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 ę—ished 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.

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.
