The BRT-15 is a high performance compact cabinet which is ideally suited to both portable use and fixed installation, offering extremely flexible mounting options including a top hat and both horizontal and vertical mounting yokes, rotatable horns, integrated handle and internal passive crossover designed to match the voicing of other products in the series, all achieving a flat, linear frequency response.

The discreet design with reticulated foam front and acrylic textured paint finish and multiple integrated fixing points achieves a high class look suitable for any application.

Designed with an OHM 15” proprietary 600 W, 8 Ohm woofer and 1.5” compression driver, the internal passive crossover ensures a linear, usable frequency response of 52 Hz to 22 kHz (-10 dB) across 60°x 40° dispersion with rotatable horn. A maximum SPL of 133 dB (peak).

Sharing voicing characteristics with the rest of the BR series allowing them to be used simultaneously, keeping a consistent tone.

Mounting options include integrated aluminium top-hat and horizontal cradle fixing points for use with the BRC-15 Horizontal, BRC-15 Vertical Yoke and rear mounted pan and tilt bracket PTL. Other fixings can be used with this cabinet such as the fixed large wall bracket (LWB) and pan and tilt wall bracket (LWB-PT). This product is also Powerdrive compatible with the type 100 plate products.

The rear cast aluminium connection plate has two 4 pin speakON® connectors fitted as standard, one input and one link. The speakON® connectors are wired on pins +1-1, with pass through of pins +2-2.
