Soundtube HP129A 12" Hanging Speaker with Transformer

SoundTube HP129A 12" Hanging Speaker with Transformer

The SoundTube HP129A is a high-performance 12-inch hanging pendant speaker engineered for demanding commercial sound reinforcement and public address environments. Featuring SoundTube’s patented BroadBeam Ring™ waveguide technology, the HP129A delivers exceptionally smooth frequency response and maximum SPL across the full audio spectrum — making it a preferred choice for large open spaces that require authoritative, intelligible sound. Its ported ABS Glass Fiber Reinforced enclosure extends bass response to 73 Hz (-10 dB), providing depth and clarity that conventional pendant speakers cannot match. Pair it with your 25V, 70.7V, or 100V distributed system via the integrated multi-tap transformer, or bypass the transformer entirely for direct 8-ohm operation.

Product Description

The HP129A is designed for installations where ceiling heights and acoustic challenges demand a powerful, reliable solution. A 12-inch treated fiber cone woofer with a cloth surround and a 1.375-inch Mylar compression driver with waveguide deliver a 97 dB sensitivity rating — reducing amplifier requirements and operating costs significantly. The 4th-order crossover network at 2.2 kHz ensures clean driver handoff, while the 90° coverage angle (±6 dB at 2 kHz) provides uniform sound distribution across wide seating areas. Power handling reaches 150W RMS continuous and 300W program, giving integrators substantial headroom. A convenient five-position rotary tap switch supports 25V, 70.7V, and 100V distributed audio systems, plus transformer bypass for direct 8-ohm connection. Installation is straightforward: the speaker includes hanging hardware, a safety cable, a Euroblock connector, and a terminal weather boot, with UL 1480 (UEAY) and UL 2239 (hanging cable) listings providing compliance assurance. The powder-coated steel grille is available in the included black finish or optionally in white. Available in Black (HP129A-BK) and White (HP129A-WH), the HP129A integrates seamlessly into virtually any architectural finish.

Key Features

• BroadBeam Ring™ Waveguide — Patented SoundTube technology ensures smooth off-axis response and maximum SPL throughout the coverage area.
• 12" Treated Fiber Cone Woofer — High-excursion driver with treated cloth surround delivers robust low-frequency extension to 73 Hz (-10 dB).
• 97 dB Sensitivity — High efficiency reduces amplifier load and system operating costs in large distributed audio deployments.
• Multi-Voltage Transformer — Five-position rotary tap switch supports 25V, 70.7V, and 100V distributed systems; bypass position enables direct 8-ohm connection.
• 150W RMS / 300W Program Power — Substantial power handling ensures clean, undistorted output even at demanding SPL levels.
• 90° Coverage Angle — Wide, consistent coverage pattern reduces the number of speakers required in large rooms.
• 4th-Order Crossover at 2.2 kHz — Steep crossover slopes minimize driver overlap and maximize clarity.
• UL 1480 & UL 2239 Listed — Meets fire-safety and hanging cable standards required in commercial and public assembly venues.
• Ported ABS Enclosure — Glass fiber reinforced ABS with injection-molded construction; ported design extends bass response without a separate subwoofer.
• Included Hardware — Hanging hardware, safety cable, Euroblock connector, and terminal weather boot included for fast, code-compliant installation.

Typical Applications

• Houses of Worship — High-ceiling sanctuaries require the long throw and wide coverage the HP129A provides.
• Convention Centers & Ballrooms — Large open spaces benefit from the speaker’s 97 dB efficiency and 300W program power.
• Gymnasiums & Sports Facilities — Durable enclosure and high-SPL output suit reverberant athletic environments.
• Retail Big Box & Warehouses — 70.7V/100V transformer compatibility integrates directly into existing distributed systems.
• Airports & Transit Terminals — UL listings and robust construction meet the reliability demands of public infrastructure.
• Performing Arts & Multipurpose Venues — High sensitivity and wide dynamic range handle both speech and music reinforcement.

Technical Specifications

Frequently Asked Questions

Q: What voltage systems is the HP129A compatible with?
A: The HP129A includes a built-in multi-tap transformer supporting 25V, 70.7V, and 100V distributed audio systems. A bypass position on the rotary tap switch enables direct 8-ohm connection for systems that do not use a distributed voltage architecture.

Q: Is the HP129A suitable for outdoor or covered outdoor use?
A: The HP129A is designed for indoor or covered environments. The enclosure is ABS glass fiber reinforced and the included terminal weather boot provides moisture protection at the connector, but the speaker is not rated for direct weather exposure. For outdoor applications, SoundTube offers dedicated weather-rated product lines.

Q: What hanging hardware is included?
A: Each HP129A ships with hanging hardware, a UL 2239-compliant safety cable, a Euroblock connector, and a terminal weather boot. Optional hanging kits in 10-foot, 20-foot, and 50-foot lengths are available separately.

Q: Can I add a surface mount bracket to the HP129A instead of hanging it?
A: Yes. SoundTube offers a Black Surface Mount Bracket (AC-HP-SM129-BK) as an optional accessory, allowing the HP129A to be bracket-mounted to a wall or truss in addition to its standard pendant configuration.

Q: What amplifier power is recommended for the HP129A?
A: With a sensitivity of 97 dB (1W/1M), the HP129A is highly efficient and requires significantly less amplifier power than lower-sensitivity speakers to achieve the same SPL. For background music at moderate levels, a 25W tap is often sufficient; for high-output PA applications, use the 150W tap with an appropriately rated amplifier.

Q: What certifications does the HP129A carry?
A: The HP129A is CE, RoHS, UL1480A, and UL2239 certified, meeting requirements for commercial, institutional, and public assembly installations in North America and Europe.

Q: Is a black grille available?
A: Yes. A Black Grille (GRL-HP129-BK) is available as an optional accessory for installations requiring an all-black aesthetic.
