The DSR215 Active Loudspeaker features an ideal combination of advanced digital sound processing and the latest acoustic technologies for Integral Digital Tuning, plus Yamaha’s D-CONTOUR (Dynamic-CONTOUR) multiband dynamic processing for Intelligent Dynamic Control. The DSR215 is loaded with 2 Class-D amplifiers with a PFC (Power Factor Correction) switching mode power supply. One amplifier delivers 850 watts to a premium grade 12" neodymium woofer with 3" voice coil, and a second amplifier supplies 450 watts to a large 2" high-purity titanium diaphragm, neodymium, high-frequency compression driver. A LTBD (Long Throw, Broad Dispersion) Constant Directivity Waveguide Horn spreads the sound across 90° x 60°. The DSR215 has an impressive maximum SPL of 134dB peak.
