132" diagonal front projection screen. The Screen is also a patented free piston planar transducer, with over 15 square feet of active diaphragm surface. The Screen is configurable as three or more audio channels.
The Screen, with three integrated, free piston, flat panel transducers, has more than 15 square feet of active diaphragm surface, so that the audio signals may interact with a very large number of screen perforations: the total surface percentage of screen perforation is much less critical than in a conventional, small diaphragm transducer. Further, as the patented free piston, flat panel transducers are very thin, three channels of ultimate quality audio may be placed behind the perforated, front projection screen, while the screen itself may be in immediate, near proximity to the room boundary wall, for best physical appearance and space conservation.
The Screen is a new, integrated solution to the large, front projection screen home theatre audio/video dilemma. The Screen incorporates a highly reflective front surface screen for maximum clarity and reflective brilliance. The patented, thin, large surface audio transducer elements radiate outward, through the screen and from co-planar room boundary walls, ceiling, and floor. Therefore, an entire class of room reflections, typically generated by free standing audio transducers, is eliminated from the three channel Screen playback signal, partially solving the second venue problem, which is that, no matter what the acoustics of the playback, home theatre room are, they are not the acoustics of the original recording venue. Therefore, if the best, most accurate, artistic intention of the auteur is to be realized, the second venue, playback, acoustics of the home theatre room must be controlled so that the original venue acoustics may properly shine through.
Transducer Type: Free, flat fibre composite piston, (not a tympanically tensioned film), patented, planar transducer. Drive System: Symmetrical, magnetically balanced, electromagnetic field transducer. Frequency Response: (With Linear Actuator V-Driver Subwoofer: From delivery of 3 cubic feet of air per second for one second, (essentially pulsed DC), to 22Khz ± 2dB. The Screen alone, (not biamplified with electronic crossover and panel segment subwoofer, or Linear Actuator V-Driver Subwoofer) 75 Hz to 22Khz ± 2dB. Overall Dimensions: Total screen, frame and legs) 96 inches high, 96 inches wide, 3.75 inches deep. Total driven diaphragm surface: 15 square feet, (not including subwoofer). Weight: 268 pounds Note: The Screen may be supplied with screens as chosen by the customer. One available configuration is with a silk screen print, or pull down art tapestry, so that when the screen is not in use as a front projection video surface, it may stand essentially as a work of fine tapestry art. Custom silks and fabrics are available.
The Planar Transducer is designed as a large planar source device, very nearly all of the surface of which is a direct radiating, forward facing transducer thus comprising nearly fifteen square feet of surface. The sound source is mounted on the reflecting plane of the wall itself so that there is essentially no path length difference between the front and back sides of the bipolar diaphragm, thus the source radiates into a hemisphere of free space, a half space or 2pi sr. Because the free space is a half space or hemisphere at low frequencies, where the sound source is truly omnidirectional, the sound level is elevated by 6 decibels, which compensate for a falling frequency response at low frequencies.
