I think I have already suggested the large magnetostat from Expolinear side-mounted. Even a 38 mm dome starts beaming only at 5 kHz. The alternative would be one rear-mounted (high sensitivity) dome.

Are you meanwhile able to localize the front-mounted fullranger in your single stereo speaker?

I think with only two side firing elements the mono center sound is not as homogenous with side panned sound because in this case the direct sound is 90 degrees element off axis sound which is frequency dependent.
And, if the purpose was to attenuate the center direct sound for mono signal then normal 2 speaker stereo would be just fine.

The benefit of 3 identical elements with matrix is the ability to steer the main radiation direction according to the stereo panning. It works for center mono signal as well as side panned signals, with the help of side walls of course.

No, the speaker is not localisable if listening distance is kept proper and the psychoacoustic filter is used. The purpose of the filter is to remove some of the treble from the center element and boost the treble to the side elements, while the overall power response is almost constant.

Depends on your goals and tastes. This driver has very ragged behavior above 4Khz, as many drivers this size do. This not the same as a rising response, and what users cite as clarity is actually a cone that is poorly controlled up there.

This may not be a problem for the side firing units, as their output will highly diffused. The front unit may require a low pass at a much lower frequency than one might imagine in order to disappear.

nevertheless I am highly sceptical, what kind of SSS is that exactly?

Because some basic symmetry of the room layout is typically required by any SSS setup and I can't see any such symmetry at the pictures from B-O .

and this:
Quote:
Sound separation is excellent too with the wide diameter and curved front doing a fine job of dispersing channels around the room. Yes a HiFi separates system or x.1 surround sound system by definition would spread sound more evenly around large open spaces, but the ability of the A9 to compete with them should not be underestimated.
doesn't sound very promising.
