Ȋ Ultra-low proęle ZeroReĚection™ ABS enclosure (4.35 inch diameter by 4.35 inch height without stabilizing arm). Ȋ Corrosion-resistant, powder-coated aluminum grille. Ȋ UL 1480 (UEAY) planned. Ȋ High quality black or white paint ęish. Ȋ Included accessories: Mounting element, cover plate, 10Ğ speaker signal/hanging cable. Description TheRS31-EZ is a premium full-range 3 inch pendant-mount speaker, with overall dimensions smaller than a 4 inch sphere. The RS31-EZ incorporates a 10 Ğ length of speaker signal/hanging cable for on-ceiling applications. Components have been weatherized for indoor/outdoor applications. TheRS31-EZ is an 8 ohm speaker without transformer. The speaker utilize the all-inone ceiling mount system designed to retroęt in most j-boxes. Cover plate is included to hide mounting element and hold excess signal/hanging cable. Applications Engineered for rapid installation and low proęle mounting for smaller venues, the RS31-EZ is ideal for ęished ceiling applications in retail, restaurants, conference rooms, patio areas, educational facilities or any seĴing where full-range intelligibility, unobtrusive design and installation ease are paramount. For additional bass response down to 41 Hz (- 10 dB), the SM1001p powered 10-inch subwoofer may be incorporated. RS31-EZ On-Ceiling Speaker Preliminary Technical Information for System Engineers Patented SoundTube Technologies SoundTube Entertainment and the MSE Audio Group constantly develop new technologies which enhance audio product performance. SoundTube Entertainment innovations are protected by multiple U.S. and international patents, which explicitly cover SoundTube dome, enclosure and dispersion technologies. The MSE Audio Group actively defends its patents in order to protect SoundTube resellers and end-users. Technical Data and Speciﬁcation Tools Technical Data SoundTube Entertainment strives to provide complete and eěective technical information and data to dealers, engineers and designers. All data are available from SoundTube Entertainment or at www.soundtube.com. Technical data and downloads include: EASE™ data – 3-D polar plots. EASE™ Address – 2-D modeling for distributed systems Autodesk® Revit® soĞware Tech Sheets – Technical information and architectural specs for system engineers SoundTubeSPEC™ – Proprietary speaker placement soĞware Performance specięcations for a typical production unit shall be as follows: Useable frequency response shall extend from 120 Hz – 22 kHz (- 10 dB). Measured sensitivity (2.83 volt input, 1 meter) shall be at least 85.0 dB. Rated power capacity shall be at least 20 waĴs continuous (RMS) and conform to EIA-426-B. Maximum continuous power output at 1 meter shall be 98 dB. Installation shall be by mounting element designed to retro-ęt in most junction boxes. The speaker will hang via 10 foot signal/hanging cable (included). Cover plate is inculded to store excess signal/ hanging cable as it is screwed into place, concealing the mounting element and junction box. The speaker utilizes weatherized components for indoor and outdoor applications. External wiring shall be by low-proęle screw terminal and shall accept from 10 – 22-gauge wire. The enclosure shall be constructed of injection-molded, ABS. The grille shall be constructed of powder-coated aluminum for lasting performance and aĜx to the speaker baĝe via pressure ęt. Overall cabinet dimensions shall be no more than 110.5 mm (4.35 in.) in height by 110.5 mm (4.35 in.) in diameter. The unit height with stabilizing arm shall be no more than 139.7 mm (5.5 in.). The system shall be the RS31-EZ for low-impedance applications. Acquisition and Veriﬁcation All data for SoundTube speakers are independently collected from and verięed by NWAA Labs (www.nwaalabs. com) using their proprietary MACH testing system. All data are collected and analyzed according to ASTM, ISO and AES standards using EASERA, TEF and MLSSA. Full balloon data including both phase and magnitude is compiled into a variety of formats including EASE 4.x, GLL and CLF. Architectural Speciﬁcations The loudspeaker transducer shall consist of one full-range 76.2 mm (3.0 in.) polypropylene cone with butyl rubber surround.
