Biamp MASK4CT Black

The Desono MASK4CT two-way, 4.25″ surface mount loudspeaker delivers crystal clear sound for all your public address and background music needs. Available in black or white, 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.
