Sonance IS8T

Brian Long

Introduction

Invisible Speakers represent the peak of Sonance’s Designed to Disappear strategy. High frequencies are delivered using Sonance Motion Flex Technology, which features a Wave Flex Drive Unit with a bending wave diaphragm and a 1.75-inch (44mm) voice coil. Low frequencies are produced by an Air Flex Woofer that uses an air pulse diaphragm powered by an 8-inch (203mm) carbon fiber woofer.

Architectural Specifications
The loudspeaker shall be of the two-way type comprising a single cabinet that is designed to install flush into a ceiling or wall and be finished over with up to 1/8” (3mm) of flexible material to provide a completely invisible installation. It shall feature Motion Flex Technology, consisting of a Wave Flex Drive Unit with a 29in (188cm) bending wave diaphragm utilizing a 1.75” (44mm) voicecoil, combined with an Air Flex Woofer with a 191in² (1234cm) air pulse diaphragm utilizing an 8” (203mm) carbon fiber woofer. Frequency range shall be 40Hz – 30KHz (-3dB). Total power handling shall be 160 Watts RMS program. Sensitivity measured with 2.83 volts input at 1 meter on axis averaged between 40Hz – 30KHz shall be 86dB. The unit shall be supplied with a line matching laminated core transformer suitable for 100 volt or 70 volt with rear-mounted control allowing user selectable power taps of 60W, 30W, 15W and 7.5W (70V) and a 6 Ohm bypass. Protection shall be provided by two independent, self-resetting poly switches. It shall provide 170 degrees of dispersion up to 10kHz. The back can shall be constructed from metal. The speaker shall be suitable for use in air handling spaces per UL2043, NFPA90 and NFPA70 S7232 as well as UL1480A, UL Rated signaling speaker. Wire shall be terminated in an enclosed area on the rear of the back can via a knock-out with internal strain relief. It shall feature the proprietary Sonance D.I.S.C. System, allowing the installer to accurately measure the thickness of topping material over the diaphragm to ensure optimum sonic performance. External dimensions shall be 16.10” Wide x 24.13” High x 3.86” Depth (409mm x 613mm x 98mm). The total enclosure shall weigh 25.24 lbs. (11.45 kg) per unit. The loudspeaker shall be the Sonance Invisible Series IS8T. No other system shall be acceptable unless the above combined performance specifications are equaled or exceeded.
