Independent Data Acquisition & Verification
All data for SoundTube speakers is independently collected from and veri- fied by NWAA Labs (www.nwaalabs. com) using their proprietary MACH testing system. All data is collected and analysed 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 shall consist of one
102mm (4 in) low-frequency trans- ducer and one 19 mm ( 0.75 in) high- frequency transducer with a frequency dividing network installed in a sealed enclosure. The low-frequency voice coil diameter shall be 13 mm (0.50 in). The low-frequency transducer shall have a treated fiber cone material with cloth surround. The high-frequency transducer shall be constructed of silk material using a balanced-dome con- figuration.
Performance specifications of a typi- cal production unit shall be as follows: Usable frequency range shall extend from 120 Hz - 22 kHz, -10 dB. The loudspeaker shall be available with selectable 25/70.7/100 Volt and 16 Ohm/voice coil direct tap switch. The frequency dividing network shall have a crossover frequency of 5.0 kHz. Rated power capacity of the compo- nents and network shall be at least 20 Watts continuous RMS power and con- form to EIA-426-B testing. Maximum continuous output at 1 meter shall be at least 100.5 dB.
The backcan shall be constructed of galvanized steel with an ABS plastic baffle. The grille shall be constructed of painted steel. Shipped complete with UL-listed flex conduit clamp, color coded tile bridge (to match color- coded backcan), grille, wire nuts, cut-out template and paint shield, the integrated CM42-EZs in-ceiling speaker is engineered for high per- formance and rapid installation in plenum spaces. The CM42-EZs incor- porates a secondary attachment point
for added security, or where required by code.
Installation for the CM42-EZs shall be by 2-screw blind-mount constant-ten- sion winged assembly and shall attach to ceiling thicknesses ranging from
0.00in to 1.50 in. The external wiring shall be hardwired using wire nuts accepting up to three 18-gauge wires.
The CM42-EZs is factory preset to the 20 Watt setting in the 70.7 Volt mode with a tap switch located on the front baffle. The system shall be the SoundTube CM42-EZs for both low & high impedance applications.
