Technical Data and

Specification Tools

Technical Data

SoundTube Entertainment strives to provide complete and effective technical information and data to dealers, engi- neers and designers. All data are avail- able from SoundTube Entertainment or at www.soundtube.com.

Data Acquisition

All performance data acquired at SoundTube’s Technical Measurement Center (TMC) are analyzed using a vari-

ety of standard measurement techniques, 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 propri- etary modeling software. 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 203

mm(8 in) low-frequency transducer and a high frequency transducer with a 1” exit and a frequency-dividing network installed in a ported enclosure. The low- frequency voice coil diameter shall be 34 mm (1.36 in).

The performance specifications of a typical production unit shall be as follows: Useable frequency response shall extend from 63 Hz – 22 kHz (-10 dB, no external equalization). Measured sensitivity (2.83 Volt input, 1 meter) shall be at least 94 dB. The speaker shall have a nominal

impedance of 8 Ohms and be available for 25/70.7/100 Volt modes with a voice coil/8 Ohm direct. The frequency-dividing net- work shall have a crossover frequency of 2.4 kHz with a slope of 12 dB per octave (2nd order). Rated power capacity shall be at least 125 Watts continuous power (RMS), and shall conform to EIA-426-B testing. Maxi- mum continuous output at 1 meter shall be 115 dB.

The low-frequency transducer shall have a treated fiber cone and cloth surround.

Installation for the HP890i shall be by 10’ aircraft cable affixed to the speaker chassis via hook. For seismic and safety redundancy, a secondary aircraft cable shall be included and shall attach to the speaker chassis via hook and cable system. The external wiring shall be a 4-pin 5 mm Euroblock connector for 8 Ohm or distributed systems and shall accept from 10 – 22 gauge wire. The system shall be for indoor and outdoor applications and have a weather-resistant terminal boot covering all wire connections.

The enclosure shall be constructed of injection-molded, glass reinforced ABS. The grille shall be constructed of iridite-plated, powder-coated steel for lasting performance
