Perforated Da-lite or Oray-screen

Indieke,


I am unfamiliar with Oray screens, but I am very pleased with my DaLite AudioVision perforated screen, which was affordably priced, provides a detailed picture, and has very good sound properties.

Hi,


beside the acoustical properties of the screen you should check whether there are no optical problems. I had a severe loss of resolution with a DaLite AV because there was a nasty interaction between the holes in the screen and the pixel array of my XGA DLP projector. Try to get a sample of the material an test it with in true life condition by hanging it freely in the indended viewing distance. I could see the holes from normal viewing distance about 1.8 time screen width. And be sure to have nothing reflecting or leds of equipment behind the screen. This all will cause annoying problems. I ended with a screen from Da-Lite which is partly acoustically transparent but only at the masking below the white screen area wher my center is placed.

Oray has two types: accoustically transparent, classic, with hole of 1.2mm I think and the Microperforated, much more expensive (3x), with holes of 0.5mm.

Yet, the issue of the the holes size is also very important, as stated, for the image: even a CRT image can get affected by the holes so I guess the Microperforated is the stuff to go though I am sure there should be other manufacturers with cheaper prices. does anyone know the prices from Dalite and the size of the holes ?
