The Martin Audio FP4 is a compact passive two-way coaxial loudspeaker designed for discreet, high‑clarity sound reinforcement. Featuring a 4-inch low-frequency driver and a 1-inch dome/0.7-inch exit compression driver, it delivers a smooth, phase-coherent response with a wide 110° conical dispersion for even coverage. With an on-axis frequency response of 142 Hz–18 kHz (±3 dB), 60 W AES power handling (240 W peak), and a maximum SPL of 108 dB peak at 1 metre, the FP4 excels in front-fill, delay, under-balcony, corporate, and immersive applications where size and fidelity matter. Connectivity is via two NL4MP speakON-type connectors and a Phoenix terminal block, while an internal 2.6 kHz passive crossover ensures seamless driver integration. The robust plywood enclosure, hard-wearing textured paint finish, and perforated steel grille with triple-layer polyester backing offer touring-grade durability. Threaded inserts support U-bracket, wall bracket, and microphone stand mounting options. Dimensions are 130 x 130 x 126 mm, and weight is just 1.9 kg.
Supplied as a set of four FP4 loudspeakers in a protective case, this package is ideal for rental, corporate AV, theatres, and installations requiring compact, consistent coverage.
