L-TRONIK T-720A - Exponential horn speaker made of ABS and IP65 weatherproof

L-TRONIK T-720A - IP66 ABS exponential horn for PA systems 70/100 V (15 W RMS)

The L-TRONIK T-720A is an exponential horn loudspeaker for outdoor PA systems , made of white ABS with a metal U-shaped handle/bracket for easy orientation and anchoring. Its weatherproof design with IP66 protection rating allows it to operate in demanding environments (dust and powerful water jets) such as industrial buildings, parking lots, courtyards, sports venues, warehouses, and outdoor emergency announcements.

It features a 70/100 V line transformer with multiple power taps to adapt the level to the area and wire multiple units in parallel with reduced losses. The frequency response of 300 Hz to 13 kHz (-10 dB) has been optimized for voice intelligibility and clear messages in noisy environments, while its sensitivity of 103 dB (1 W/1 m) offers high performance with lower power consumption from the amplifier. With dimensions of 282 × 210 × 290 mm and weight of 2.1 kg , it combines a compact format and sufficient sound pressure for medium-to-long-distance coverage.

For installation, it features a multi-wire cable connection and tap selection on the cable harness itself; it is recommended to use a watertight connection and outdoor-rated cable. Its rated power is 15 W RMS (up to 60 W peak ), with 7.5 W / 15 W (70 V) and 15 W / 30 W (100 V) taps to customize the system to your specific scenario.

Product benefits

• Clarity and intelligibility in warnings, evacuations, and critical messages thanks to its directivity.
• Scalability in distributed installations: multiple loudspeakers in parallel over 70/100 V.
• Lower maintenance due to its sealed construction and UV and moisture resistant materials.
• Efficiency : High sensitivity reduces power demand on the amplifier.
• Versatile installation on walls, pillars or structures, with precise orientation using the metal U.

Use cases

• General and emergency notices in industry , logistics and parking .
• Sports venues , school playgrounds and open areas with high traffic.
• Commercial exteriors , stations, platforms and pedestrian access.
• Perimeter PA and messages on large outdoor surfaces.

Frequently Asked Questions

• Is it submersible? No. Its protection is IP66 (dust and powerful jets); it is not designed for immersion.
• Can I use it in existing 100V systems? Yes, select the 15W or 30W outlet based on coverage and power budget.
• Can it be used on 8 Ω? It is not designed for direct low impedance; it works via a 70/100 V line .
• Which cable should I use? Outdoor cable (UV-resistant) and sealed splices in suitable boxes or cable glands.
