FlexPoint FP15

15" Very High-Output Point Source Loudspeaker

Where to Buy or Rent

The FP15 is a premium, point-source loudspeaker designed for short and medium-throw applications which require superb sonic performance, very high output, and low frequency extension from a standalone enclosure.


  • Versatile, premium two-way loudspeaker system
  • Multi-angle enclosure with very high output capability
  • Coaxial Point Source configuration with user-rotatable drive unit
  • 15” (380mm)/3.5” (89mm) voice coil low distortion neodymium LF driver
  • 3” (75mm) titanium diaphragm/1.4” (35mm) exit HF driver
  • 80° H x 50° V dispersion
  • Quick-release steel grille
  • 3D prediction software [DISPLAY 3]
  • Powered by iKON or VIA amplifiers


  • Portable live sound reinforcement
  • Theatre sound
  • Fixed installations
  • DJs and corporate AV events
  • Very high-power stage monitoring

With a multi-angle enclosure and a wide range of mounting options, the FP15 is the perfect high-power solution for rental companies and applications which benefit from its flexibility and speed of deployment. When supplemented by a subwoofer, it is an excellent choice for a top-flight portable live sound reinforcement system for bands and DJs. It can also be used as a powerful stage monitor, or in conjunction with a larger touring or installed sound system.

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. FP15 systems can be modelled in 3D using Display 3 design and prediction software.

Architectural Specs

FlexPoint FP15

The loudspeaker shall be a passive, two-way coaxial system comprising a reflex-loaded 15” low frequency driver and a 3” dome/1.4” exit high frequency compression driver. The HF driver shall be loaded with a static waveguide which merges into the shaped asymmetric cone of the LF driver to define the HF horn geometry.

The dispersion pattern of the loudspeaker shall be 80° horizontal x 50° vertical, with horizontal constant directivity characteristics. The on-axis frequency response shall be 50Hz-20kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 132dB peak at 1 metre. Power handling shall be 500W AES, 2000W peak. Rated impedance shall be 8 ohms.

The loudspeaker shall be operated in conjunction with a dedicated electronic controller or controller amplifier.

The multi-angled loudspeaker enclosure shall be constructed from plywood and be finished with a hardwearing textured paint. It shall incorporate two pocket handles and be fitted with a dual pole-mount socket. Threaded inserts shall accommodate eyebolt, yoke, wall bracket and rigging bar accessory options.

The coaxial driver shall be user-rotatable without tools to enable portrait or landscape deployment of the loudspeaker and shall be protected by a perforated steel grille with a triple-layer polyester backing.

The rear connector panel shall be fitted with two NLT4MP type connectors. Low and high frequency sections shall be integrated by an internal 1.1kHz passive crossover network.

Dimensions (W x H x D) shall be 601mm x 460mm x 420mm (23.7in x 18.1in x 16.5in). Weight shall be 27.4kg (60.4lbs).

The loudspeaker shall be the Martin Audio FlexPoint FP15.

Recommended Electronics

FlexPoint systems support a flexible electronics package.

For the optimum sound performance, Martin Audio iKON amplifiers with onboard DSP are recommended.

However, and primarily for installs, Martin Audio VIA amplifiers in conjunction with a DX4.0 system controller are compatible.

When used with iKON amplifiers or DX4.0 controllers, systems utilise Vu-Net.
