The Optimal Audio 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 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 grill and finished in neutral white.
Each Up 4S can be run on a variety of 100 or 70 volt taps, or at low impedance. Tap selection is via a rotary switch behind the removable grill.
SmartAmps or Zone will provide optimal performance and loudspeaker protection. When coupled with the Zone series, a ZonePad and the WebApp makes setting up a system and end user control simple and intuitive.
