The speaker systems of the XKB series are high-performance active speaker systems in light-weight and rugged plastic cabinets. They can be flexibly used for permanent installations and professional live applications. The 2-way speaker systems are designed as full-range bass-reflex systems with separate power amplifiers for the high-frequency range and the low-frequency range featuring inputs for microphones and line sources and parallel outputs for coupling with other active speakers. The DSP (digital signal processor) features convenient application presets for quick sound contouring (models XKB-212A and XKB-215). The built-in Bluetooth player allows for streaming music wirelessly from smartphones or tablets via Bluetooth. The speakers systems are protected through limiters and extensive protective circuits. The enclosure offers multiple setup options (use as a floor monitor, wall or stand mounting).
