Audibax Horn 20T - 6.5" 20W Unidirectional Projector Speaker for 100V Line

Audibax Horn 20T - 6.5" 20W Unidirectional Projector Speaker for 100V Line

The Audibax Horn 20T is an exponential loudspeaker designed for public address and distributed sound systems using 100V lines. It features a 6.5" transducer and an internal transformer with selectable 20/10/5W taps, allowing for power adjustment at each point without recalculating the entire installation. With a frequency response of 100 Hz to 17 kHz and a sensitivity of 92 dB (1 W/1 m), it delivers excellent speech and announcement intelligibility, ideal for environments such as supermarkets, parking lots, corridors, warehouses, and transit areas. Its unidirectional projector design focuses energy towards the listening area to reduce reverberation and improve clarity. The white finish and mounting bracket facilitate clean wall integration.

Main features

• Exponential format (unidirectional projector) to prioritize the clarity of voice and announcements.
• 6.5" transducer with integrated 100V line transformer.
• Selectable power: 20 / 10 / 5 W (100V sockets) to balance zones without changing wiring.
• Frequency response: 100 Hz – 17 kHz; SPL: 92 dB (1 W/1 m).
• Wall mount with directed sound projection.
• Compact dimensions: 170 mm (diameter) × 252 mm (depth). White color.
• Parallel connection of multiple units in 100V systems to cover large areas.

Product benefits

• Superior intelligibility in ads and messages thanks to the unidirectional horn pattern.
• Scalability : When working at 100V, more speakers can be added with long cable runs without significant losses.
• Flexibility of adjustment per socket (20/10/5 W) to adapt each zone to the required sound level.
• Easy wall mounting and minimal maintenance for continuous use in commercial facilities.
• Discreet white finish to blend into hallways, low ceilings and public spaces.

Use cases

• Public address systems in supermarkets and stores for announcements and light background music.
• Parking lots , corridors and common areas in buildings and fairgrounds.
• Logistics centers and industrial buildings for internal communications.
• Schools , sports centers and civic centers with 100V systems.

Frequently Asked Questions

Do you need a 100V amplifier?
Yes. The Horn 20T is designed to operate exclusively on a 100V line . It should not be powered on a low impedance supply.

Can I combine multiple speakers on the same line?
Yes. In 100V systems, they are connected in parallel and the selected power ratings of each unit are added together to size the amplifier.

Is it suitable for music?
It is optimized for voice and alerts ; it can play light ambient music within its working range.

Does it include a mounting bracket?
Includes wall mounting hardware and terminals for connection to a 100V line.

Installation and connection

• Select the power input (20/10/5 W) on the transformer according to the level required in the area.
• Connect to the 100V and 0V lines , respecting the polarity. To cover large areas, connect several units in parallel.
• Do not power the 8 Ω speaker directly from low impedance stages; always use it through its 100V transformer.
