Product Details FP4
FP4 is a miniature point-source loudspeaker for short-throw distributed systems where space and sight lines are limited. Its wide, smooth operating response supports music and speech in spot and fill positions.
Applications range from small stages, theatres and worship spaces to museums, galleries, bars and restaurants. The portable format also suits corporate AV and fills within larger systems. A subwoofer can extend FP4 into a compact premium background-music system.

The passive two-way assembly combines a 4-inch LF driver with a 1.25-inch voice coil and a 0.7-inch-exit HF driver using a 1-inch high-temperature polymer dome. Coaxial Point Source geometry provides 110° conical coverage, with a specified maximum of 108 dB peak.
A textured birch plywood enclosure contains threaded fittings for compatible U-bracket, wall-bracket and microphone-stand mounting. The steel grille has a triple-layer polyester backing for a discreet professional appearance.
iKON provides integrated amplification and processing. VIA amplifiers can also be used with DX4.0, DX0.4 or DX0.6 controllers. DISPLAY 3 predicts the system in a three-dimensional venue model.
