In 1975, Peavey revolutionized the working man's loudspeaker with the SP®1. Now, Peavey does it again with the Dark Matter series of enclosures. Thanks to its new advanced DSP-equipped power section, the high-S.P.L. (Sound Pressure Level) Dark Matter series outperforms any existing enclosure in its category. The Dark Matter LCD display and associated selector knob allow users to choose various parameters of operation for the DSP-based EQ. This includes bass and treble control access, as well as EQ presets for different applications or speaker positions/locations. These presets provide users with a highly flexible method of configuring the powered speaker system for a specific use with minimal time and effort. Fan cooled for maximum reliability, the DM 115 features Peavey's exclusive Quadratic Throat Waveguide™ technology that helps deliver pristine, precise sound. The ultra-reliable Dark Matter series enclosures are built tough with steel grilles and rugged injection molded cabinets. Their convenient design allows for use as floor monitors or pole-mounted speakers. Perfect for band, DJ or other musical applications, the Dark Matter enclosures produce crystal clear professional audio.
