup - driver (not horn, or rather this horn). The only exception to this that can cause "hash" is less than excellent coupling between driver and horn. But with you.. yeah, HIGHLY unlikely.

Big horns sound very dynamic. I have heard Hoktunas 200 Hz horns, they sound fantastic with a jbl 2441. They sounded so good I got myself a pair.

An externally hosted image should be here but it is no longer accessible. Please upload images instead of linking to them to prevent this.


I am using JBL 2482. I have only listened to them briefly, I have no place to put them yet. The small horns are LeCleach 1kHz horns driven by a Radian one inch. The big horns go from 300 to 2500.

Because they are circular they beam. I had to eq them about 6 dB at the top.

Are those things on the floor for midbass or bass? Either way, it looks like you are missing at least one channel.
It also seems you would need larger tweeter horns to reach down to 2500Hz. But if you add one or two channels, you could have chosen a smaller midhorn and run it from 500 or 600Hz. This is what I am doing, but your way is probably good too.

Those things on the floor are midhorns. They are too small. I need more mouth area. The bass horn you can see to the left behind the other horns, the lamp is placed on it.

The 1Kz horns just look small compared to the 200 Hz horns.

I still have not solved midbass myself. I will try to use compression drivers as low as possible. If they start to cut in my ears I will always have the Fane S 8M.
