SM500i Surface-Mount Speaker

Technical Information for System Engineers

proprietary captured ball mount- ing system with security screw for theft prevention. The full frequency dispersion pattern (45 Hz – 10 kHz, EASE™ documented) and high sensitiv- ity (88.5 dB 1W/1M) make the SM500i surface-mount speaker ideal for music

&paging in retail, amusement, restau- rant, airports, hotels, schools and casi- nos. For applications where additional bass is required, SoundTube’s RS801i subwoofer provides 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 metal tweeter. BroadBeam® wave- guide technology delivers a consistent BroadBeam® 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

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 Cen- ter (TMC) are analyzed using a variety 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.
