Optimal Audio UP 4 Two Way Passive Full Range 4 Inch Subwoofer Ceiling Speaker

Up 4 is a discreet, two-way 4” ceiling speaker delivering consistent coverage and full frequency sound to a wide range of cost conscious, commercial environments from hotels and concourses to retail outlets, bars and restaurants.

An integral fixing system is included to achieve a simple and clean installation.  Up 4 has a steel backcan and perforated steel grille and is finished in neutral white.

Up 4 features a 4” (105mm) low frequency driver paired with a 0.7” (20mm) silk dome tweeter. It is suitable for both high quality speech and music reproduction. A conical 120° coverage pattern delivers consistent sound where it needs to go.

Each Up 4 can be run on a series of 70 or 100 Volt taps or at low impedance. Tap selection is via a rotary switch behind the removable grille.

A SmartAmp or powered Zone will provide amplification, optimal sound performance and loudspeaker protection via presets. When coupled with a Zone and WebApp, system set up and end user control is easy, and can be further supplemented by ZonePad wall controllers.
