FRX 15i is a compact, powerful bi-amplified 2-way constant curvature loudspeaker, optimized for medium throw, high SPL installation applications. FRX 15i is a uniquely versatile building block for systems ranging from single top pole mounts to left/right, central cluster or in the round setups. Typically used in horizontal ground stack configurations, FRX 15i can also be flown, allowing it to adapt to the needs of the venue. The adjustable 80×30° AF horn can be configured quickly without the need for tools.

Our proprietary X-Comb DSP technology eliminates comb effects, ensuring perfect coupling between FRX 15i cabinets and creating a coherent wavefront at any location. The enclosure houses a 1.4’’ diaphragm compression driver loaded with a 15’’ neodymium low-frequency transducer and offers two distinct directivity plans.

FRX 15i can be quickly deployed in any configuration when used with AUDIOFOCUS A Series amplifiers with integral DSP and dedicated presets. Armonia presets are also available for Powersoft amplifiers.

FRX 15i is built with pride in Belgium and coated in tough, weather-resistant polyurea to safeguard your investment. The cabinet front is protected by a rigid metal grill, backed by acoustically transparent foam.
