Specification Tools

Technical Data SoundTube Entertainment strives to provide complete and effective technical information and data to dealers, engineers and designers. All data are available 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 102 mm (4 in) polypropylene woofer and one 25 mm (1 in) convex aluminum tweeter with Ferro-Fluid cooling. Performance specifications of a typical production unit shall be as follows: Useable frequency response shall extend to 73 Hz (-10 dB, full space, no external equalization). Measured sensitivity (2.83 Volt input, 1 meter) shall be at least 88.5 dB. The speaker shall have a nominal impedance of 4 Ohms and be available for 25, 70.7 & 100 Volt modes with voice coil/4 Ohm direct. The frequency dividing network shall have a crossover frequency of 2.27 kHz with slopes of 12 dB per octave (2nd order) for both low and high pass filters. Rated power capacity shall be at least 20 Watts continuous power (RMS) and conform to EIA-426-B testing. Maximum continuous output at 1 meter shall be 98 dB. The low-frequency transducer shall have a polypropylene cone with butyl rubber sur-round. The high-frequency transducer shall
