Yamaha makes it sound good
Yamaha has been building musical instruments for well over a hundred years, so they know a thing or two about acoustics. They used that knowledge and skill to design and build the DXR15 active loudspeaker. Each DXR15 speaker is a self-contained PA system, including high- and low-frequency drivers, amplifiers, digital signal processing, dynamic limiting, and a 3-channel mixer all mounted in a rugged, non-resonant, and lightweight ABS enclosure.
Loud and versatile
Each sturdy DXR15 cabinet houses a 15" woofer, a 1.4" compression driver, and 1,100 watts of amplification. This compact and efficient speaker from Yamaha can produce astounding sound pressure levels — up to 133 dB. You can put a single DXR15 in a classroom, restaurant, or small auditorium, for instance, plug in a microphone, and talk through a compact and very portable public address system so everyone can hear you clearly throughout the room. You can even play music directly from an instrument and your portable music player through this speaker. As part of a larger PA, a pair of DXR15s can deliver your performance with incredible power and clarity, at levels that everyone can feel as well as hear.
You can use your DXR15 on stage as a floor monitor or on a stand as a main PA speaker, and mounting options are available for permanent installations. The "D-CONTOUR" selector enhances the bass and treble for permanently mounted or pole-mounted speakers, or reduces bass for stage monitors, where the floor would normally boost it. High-pass filters let you trim the low bass out of the DXR15 to maximize its performance when matched up with a Yamaha DXS12 or DXS15 subwoofer.
Yamaha engineered the two drivers, the two built-in amplifiers, and the enclosure to all work perfectly together, while extensive protection circuitry ensures the speaker long-term reliability. Microprocessors separately monitor the power supply, the amps, and the two drivers for any overheating or overloading conditions and either limit the amps' outputs or shut them down for the safety of the whole speaker.
