Once you have the woofer section working, you can always experiment with other horns, if the tractrix doesn't meet expectations.

That MTM from post #397 definitely looks nice but the ratio between wavelength at crossover and ctc distance is even worse than the ratio on mine. But I would still like to have a listen to these.

The pros and cons of MTMs are well known.

Still, this was a quite a succesful speaker:

Whereas this wasn't:

However, this was mainly due to the small price difference.

That's exactly what they sounded like to me.

I strongly disagree on this. I have heard all of the Western Electric (or WE-inspired) systems exhibited by Silbatone at the various editions of Munich High-End in recent years, and while they surely sounded "big" and "showy", they were also invariably "coloured"...
for lack of a better simile, the sound seemed to come from the back of a tunnel. NOT natural or realistic AT ALL.
They may have been state-of-the-art in the 1930's and '40s, but today we can do MUCH better.
Sorry to burst other people's bubble, but I like to tell it like it is.

The wide Bi-Radial horn is probably better for a MTM than the M2 WG with regards to vertical spacing, but it'll never approach Snell's eXpanding array.

Speaking of which, all Audio Note speakers are basically improved early Snell designs:

I hope the "big 2 way with car Subwoofer Sound" doesn't apply for all Ocean Way speakers.
They have their followers of whom I hope that they are not all deaf. At least their demo studio looks impressive (apart from the colour of the lighting):

HR1 Stereo – OceanWay Audio

They even have a large MTM using what looks like TAD 1601. What I don't like is that they seem to use a 1" HF Driver :

HRA – OceanWay Audio

It's not 'my' bubble at least
Did you also listen to the WE 757A monitor?

I agree, the large snail horns WE13, 15A etc. and subsequent pre-war WE cinema speakers are severely compromised designs.
The drivers are exceptional though, even by today's standards. Especially the 594A.
If you dismiss these, you dismiss nearly every high-end compression driver, including the TADs.
However, this is not the thread to discuss vintage gear.

The post war WE757A is a completely different animal.
While it'll not deliver the extension we're used to these days, I am convinced of its technical concept,
including the KS-12027 horn, the 713C, the WE728B and the well thought out crossover.
Considering this speaker is more than 70 years old, there's no bubble to burst.
This is a landmark monitor speaker.

Charles, I am sure those recent Ocean Way monitors are better.
I would prefer a Strauss MF-2 over any of these though.

It appears they've revived both the 25 year old JBL K2 (S-9500), as well as the Usher D2.
