With all the technology we have today I wonder how big a pair of Butt Cheek horns would have to be to get down to 30hz give or take. I think it would look good with three foot Butt cheeks, the BCs from the 4435 for midrange, and topped with the baby BCs. Might take a kind of big 3D printer but worth looking into.
The butt cheek shape is for mediums and highs distribution. Not needed on bass. It goes down to 350Hz it is already close to 32" per side.
Nonetheless expect a very large horn if a flat-to-30Hz response is needed. ;-)
The 2360 is the size progression up from the 2344 if I'm not mistaken.
Same concept and design. Different format for a different application. Mostly movie theaters. I have them at home an love them. Some hate them. Go figure.

The minimum horn mouth area to support 30 Hz would be roughly 10 feet square, with an unmanageable length. A smaller area and shorter length if deployed in a reduced solid angle. Considering the Bi-Radials were designed for the pattern control of high frequencies, it's unlikely that particular design would be necessary for frequencies that are omni-directional.
For example; Say you have a horn with a 10' x 10' mouth, and a throat area of 4" x 4". Your horn length would be 20 feet long. Shrink the horn down to operate in a reduced solid angle as one of a pair of corner horns, your horn length becomes approximately 12 feet with a mouth area of 7 square feet.
You could shorten the horn by employing manifold sections, and better manage the mouth area by way of a judicious choice of a Hyperbolic curve, versus an exponential.
If I had a choice between using Bi-Radial or Mantaray horns, I would use the Bi-Radial. The Mantaray horn has two built in design flaws that cannot be fixed. If the problems could be corrected, it wouldn't be a Mantaray.

IIRC, The 2360 provides full loading and pattern control to 350Hz.
They're big, but they do sound very good. If it had flanges near the mouth so that it could be mounted in a cabinet, I'd probably use some in a large PA rig.
In the 1980's retired NFL QB Ken Stabler bought a C&W dance bar in NW Houston named "Diamondback". It had huge bass horns in the corners of the dance area loaded with FIVE 15" cone drivers stacked up in a horn that measured ~7 feet by ~10 inches at the throat, ~12-15 feet long, with a mouth ~7'Hx12-15' wide. JBL 2350-Series mid horns hung on chain surrounding the dance floor, with some HF horn on top of them.
I loved walking into those horns and squeezing myself as near as I could to the woofers and being "energized"by them.
The DJ booth had a wall of amp racks chock full of BGW 750 amps with LED power output meters in an arc across the faceplates mesmerising me...
The 2360 has no provision for mounting in a box. It is usually fitted on top of the bass cabinet with a fixed wooden stand, or a steel swiveling stand.
IF it had flanges...
Didn't Western Electric do that (somewhat) with the spiriform (curled) shape?
3 foot tall but cheeks...I think I know her. And, there was a song about her..Bertha Butt
I could not help myself replying to this old thread.
I remember Bertha Butt she and Wanda were the Butt sisters.

They were:
Betty Butt
Bella Butt
and
Beth-Sheeba Butt!!!
...they called it the Bertha Butt Boogie...
No question!
