Hello I am looking for a horn lens for a BMS 4594HE. I would like to cross the BMS driver as low as possible. I found these
K-Horn K-HORN - Horns by Auto-Tech
iwata-200 IWATA-200 - Horns by Auto-Tech
seos-24 SEOS-24 - Horns by Auto-Tech
seos-30 SEOS-30 - Horns by Auto-Tech
Is one of those designs better than the others.
This will be in a music studio for mains with TD18H+ in MTM type config
Room will be about 28x25

Seos 30 will probably have the best polars. The BMS might show some strain at high volume with a 400hz crossover. Might be fine for your needs.
Quite a few people have had good success with that driver in the smaller seos 24.

Peter Morris at Soundforums.net had used these horns successfully in MTM configuration.
RCF HF950 -90 degree
Eighteen Sound XT1464 -60 degree

They will need to hit very high vol. I talked with the seller of the BMS and they said it could be crossed as low as 300hz and will play down to 200hz with ease. So I thought if we crossed at 400hz we would be fine. I was looking at the smaller seos also but it says it only good down to 550hz. There is a build here where they used the seos 24 at 450hz SEOS-24, BMS 4594ND, Dual AE TD18H+ - AVS Forum | Home Theater Discussions And Reviews
The seller also told me the k-horn he thought would be better than the seos. He was saying something about how short the seos was is why it would not work as well.
And thanks for your replies

For high level use that will probably be a safer choice. Although it will have more beaming in the highs. Might not be a big issue in practice.
That K-Horn is similar to the type that JTR uses in there speakers. JTR i think is custom horn. We need it to be no easy to blow as these get abused. They are in a non private studio that will be rented to the public and we often have customers that think that the louder the better 🙂
Make sure you set your limiters fairly conservatively. Don't want to read about fried drivers in a few months! While the AE drivers are second to none in audio performance, they aren't designed for the abuse that pro audio gear goes through.
Most people associate distortion with loudness. These drivers might fail before that threshold is reached for select individuals.

From what I have read about the AE drivers I thought they were extremely tuff. I read somewhere that someone was using them in pro audio gear for concerts and live events for like 8yrs with only one fail.
You said low as possible, then you said not easy to blow. These two are a tradeoff. They contradict each other. Directivity may need to be a secondary concern.
The type of horn can be different for these two needs. If you want loud then consider a narrow throat expanding horn, and accept its limits. If you want low consider something more conical.

300Hz waveguide, 1x0,5x0,5 meter, 60deg, 1,4-2" driver. Can be converted into synergy waveguide to save on drivers.
PM me for details.
So is the SEOS 24 good down to 450hz even though it list 550 as cut off ? And are there any polar's for the SEOS 24 or 30 I cant seem to find them any where
If the O/P's room dimensions are in feet then I would be more concerned about their hearing distorting and failing than the BMS.
How come the RCF HF950 can have a lower cutoff than that of 400Hz at half the size of the SEOS-24? What’s the catch?
True. More concerned about the AE drivers being in public control. People getting carried away with sustained bass.
I dont understand that either K-horn is much smaller also and can go lower. They seem to be longer though.
