	Preliminary Technical Information for System Engineers

Data Acquisition

All performance data acquired at

SoundTube’s Technical Measurement Center (TMC) are analyzed using a variety of standard measurement tech- niques, including Measured Length Sequence (MLS) and Time Delay Spectrometry (TDS). Performance, development and data acquisition tools include: Gold Line TEF 20, CLIO, LMS, LEAP, and proprietary modeling soft- ware. EASE™ data are acquired through an automated TEF 20/Outline/EASE™ interface.

EASE™ Data – 3-D polar plots.

SoundTubeSPEC™ – Proprietary SoundTube speaker placement software.

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 ported enclosure. The low-frequency voice coil diameter shall be 25 mm (1 in).

Performance specifications of a typi- cal production unit shall be as follows:

Useable frequency response shall extend from 61 Hz – 22 kHz (-10 dB, half space, no external equalization). Measured sensitivity (2.83 Volt input, 1 meter) shall be at least 89.5 dB. The speaker shall have a nominal impedance 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 crossover frequency of 3 kHz with a slope of 12 dB per octave (second order) for the high-pass filter. Rated power capacity shall be at least

80 Watts continuous power (RMS), and conforms to EIA-426-B testing. Maxi- mum continuous output at 1 meter shall be 108.5 dB.

The low-frequency transducer shall have a polypropylene cone with butyl rubber surround. The high-frequency transducer shall be constructed of alu- minum material and incorporate a high- SPL horn.

Installation for the SM590i shall be by proprietary & corrosion-resis- tant captured-ball mounting system. SoundTube’s tool-free captured-ball mounting system incorporates a locking zinc alloy lever attaching to a cast-alu-

minum ball. For seismic and safety redun- dancy, a secondary aircraft cable shall

be included and attached to the speaker chassis via ¼ - 20 bolt. The external wir- ing input connector shall be a 4-pin, 5 mm Euroblock for 8 Ohm or distributed sys- tems and shall accept from 10 – 22 gauge wire.

The system shall be for indoor/outdoor applications and shall have a weather- resistant terminal boot covering all wire connectors. The enclosure shall be constructed of injection-molded, glass- reinforced ABS. The grille shall be con- structed of iridite-plated, powder-coated aluminum for lasting performance.

Overall cabinet dimensions shall be no more than 316.9 mm (12.48 in) in height by

216.6mm (8.53 in) in width by 305.1 mm (12.01 in) in depth (including SM bracket). The SM590i shall include mounting hard- ware, Euroblock connector & terminal weather boot.

The system shall be the SoundTube SM590i with mounting hardware for both low and high impedance applications.
