WORK IC 4 PRO ลำโพงติดเพดานขนาด 4 นิ้ว 4” dual cone woofer + ¾” tweeter.

The IC Pro series of WORK Pro is composed of three ceiling speakers with separate woofer and tweeter. They provide high sound quality in your installation.

They are made of high impact resistance ABS plastic and feature a metal grille as well as a metal back enclosure which contains the crossover network and transformer. A bass reflex design, coupled with extended enclosure volume and bass resonance tube provide better bass extension.

They are suitable for high impedance (70 V, 100 V) voltage line and low impedance (8 ohm) installations. The power tap selector is accessible from the front of the speaker so levels can be adjusted after installation. They also have a detachable Euroblock connector, contained within a metal compartment for ease of installation.
