Product Information
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 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.
Features
- 4” coaxial driver
- Discreet size with shallow back can
- Unobtrusive design
- 8 ohm or 70/100V line operation
- Range of power taps
- Wide conical coverage pattern
- Integrated mounting hardware
