The CLa21 is a high-power, bi-amp 2-way, line array module engineered to deliver an incredible output for use in both indoor or outdoor. The Tecnare CLa21 has enough new solutions to make the work of sound engineers easier .

First of all we have established a design criterion in which the size of the cabinet is extremely compact. The bass and mid section are conformed by two 10″ dipolar mounted drivers and High frequency is handled by a 1.4” exit (3-inch voice coil) compression driver attached to a pattern controlled (75º horizontal x 13º vertical) symmetrical curved waveguide. The advanced bass-reflex and port arrangement delivers full bandwidth capabilities with an extended LF output. Due to the dipolar arrangement of the LF drivers, a broadband, horizontal dispersion control nominally is maintained down to approximately 500 Hz.

The system’s shape is trapezoidal , so we can better angle and focus its elements. This feature could partially solve front applications, if the front focused elements could be managed independently apart from the other elements of the array.

The enclosure has been made with the latest techniques assuring a perfect and rigid construction. Weather protected finish is provided, as the cabinet is covered with Poliurea protection finish and protected with epoxy powder coating grills.
