Beyma TD-385 Constant Directivity Horn
The Beyma TD-385 is a constant directivity horn designed for use with 1.4” throat compression drivers. Its square-format design makes integration into loudspeaker enclosures both flexible and convenient, especially where symmetrical installation is needed. The horn is made from cast aluminum to ensure mechanical stability and resonance-free operation, even at high SPLs. Engineered for natural and neutral sound reproduction, the TD-385 offers consistent on- and off-axis performance with a horizontal beamwidth of 80º and vertical beamwidth of 50º. This pattern is maintained across a broad frequency range (1–20 kHz horizontally and 1.6–20 kHz vertically), ensuring effective coverage for a variety of applications from stage monitoring to front-of-house systems. The TD-385 features a directivity factor (Q) of 12.4 and a directivity index (DI) of 10.5 dB, providing strong acoustic control. It supports a minimum cutoff frequency of 800 Hz, making it suitable for drivers with low crossover points. With dimensions of 235 x 235 x 120 mm and cutout dimensions of 204 x 202 mm, the TD-385 mounts via four screws on a 101.6 mm diameter bolt circle. At a net weight of 1.2 kg, this horn offers a great balance of durability and ease of installation, making it a trusted component in professional loudspeaker designs.
