the project very interesting,,i see no separation between drivers at the back,,can you tell me why you choose that?

I read through this article from 1982, and find that it largely covers what we know today about hearing, all was known back then.

There are some things left out, such as the fact we can hear well below 20hz, and perception also depends on tactile information from skin and body resonances.

The article concludes - "Future" - that performance of sound reproduction systems matches our hearing performance quite well, though improvements can be done, and that the big remaining challenges are related to acoustics and localization.

The technical limitations of 1982's equipment has now been overcome - we have can have full dynamic range, no audible distortion, no noise. Back then, there were very real audible differences between amplifiers, tape machines, vinyl playback. Those differences live on in our day in the high-end world, but they are no longer part of psychoacoustics, it is pure psychology.

Recent advancements in audio reproduction has been seen particularly in the reproduction of lower frequencies - full range systems with response well below 20hz, and full dynamic range exceeding 120dB, with awareness to tactile sensory effects. A big, capable bass system really makes a difference.

Awareness and knowledge about acoustics has improved how well a 3D-rendering of an event can be reproduced faithfully and realistic. But here, we still have to choose what we can have. It has yet not been achieved to be able to reproduce an event so that it sounds realistic with correct rendering of scene and room from the recording, when you move around in the listening room. With directive patterns and early reflections removed it all falls apart when you move away from the sweetspot, or if you choose wide radiation in a lively room the whole scene is diffuse and does not render each object precisely regardless of position.

how about octahedron speaker,,can that locate every instrument separately?
