Several design points could be addressed to improve both picture and sound fidelity:
The projector has a native resolution of 2000x1280, which is a 1.67 aspect ratio screen, not 4:3. Therefore a different type of anamorphic lens specific to this projector would have to be used, and upping the frame rate five times is only necessary for an ILA projector - modern digital projectors, as you know, refresh anywhere from between 96 and 240 Hz, depending on technology, negating this type of scaling.
This projector was first used by Lucasfilm to demonstrate Star Wars: EP1 digitally for the first time in 1999. Considerable improvements have been made in projection technology that result in far great image fidelity with respect to film. Also, several different technologies might be featured to take advantage of each's strengths, allowing for DCI prints to be screened exactly or better than in the best commercial theaters in the world, and even in 3D!
With such an ambitious space being designed and built from the ground up for 103 seats, shouldn't the concrete frame work be larger, allowing for a room within a room construction that would offer vastly superior sound quality before requiring what I imagine will be a considerable amount of acoustic damping and diffusion to dial out the concrete shoebox shape?
Light output in the mid 20 foot-lamberts is very very acceptable, but could be even higher, allowing for the possibility of a sharper and more realistic image or for an increased contrast ratio in access of this models current capabiity, which I know Cineramax would deeply agree with.
I'm still hoping to see a floor plan of the entire installation. That would answer many other design and application questions I have.
I hasten to add that this 3 - CRT driven ILA projector requires almost constant recalibration to stay perfectly linear with respect to color temperature, grayscale, focus, and convergence!
