Data Acquisition

All performance data acquired at SoundTube’s Technical Measurement Center (TMC) are analyzed using a variety of standard measurement techniques, includ- ing Maximum Length Sequence (MLS) and Time Delay Spectrometry (TDS). Perfor- mance, development and data acquisitions tools include: Gold Line TEF 20 Suite, CLIO, LMS, LEAP, and proprietary model- ing software.

Architectural Specifications

The loudspeaker shall consist of a 133 mm (5.25 in) low-frequency transducer and a 25

mm(1.0 in) high-frequency transducer with a frequency-dividing network installed in the enclosure. The low-frequency voice coil diameter shall be 25 mm (1.0 in). Sound waves from the low- and high-frequency drivers shall be reflected from a 781 mm (30.75 in) Dual-Parabolic™ sound dome.

Performance specifications of a typical production unit shall be as follows: Usable frequency response shall extend from

95 Hz – 20 kHz. The loudspeaker shall be available in either voice coil/4 Ohm direct or 70.7/100 Volt models, and equipped with a corrosion-resistant binding post for pre-selected impedance modes. Taps should be nominally 4 W @ 70.7 V (8 W

@100 V), 8 W @ 70.7 V (16 W @ 100 V),

16 W @ 70.7 V (32 W @ 100 V), and 32 W @ 70.7 V (tap position not used @ 100 V). Transformer options are factory preset at 8 Watt, unless otherwise specified at time of order. The frequency-dividing network shall have a crossover frequency of 5 kHz. Rated power capacity of the components and network shall be at least 50 Watts conti- nous RMS.
