Giant oblate spheroid? unity horns

Interesting looking speakers, they do not have much depth so can't be conical horns.

I'm vaguely remembering the OS contour had some issues <1kHz? thoughts?

Interesting speaker: are dimensions given? Then one could estimate directivity. Speaking as a qualified owner of a pair of Unity speakers (albeit somewhat buggered 😀 ), I can answer: "Don't know." Perhaps a good place to hunt up data is on gedlee.com or the sometimes enormous Geddes threads here. His speaker waveguide x-over is around 1K, so probably would not matter in that case!

Those look like Synergy variants (note the slots, probably for midranges). Conical horns don't need much depth in particular, depends on what their coverage angle is set for -- mine are basically conical (90 degrees) and they are quite shallow.

Looks quite big, love the design!

looks like the slots are exits for bass drivers, no? i can't link the rear view photo to here but it looks like a three way design and i estimate the mouth is close to three feet.

Here is a rear view:

The person apparently responsible is Jeffrey W. Jackson, formerly of "Wheel Fi", and currently "A for Ara"

I can see a BMS logo on the apex-located driver.

Here is a philosophical question: If the horn angle is expanded to 180 degrees, is it still a Synergy horn? 🙂

well a baffle is a a kind of horn (imparts directivity), hard to get the drivers within 1/4 wavelength though (the mids also need to be within that distance of each other).

Hard to tell from the pictures but I would agree probably a 90 degree conical horn. Looks like the company is a rich mans plaything (Esty founder). Its neat they have broken the symmetry a bit with the 3 midranges. I would love to see the mid/woofer pads without the drivers as I can't get my head round how they pipe into the horn.

There is a picture without drivers if you follow the insta-link in the first post

Have a look at fig.8 in the synergy patent.

Seems to me it would simply be a slot loaded speaker.

Jeffrey Jackson is into all kinds of incredible/exotic things - usually related to vintage RCA gear. He has partnered with that fine fellow Dave Slagle on many projects.

I think this is quite a good surprise when a traditionalist perfectionist is turning his attention to the SYNERGY idea.

Or a flat baffle, in which case "horn" makes no sense. This thing is awesome and I'd love to hear it.

Actually it might be doable, if we use a small flange-less tweeter instead of a compression deriver. For instance, the Peerless XT25SC40-04 1" Ring Radiator has a diameter of only 44mm.
