“The acoustic transparency is not perfect. It’s worse than a speaker cloth.”
Perforated AT screens act like reflectors giving a ‘phasey’ sound and uneven response that can’t be corrected with simple equalisation.

Fabric screens only suffer minimal high frequency loss due to absorption, which is possible to correct with basic equalisation, or even tone controls.

“AT screens present a surface granularity, that blurs the image and reduces resolution.”
This is true to some extent, but our fabric is engineered to have a fine weave that does not limit viewing from normal distances.

The important criterion here is the resolution limit. If a pixel can’t be seen from a very short distance from the screen, then the screen is the limiting factor. If a pixel can be seen distinctly then the projector is the limiting factor, which is most often the case with very fine fabric screens.

“AT screens do not provide gain or, like the latest technologies, contrast enhancement.”
This is true, however, such screens are mostly used to solve severe problems in bright environments. High end home theatres are always installed in lighting-controlled environments, where screens providing unity gain (or very near to 1) are the best choice.

“AT screens are more expansive than solid ones.”
This is correct. But what is the cost of a screen compared to the total cost of the installation? Typically a few percent, sometimes up to 10%, not more.
