Optimal Audio UP4S-W

Two-way passive, full-range, low profile 4” ceiling speaker

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

Up 4S 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.

The Pendant 1 and Grille 1 accessories offer further flexibility in installation and applications, allowing you to either elegantly suspend Up 4S speakers as stylish pendants or achieve a sleek, bezel-less grille appearance. These accessories are available in both black and white, helping to blend into any architectural environment.

The wide 150° conical coverage of Up 4S makes it particularly suitable for low ceilings and reduces the number of speakers required for even coverage leading to a reduction in installation cost. A shallow steel back can allows installation in ceilings with minimal cavity depth. An integral fixing system is included to achieve a simple and clean installation. Up 4S has a steel back, perforated steel grille and finished in neutral white.

Each Up 4S 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 and loudspeaker protection via onboard presets. When coupled with a Zone and WebApp , system set up and end user control is straightforward, and can be further supplemented by ZonePad wall controllers.
