Martin Audio FP15

The FP15 is a two-way passive loudspeaker featuring a high-specification 15” LF driver and a 1.4” exit HF driver with a 3” diameter titanium diaphragm. It effortlessly delivers an impressive maximum SPL of 132dB peak and has a well-defined dispersion pattern of 80° horizontal x 50° vertical, with constant horizontal directivity characteristics.

Its exemplary coverage pattern is achieved by incorporating a dedicated waveguide within the magnet structure which merges into a specially contoured LF cone. With the waveguide and cone combining to form the HF horn, this innovative arrangement avoids a separate ‘add-on’ horn which would impede the wavefront from the cone and cause irregularities in the frequency response. It also improves on conventional through-the-pole coaxial designs, which can suffer from high frequency beaming.

The FP15’s durable birch plywood enclosure is finished in hardwearing textured paint and incorporates multiple threaded inserts to cater for a wide range of mounting options and accessories — including eyebolt, yoke, wall bracket and truss mounting. A dual pole-mount socket with 0° and 15° down-tilt angles is incorporated into the base of the enclosure, and twin handles aid installation and deployment. A steel grille with a triple-layer polyester backing presents a discreet, professional appearance, while resisting dust and water ingress to IP54 environmental rating.

The FP15 can be used in either portrait or landscape orientation by rotating the driver within the enclosure. To make this operation quick and easy, the grille is secured by proprietary quick-release latches, and the driver fixed to the baffle by means of captive release clamps. Loosening these by hand allows the driver to be quickly rotated through 90° and re-tightened. FP15 can be powered by iKON amplifiers, or by VIA amplifiers when used with a DX4.0 controller, or alternatively a DX0.4 or DX0.6 controller. FP15 systems can be modelled in 3D using Display 3 design and prediction software.
