	Technical Information for System Engineers

Applications

Designed for indoor & outdoor back- ground to mid-level SPL applications, the RS500i includes a single-point mounting system for rapid open-ceiling installations. The 100° broad dispersion pattern (55 Hz – 10 kHz) and high sensi- tivity (88.5 dB 1W/1M) make the RS500i speaker ideal for music & paging appli- cations in retail, grocery stores, restau- rants, hotels, casinos, museums, trade shows & conference rooms. For applica- tions where additional bass is required, SoundTube’s RS801i 8” subwoofer pro- vides bass down to 40 Hz.

BroadBeam® Wide

Dispersion Technology

More than 3 years in development, SoundTube’s proprietary BroadBeam® technology incorporates a high-fre- quency waveguide mated to a 1” convex aluminum tweeter. The BroadBeam® high-frequency waveguide delivers a consistent 100° dispersion pattern across the upper registers of the frequency spectrum (up to 10 kHz, EASE™ docu- mented). The result is an audio system with fewer speakers, reduced power

needs, shorter installation time and cost savings on shipping & labor.

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.

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 TEF20/ Outline/EASE™ interface.
