A compact, yet powerful speaker with the loudest, cleanest output in its class.
The DSR112 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) multi-band dynamic processing for Intelligent Dynamic Control. The DSR112 is loaded with 2 Class-D amplifiers with a PFC (Power Factor Correction) switching mode power supply. One amplifier deliver 850 watts to a premium grade 12" neodymium woofer with 3" voice coil and a second amplifiers 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 DSR112 has an impressive maximum SPL of 134dB peak.
FIR-X tuning
The digital crossover networks use high-order FIR (Finite Impulse Response) filters providing linear phase response. Yamaha's proprietary FIR-X tuning technology simultaneously optimizes frequency and phase response, whilst adjusting the time alignment between the HF and LF transducers. The end result is substantially higher sound quality than can be achieved with conventional analog crossovers.
High Power DSP and 24-bit Discrete ADCs and DACs
All signals are precisely processed by a 48-bit internal processing, (76-bit accumulator), high-performance processor for optimum sound quality. The DSR Series speakers employ high-precision discrete ADCs and DACs with superior S/N ratio and dynamic range. The analog signal is transmitted on dual channels, converted to digital and summed inside the processor. By using this algorithm, an approximately 3dB improvement in S/N ratio was realized. FIR-X tuning provides for the smoothest possible crossover transitions.
D-CONTOUR (Dynamic-CONTOUR)
The D-CONTOUR multiband dynamic processor constantly monitors the amplifier output levels and adjusts the control system. This in turn varies the amount of boost in each frequency band, providing an ideal balance of dynamic sound with consistent clarity at all volume levels. D-CONTOUR can be turned on or off depending on the acoustic environment and type of sound desired.
1300W (LF 850W, HF450W) High Power, High Sound Quality Class-D Amplifiers
Yamaha's next-generation Class-D amplifiers deliver as much as 1300W of power with precision damping for tight and crisp sound from compact, lightweight modules. Through the ideal combination of amplifiers, transducers and DSP, the DSR Series loudspeakers provide the highest levels of power in their class, while maintaining precise dynamics and sound reproduction. Efficiency is such that convection cooling is all that is necessary, eliminating the need for fans.
Full Resonance Switching Mode Power Supply with PFC (Power Factor Correction)
The DSR Series employs a Yamaha-developed high efficiency switching mode power supply with PFC. The full resonance switching method uses both voltage resonance and current resonance, creating a clean power supply waveform with minimal high frequency noise. PFC harmonizes the phases of the load current and power supply voltage, maximizing power output and ensuring stable operation under severe conditions. This clean, efficient power supply enables the entire speaker system to achieve its full performance potential.
3-Way Fail-Safe Protection
To ensure the highest possible reliability, the DSR Series employs many of the same protection functions used in Yamaha's top-class TXn Series professional power amplifiers. These functions protect all aspects of the power supply, power amplifier modules and transducers so that they can operate to their full potential while ensuring fail-safe operation even under the most severe conditions.
The DSR112 performs as main PA and floor monitor and is stand and pole mountable, with a 35mm pole socket. M10 rigging points allow for suspended installation.
Note: The limited warranty on DSR-Series loudspeakers is extended to five years. In addition, all qualified DSR purchasers, thus far, are also retroactively covered by this extension, from the date of original sale.

Comments about Yamaha DSR112 Active Loudspeaker:
Clear sound, especially for vocals. Plenty of headroom. Great for use on stage as monitors. Versital and compact for small stages requiring close band configurations.
Comments about Yamaha DSR112 Active Loudspeaker:
Replaced k12s. Replaced a Verve. Bought one initially for a solid monitor for my axe-fx. This powered driver has replaced both my fbt verve and qsc k12s. Writing this review to say that I just bought yet another; this will be used for the band. Highs are smooth and authentic; lows roar and do not break up. Head room is great. I REALLY like this speaker better than the qsc's and it's less finicky than the Verve. I bought two. woot. Fantastic product for live rock and roll band. We're live players in the regional festival scene and clubs. Doesn't look too fancy, but drives a magnificent sound for monitor, backline or foh.
Comments about Yamaha DSR112 Active Loudspeaker:
Tried JBL PRX 12" (2 of them) side by side with Yamaha dsr's. Got the dsr. The yamaha is wood, but it a fiber glue composite. PRX is real wood. No matter. Sturdy as the jbl, but sounds smoother and alive than the prx when compared next to each other. Blind test (not really/just back turned) and Yamaha jumped out. Power, real pleasing upper mids, and no plastic sound like the QSC K12 (nice speaker) but I do like the sound of the DSR112 more.
