That's easily missed. (and only ScottG gave me a smile )

Of course there're some major differences between Watson and my setup. But the principle of enhancement in ITD is in common, I believe.

It may not be theoretically (or pollitically) correct, but compared with my previous 3-panel (3-channel) in optimal linear matrix and the following SSS (in single panel), this setup is indeed better in many ways, especially in imaging of course.

(The 2nd best is, except for the cheap pine boards for the baffles, I didn't buy anything new, all spares. )
Not missed But it's more of a distributed system than a pure SSS

You got all the essential elements for a good sound in your system: SSS panel with 0.5 matrix, slot loaded dipole bass, dipole midrange and flooded tweeters.

This is how the industry wants us to listen to music (and movies). Although, even they have recognised that generally people are not willing to install multiple of speakers in their living spaces. Thus they have to make them disappear..


I think the SSS makes the necessary disappearing act but still having the attribute of being tastefully designed

I think heights and wides in the front and the back are enough to generate realistic sounding spaciousness and envelopment for sound sources on a horizontal plane.

I would be the first to throw out my multiple speakers if a single speaker could produce the spatial qualities I'm looking for. It's not just some evil plot of "the industry", it's simply a necessity if one wants the widest possible range of auditory spaces that are controlled by the recording itself.

This is interesting concept and cool name: Acoustic planetarium

Look, it's SSS Speaker designed to operate with room reflections.

Click the image to open in full size.

Reality Media Lab.

"We research about the completely new sound providing method "acoustic planetarium. "This method is by placing enclosure which is installed several parametric loudspeakers in the middle of the room, these speakers emit the sound like a planetarium projector and we can experiment auditory MR on anywhere.
Parametric loudspeaker which we use have highly directional. This enables us making 3D sound field by emitting sound anywhere and reflecting or spreading it with wall or reflecting object. By this way, several people can share the sound field without mounting headphone, unlike the traditional system.
We define the MR system with acoustic planetarium and the MR world as "X-Media Galaxy," and aim to realize the 3D space with high presence which people have never experienced so far.

Ideal for a small room, like in the pic LOL

8 speakers ? Sounds like Ambisonics with height, the periphony

If tiny sweet spot is not a problem, then adding more speakers may be allowed. However, the sweet spot gets smaller with increased number of speakers.
5.1 having smaller sweet spot than 2 channel stereo ! (Of course the marketing material tells otherwise, how else they could sell plurality of speakers to fill the poor consumer's living spaces..)


Interchannel Interference at the Listening Position in a Five-channel Loudspeaker Configuration

http://www.tonmeister.ca/research/pubs/martin02a.pdf

"It is commonly-accepted thinking that the use of a
five-channel surround sound reproduction system
increases the size of the listening area over that
for two-channel stereophonic systems. In actual
fact, for many types of program material, the area
of this so-called “sweet spot” is reduced due to
interference between the channels at the listener’s
ears.
This effect is described and analysed through
theoretical evaluation and psychoacoustic listening
tests.
"

Or even more than 8. Depends how much one is willing to do. Forget about Ambisonics, recording techniques are not going to change. What might change is how sound is stored. We need to get rid of systems with a fixed number of channels. And some work is done in that direction. With such a new approach the user can choose the playback system that suits him best.

It's a fact that the sweetspot is small and all recorded music is really just made for a single seat. Doesn't matter if stereo or multichannel. A center channel helps. By the way, a single stereo speaker works by the same principle. The only difference is that there are no real side speakers but wall reflections.
