The large lab at Ambiophonics Institute houses the initial experimental no- compromise, high-end, 3D Ambiophonic system featuring front and dual rear full range SoundLab electrostatic Ambiodipoles, and electronics for the system's 30 speaker channels.  Shown are some of the 24 SoundLab Surrstat electrostatic ambience speakers being driven by convolvers using real stored concert-hall impulse responses, thus allowing Panorambiophonic reproduction of most existing stereo CDs or LPs. A video projector and parabolic screen allow 5.1 operas, concerts and movie soundtracks to likewise be reproduced Ambiophonically.




Using curved electrostatic SoundLab Ambiopoles to form an Ambiodipole results in a wider and much deeper optimum listening Area.  This single Ambiodipole provides a stage width of some 150 degrees from almost all stereophonic sources.




In back are two pair of SoundLab electrostatic Ambiodipoles: the furthest rear pair reproduces back surround channels of 5.1 or specially made PanAmbiophonic 4.0 surround recordings (360 degrees horizontal only); the nearer rear pair widens the front stage to almost 180 deg.  (Alternatively Acoustat 1+1s.)




24 full-range SoundLab electrostatic panels on two balconies as well as surrounding the listening position on the main floor reproduce height ambience derived by convolution from full sphere impulse responses.



Getting Ambiophonic's psychoacoustic benefits even on a budget in a small room.   The 12-channel listening room at Ambiophonics Institute uses a Bose AM-5 satellite front Ambiodipole/subwoofer, and LCD display. Not shown are the two AM-5 satellites  used as the back Ambiodipole and the eight used for surround ambience.




The back Ambiodipole pair of satellite speakers widens a CD stereo front stage to almost 180 deg, or reproduces specially made PanAmbiophonic 360 deg surround 4.0 recordings, or reproduces front and rear stages extracted from 5.1 surround sources.
