Lumene Coliseum Silent UHD 4K Acoustic (Motorized Projection Screens)

Place the front speakers behind the image, as in a cinema: this is the principle behind Lumene’s Coliseum Silent UHD 4K Acoustic range. Its tensioned screen features 92,000 micro-perforations per square metre, enough to let sound through without affecting the UHD 4K image. Dialogue comes from the actor’s face, not from a cabinet placed beneath the screen.

The 0.8 gain makes the image slightly less bright than a conventional white screen (gain 1.0). This is the trade-off for acoustic transparency, to be offset by a sufficiently powerful video projector. In return, the 150° viewing angle keeps the image uniform across the entire width of the sofa, with 99% colour reproduction.

The 20 W DC motor stays below 50 dB and starts with an S-curve that eliminates jerks and protects the screen, over more than 20,000 cycles. The black aluminium casing can be mounted on a wall, ceiling or suspended. It can be controlled by infrared, 433 MHz radio, RS232, RS485, dry contact or 12 V trigger for home automation. The range includes six sizes in 16:9 format, from 92 to 180 inches diagonally.
