Soundtube RS800I 8" Hanging Speaker with a BroadBeam Tweeter

SoundTube RS800I 8" Hanging Speaker with BroadBeam® Tweeter

The SoundTube RS800I is the flagship RSi Original Pendant hanging speaker, delivering commercial-grade audio performance in one of the most acoustically engineered pendant enclosures available. Its 8-inch polypropylene cone woofer with butyl-rubber surround is mounted to a proprietary cast-aluminum baffle and heat sink, then mated with a 1-inch convex aluminum tweeter featuring FerroFluid cooling and SoundTube’s proprietary BroadBeam® waveguide technology. The BroadBeam waveguide system maintains a consistent 115° coverage angle from 2 to 10 kHz (independently verified), ensuring that every seat in a large atrium, shopping center, or airport concourse receives the same balanced, articulate sound without the narrow high-frequency beam that plagues conventional dome tweeters in pendant enclosures.

The ZeroReflection™ enclosure technology eliminates internal standing waves that degrade clarity, while the ported design extends low-frequency response to a measured 58 Hz (±10 dB)—deep enough to reproduce bass content convincingly without a supplemental subwoofer in most commercial applications. The six-position rotary tap switch provides instant field selection between 8Ω direct, and 25V/70.7V/100V transformer settings (9W, 66W, and 66W maximum taps respectively), eliminating the need to stock multiple SKUs for different voltage configurations. Driver protection circuitry safeguards the tweeter from transient clipping events. SpeedClamp™ self-locking cable grips on the included galvanized steel hanging cables allow fast, one-person installation without climbing back up to reset the cable length. The RS800I is certified to CE, MIL Spec, RoHS, UL1480A, and UL2239 standards. Available in both black and white finishes.

Key Features

• BroadBeam® Waveguide Tweeter — Maintains a consistent 115° coverage angle from 2–10 kHz, independently verified, ensuring even high-frequency distribution across wide listening areas.
• 8" Polypropylene Woofer with Cast-Aluminum Baffle — Rigid aluminum baffle and heat sink dissipate thermal energy during high-output operation for long-term driver reliability.
• ZeroReflection™ Enclosure Technology — Patented internal geometry eliminates standing waves that cause coloration and intelligibility loss in conventional pendant enclosures.
• Ported Open-Ceiling Enclosure — Extended bass response to 58 Hz (±10 dB) satisfies commercial audio bandwidth requirements without a supplemental subwoofer in many spaces.
• Six-Position Rotary Tap Switch — Field-selectable 8Ω direct bypass plus 25V/70.7V/100V transformer taps (max 9W/66W/66W) in a single SKU, simplifying inventory management.
• 125 W RMS / 250 W Program Power — High-power handling supports large venue deployments where extended listening coverage demands sustained high-SPL output.
• SpeedClamp™ Self-Locking Cable Grip — Enables fast, one-person cable installation and height adjustment on galvanized steel hanging cables without additional tools.
• Driver Protection Circuitry — Onboard protection shields the tweeter from amplifier clipping and transient overload events in real-world commercial installations.
• CE, MIL Spec, UL1480A & UL2239 Certified — Meets demanding commercial safety and durability certifications for permanent commercial building installation.

Typical Applications

• Shopping malls, airport concourses, and large-format retail stores with high ceilings
• Hotel atriums, lobby spaces, and convention center pre-function areas
• Restaurant and food-court areas requiring high-SPL background music with speech intelligibility
• Sports and entertainment facilities where consistent coverage across large floor areas is required
• Houses of worship with open sanctuary plans and high vaulted ceilings
• Corporate lobbies, open-office environments, and transit terminals

Frequently Asked Questions

Q: What makes BroadBeam® different from a standard dome tweeter in a pendant speaker?
A: A conventional dome tweeter narrows its dispersion dramatically above 5 kHz, creating a narrow high-frequency beam directly below the speaker. BroadBeam®’s proprietary waveguide maintains a consistent 115° angle from 2 to 10 kHz, so customers seated or standing anywhere within the coverage zone hear the same high-frequency response.

Q: Can the RS800I be used in a 70V distributed system?
A: Yes. The six-position rotary tap switch provides 70.7V operation at up to 66 W, making it directly compatible with 70V commercial amplifier outputs. It also supports 100V (66 W max) and 25V (9 W max) operation from the same switch.

Q: How long are the included hanging cables?
A: The standard installation kit includes hanging hardware and safety cables. Optional 10-foot, 20-foot, and 50-foot extension cables (AC-RS-HH-10/20/50) are available for high-ceiling applications.

Q: Is the RS800I available in white?
A: Yes. The RS800I is available in both black (RS800I-BK) and white (RS800I-WH) finishes. Both share identical acoustic specifications.

Q: Does the RS800I require a separate crossover?
A: No. A fully passive 2nd-order crossover is built into the enclosure, dividing the signal between the woofer and BroadBeam tweeter at 3.0 kHz.

Q: What ceiling height range is the RS800I designed for?
A: The RS800I performs optimally in ceilings ranging from approximately 10 to 30 feet. For ceilings above 30 feet, SoundTube’s HPi High Ceiling Pendant series is recommended. Creation Networks can model coverage for your specific space—contact us for a free consultation.

Q: Is a surface-mount bracket available?
A: Yes. The optional AC-RS-SM8-BK (black) surface-mount bracket allows the RS800I to be mounted directly to a flat ceiling surface without hanging cables.
