This is a little bit blue-sky, but I will be implementing as much of these ideas as I can into my new Listening Room/Home Theater.
The main innovation is the L/R asymmetry at LF, while remaining L/R symmetrical at MF and HF. The purpose is to place the LP where LF modes are minimized.
Also, in theory, if reflections are all handled properly,there should be an ideal speaker position which applies to all speaker types, except for toe (angle) adjustments.
Design Features:

Design Features:
- BEST OF BOTH WORLDS:
- L/R Golden Mean dimension ratios (1.618:1) at Modal Frequencies
- L/R Symmetry above Modal Frequencies
- “Treatment Walls” are 2x10 framing with insulation, inner surface of Treatment Walls can be varied to change HF/LF room crossover freq
- Exterior Walls also covered with framing and sound absorption material
- POTENTIAL DOWNSIDE: unsure about directional characteristics of sounds between ~80 Hz and ~200 Hz, but can vary the room crossover freq if need to
- First Reflection "Trap”
- No Parallel Surfaces at HF
- Not intended to eliminate LF modes, but extensive damping at LF to tighten bass
- Treatment Surfaces:
- Front of room: Absorption plus Selective Diffusion
- Selective Diffusion = NO EARLY ENERGY on reflection path from speaker is directed toward the LP
- Rear of room: Diffusion
- Proof of concept version easily changed with unfinished appearance, final version can have more finished appearance, still be changeable
