Ceiling speaker

The IC PRO 4 is one of the models that composes the IC Pro Series of WORK Pro. This serie is composed of three ceiling speakers with separate woofer and tweeter. They provide high sound quality in your installation.

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.
