Introduction
The K&F GRAVIS 8 W is a compact, lightweight, high-performance speaker in a multifunctional housing. The compact full range speaker is particularly suitable for heavy duty use in the demanding pro.RENTAL segment, and is equipped with an 8” low-mid frequency chassis, a 1” high-frequency driver on a rotatable 85° x 55° CD horn and a passive crossover. Depending on the type of application, the 2-way system can be used as a main system for speech and music sonication at smaller to medium-sized events. In larger and more complex applications, it is recommended to use it as a centre or offset system, or as a fill-in or effect speaker. Due to the small footprint and outstandingperformance, the speaker can also be used as a highquality stage monitor.
The design of the K&F GRAVIS 8 W is discreet and functional. The front of the speaker is protected by a grille behind black, opaque filter foam. For an alternative setup, the housing has two alignment angles for monitor operation on stage. All trays are protected from damage by plastic sliders, and the speakON® sockets are recessed. The speaker can be easily carried by the ergonomic handles and, thanks to its low weight and integrated pole mount flange, it is very easy to position on high stands or stand surfaces. The swivel bracket can be fixed quickly and securely to the K&F VariPoint without using tools (in compliance with BGV C1).
The K&F SystemAmps, which are specified for operation, allows a variety of system combinations, such as one with the high-performance subwoofers of the K&F NOMOS range. Or combine a Lab.gruppen IPD 2400 with PASSIO Subwoofers. With its maximum sound pressure level of 130 dB, the K&F GRAVIS 8 W provides high dynamicreserves precisely for live applications. It also has the neutral and natural sound character that is typical for K&F.
