Up 4S is a discreet, two-way, passive 4” 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.
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, optimal sound performance and loudspeaker protection via presets. When coupled with a Zone and WebApp, system set up and end user control is straight forward, and can be further supplemented by ZonePad wall controllers.

The Up 4S is a passive speaker, so it requires a separate amplifier to function. Optimal Audio offers compatible amplifiers like their Smartamp series with appropriate power output to drive the Up 4S speakers effectively. When choosing an amplifier, consider the number of Up 4S speakers you plan to connect and the desired listening volume in your space.
