Biamp Desono MASK4CT-W / 911.0640.900 Two-Way 4.25 Inch Surface Mount Loudspeaker Pair in White featuring Innovative ClickMount™ bracket, and Loudspeaker Overload Protection for 24/7 Failsafe Operation

The Biamp Desono MASK4CT / 911.0640.900, 4.25" surface mount Loudspeaker Pair delivers crystal clear sound for all your public address and background music needs. Provided in white but also available in black, its 4.25” coated paper cone woofer and a 1” silk dome tweeter results in a high SPL and extremely low distortion, ensuring unprecedented clarity over the entire frequency spectrum.

The MASK4CT utilizes a 5-position switchable transformer ranging from 1.25W to 20W with low-impedance bypass for constant-voltage operation, making it an excellent choice for large areas of BGM.

Designed with the installer in mind, the MASK4CT ships with the patented ClickMount bracket, enabling all audio connections to be made at the bracket itself. Pre-defined horizontal and vertical notches in the bracket make Loudspeaker adjustments fast and repeatable. To complete the installation, simply ‘click’ the Loudspeaker in place.

The Desono MASK4CT is designed for outdoor applications such as patios or concourses, and an ideal choice for both indoor and outdoor distributed audio applications that demand superior speech intelligibility and full range music reproduction.
