Ultra-Compact. Exceptional Clarity.
FP4
The Martin Audio FP4 is a premium, ultra-compact point-source loudspeaker designed for applications that demand high-fidelity sound from a discreet enclosure. Featuring a 4-inch coaxial driver, it delivers consistent coverage and sonic precision, making it the ultimate choice for architectural spaces and high-end installations.
Precision Coaxial Engineering
Engineered for Excellence.
Coaxial Point Source
The 4-inch LF driver and 1-inch HF driver are aligned coaxially to provide a perfectly phase-coherent output, ensuring natural sound and uniform 110° conical coverage.
Discreet Integration
With its miniature birch plywood enclosure and flexible mounting options, the FP4 blends seamlessly into any environment without compromising on performance.
High Impedance Efficiency
A 16-ohm nominal impedance allows multiple units to be driven in parallel from a single amplifier channel, reducing installation costs and complexity.
Versatile Mounting
Equipped with threaded inserts for brackets and accessories, the FP4 can be deployed as a front-fill, under-balcony speaker, or as part of a distributed system.
