Compact power, professional clarity. The Fostex PM0.4cB is a high-efficiency active/passive speaker system designed for small studios, multimedia production, and creative workspaces. With its rich and clear sound, it’s ideal for post-production, broadcast, and music recording, delivering professional results in a compact format.

Each speaker features a 2-way design: a robust 4" glass-fiber woofer with a rolled rubber surround for tight low-end response and a 0.75" silk-dome tweeter that delivers clear, natural highs. The rear bass reflex port and wooden cabinet design further enhance warmth and depth, offering a surprisingly full sound for such a compact system.

The right speaker houses the 30W amplifier, powering both the active and passive units. With RCA and 1/4” TS inputs, it's easy to integrate into your setup. The package includes everything you need to get started: power cable, bare-wire speaker cable, and a dual RCA to dual 1/4" audio cable.
