Patented SoundTube

Technologies

SoundTube Entertainment and the MSE Audio Group constantly develop new technologies which enhance audio product performance. SoundTube Enter- tainment innovations are protected by multiple U.S. & 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 effective techni- cal information and data to dealers, engineers and designers. All data are available from SoundTube Entertain- ment or at www.soundtube.com and includes EASE™ Data – 3-D polar plots and SoundTubeSPEC™ – Proprietary SoundTube speaker placement software.

Independent Data Acquisition

and Verification

All data for SoundTube speakers are 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 a 133 mm (5.25 in) low-frequency transducer and a 25 mm (1 in) high- frequency transducer with a frequency- dividing network installed in a sealed enclosure. The low-frequency trans- ducer shall have a polypropylene cone with a butyl rubber surround. The high-frequency transducer shall be constructed of aluminum with a pro- prietary BroadBeam® waveguide.

The low-frequency voice coil diameter shall be 25.4 mm (1 in).

Performance specifications of a typical production unit shall be as follows: Useable frequency response shall extend from 69 Hz – 22 kHz (-10 dB, half space, no external equaliza- tion). Measured sensitivity (2.83 Volt, 1 meter) shall be at least 87.5 dB. The speaker shall have a nominal imped- ance of 8 Ohms and shall be available for 25/70.7/100 Volt modes with voice

coil/8 Ohm direct. The frequency- dividing network shall have a cross- over frequency of 3 kHz with slopes of 12 dB per octave (second order) for both low and high-pass filters. Rated power capacity shall be at least 75 Watts continuous power (RMS) and conform to EIA-426-B testing. Maxi- mum continuous output at 1 meter shall be 106.5 dB.

Installation for the IW500b shall be by 4-screw, constant-tension optimally engineered mounting assembly. The external wiring input connector shall be by hard wired leads for 8 Ohm or distributed systems.

The grille shall be constructed of powder-coated steel for lasting per- formance and attach via pressure fit directly to the ABS bezel. The backcan shall be constructed of drawn steel.

The system shall be the SoundTube IW500b with mounting hardware for both low & high impedance applica- tions.
