It features an 8-inch low-frequency transducer along with a 1.75-inch high-frequency diaphragm compression driver, both powered by a robust Class D amplifier that outputs a total of 1000 watts. This loudspeaker is engineered to provide a wide frequency response range from 61 Hz to 20 kHz, ensuring clear and accurate sound reproduction for both music and speech.

The K8 incorporates advanced DSP technology, which includes DMT™ (Directivity Matched Transition) for smooth coverage across the listening area. It also offers intrinsic correction tuning and DEEP™ (Dynamic Extension and Excursion Processing) for enhanced low-frequency performance, optimizing the acoustical output regardless of the environment. The loudspeaker's enclosure is constructed from rugged ABS material for durability and features a professional appearance suitable for any setting.

Connectivity is versatile with dual balanced XLR and 1/4" TRS inputs, alongside RCA inputs for added flexibility in connecting various audio sources. The K8 also provides mic/line level input options, with independent gain controls and a selectable high-pass filter to accommodate different audio configurations. The loudspeaker can be pole-mounted, wall-mounted, or used as a floor monitor, allowing for adaptable placement in diverse venues.
