and the sound room, lounge etc would have side, top and 'front' wall surrounded by soil/rock, at least. It would expand from front to rear in height and width, with some ELF peak tube-trapping, absorption and diffusion as well. Floor to remain level.

Bass? Either two bass horns (room-gain matched) which would be built in to the ground and emerge under the main front array OR distributed
room-gain-matched subs with adjusted delays to sum at listening seats.

Main front array (pair or three) of largish 'foamed-concrete' spheres with B&W style sealed-end labyrinth / tails out their backs turned from timber, inner surfaces covered in treated long-fibre wool over Deflex or BlackHole cut in strips of formed by them to special order to fit inner curves. Each FRange source's acoustic centre at listener ear height. Timber baffles made of birch-ply but with NICE thick outer veneer of Aussie hardwood CNC'd to fit without gaps. OR nice smooth leather over flat Deflex or Black-hole / thick flat long-life foam.

Use Manger drivers. Possibly several Mangers in a Bessel array on the front if it was a BIG room. Don't think I'd bother with a third central bass-horn.

Crossover? 120Hz to free the Manger or Mangers from excursion, but still covering all human voices. Steep as necessary.

IF soundfield / Ambiosonics? Gerzon ever took off add top - bottom pair / pairs also retimed.

Rears would be matching spheres, and could be fed by Left-Right / R-L differentially delayed signals to get comb-filter diffusion. OR by rear channels from SACD.

Needs absolute polarity switching at spkr level, Master and rear level control at seat, bass too? For all six amplifier channels (more if use dist'd subs.)

Delay/phase matching for distances from two-person sweet spot. Four-person if possible.

Needs a really high-end ADC to feed analogue into DSP box (& more for rears.) Audyssey or our own Aussie DSP mob or better.

LBNL I'd have to hear Silbatone's diffusers or Manger's own, on Mangers after I'd owned them a while. Then I - might - get them.

Keep making live acoustic recordings, and buy a Calrec Soundfield recording set-up now that price is not an issue.

Beforehand? Obtain a Trinaural box and live with it. Then decide. Possibly see if anyone will add Trinaural to their DSP / surround chips.

Sigh!
