I wouldn't mind having that diffuser on the back wall.
Although, it looks like it would be a PITA to keep free of dust.

As befit the galaxy-wide soundstage and dark backgrounds, this (per force, very expensive) contraption would throw , in the mind of its owners,Far Far Away?

Reminds me of the B&K omni speaker meant for measurement: https://www.bksv.com/en/products/transducers/acoustic/sound-sources/omni-power-light-4292
Comb filtering galore.But it suresoundslooks crazy in "standard stereo setup"
I've been eyeing NTi's SPL meter for a little bit: https://www.nti-audio.com/en/products/xl2-sound-level-meter
There are other "isobaric" designs, e.g., Linn, but the others mount both drivers inside and facing out. I cannot think of a valid justification for this arrangement which exposes the driver to possible damage.I'm new to speakers, does "isobaric bass port" speakers count for this thread, or is it adopted by more manufacurers?

That's cool, but I've not seen it before.How about this for old times sake:

You may note (from the filename) that the man in the picture is the esteemed conductor Hermann Scherchen who designed the speaker. There is a nice description of the design here: http://microphonesandloudspeakers.com/2017/03/10/active-loudspeaker-hermann-scherchen/That's cool, but I've not seen it before.
Actually, pressure inside the box does change, but the pressure of the air enclosed between the two woofers membranes does not change. And yes, it is an old invention by genius Harry Olson. It cuts required box volume in half and lowers the second harmonic distortion.Isobarik, meaning constant pressure. The two bass drivers move in phase, such that the pressure inside the box doesn't change.

Invented by Harry Olsen in the 1950s so nothing new under the sun.

Well, exposed back speaker frame is more sturdy than exposed fragile membrane facing out of the box. But ugly at worst... and "industrial look" at best.There are other "isobaric" designs, e.g., Linn, but the others mount both drivers inside and facing out.

Those look like the truly awful Lowther full range horrors or clones thereof.
