The DHR15 is a 2-way bi-amp powered loudspeaker equipped with a 15-inch woofer and a 1.4-inch HF driver, perfect for use as a main speaker. Combining a 1000W amplifier and high-performance DSP with the same plywood construction found on Yamaha’s high-end DZR Series, the DHR15 offers best-in-class sound quality and durability.
The DHR Series offers an ideal solution for anyone ready to step up their sound reinforcement game to a new level of professional quality, accuracy, and performance. Premium plywood cabinets finished in a tough polyurea coating provide durability not found on other loudspeakers in this class.
Each model in the series has been optimized to meet the demands of a variety of sound reinforcement applications, with a 10” model for fixed installation and utilities, a 12” model designed for use as a floor monitor, and a 15” version for FOH applications—all featuring custom transducers driven by DSP-equipped class-D power amplifiers to deliver stunning sound quality and clarity. Combined with practical features adapted for their specific applications, the series gives you the flexibility to choose the ideal speaker for a wide variety of sonic environments. Isn’t it time you audition DHR quality and performance to improve your sound?
The DHR Series features a comprehensive lineup optimized to meet the demands of specific applications. The 10” model is equipped with a rotatable HF horn and a dedicated UB-DXRDHR10 U-bracket for use in fixed installations and utility, while the 12” model is the first Yamaha speaker to feature a coaxial compression driver for improved clarity and smoother frequency response for floor monitoring. The series is rounded out by a 15” model featuring dual-angle pole sockets and rigging points for use in fixed installations or as temporary main speakers for sound reinforcement.
The high power output woofers deliver well-defined, powerful bass with minimal distortion, while the 1.4” precision compression driver* produces accurate mid-range and high frequencies.
The DHR series feature plywood enclosures like our acclaimed DZR loudspeakers to deliver outstanding durability and acoustic performance.
All full range models feature Yamaha's proprietary FIR-X tuning™ utilizing linear phase FIR* filters for the crossover network. FIR-X tuning™ simultaneously optimizes frequency and phase response while adjusting the time alignment between the HF and LF transducers. This creates a very smooth response around the crossover point, providing much better clarity and imaging than what is possible with typical crossovers.
All signals are precisely processed by a high-performance processor for high definition sound quality. All full-range models employ high-precision 24bit discrete A/D and D/A converters with superior S/N ratio and dynamic range.

D-CONTOUR is an intelligent multi-band compressor that gives you powerful and consistent sound throughout all output levels. By constantly monitoring the output of multiple frequency bands and calculating the optimum EQ adjustments for each, even the maximum sound output maintains outstanding clarity and musicality. With the DHR Series, D-CONTOUR provides a more detailed tuning of your sound with two different settings: FOH/ MAIN mode or MONITOR mode. FOH/MAIN mode boosts low-frequency to compensate for low-end that is typically missing when speakers are used in suspended applications or mounted on a speaker stand. MONITOR mode is completely optimized for monitor application by intelligently taming down the low-frequency, smoothing out a wide range of frequency bands to give you stunning clarity for monitoring your sound. Both of these presets were perfected by performing countless listening tests with skilled sound engineers, giving you a multi-band compressor that performs dynamically, delivering consistent sound with low distortion at any output level.
In a typical system comprising passive loudspeakers, power amps and signal processors, trying to set optimal parameters for each component can be a daunting task. One of the advantages of active loudspeakers is that the combination of transducers and amps can be perfectly optimized. During the development of the DZR, DXR mkII, DHR, DBR and DXS series, we measured and tested the durability of each transducer and the overall amp output through countless indoor and outdoor listening tests. Based on the test results, we were able to set the optimal limiter point for each model using precise DSP control.
In addition to the optimal limiting, our speakers employ many of the same protection functions used in our top-class PC-D Series professional power amplifiers. A microprocessor and high-power DSP monitor the status of the power supply, power amplifiers, transducers and ongoing signals to protect all aspects of each component. As a result, these speakers can perform to their full potential while ensuring reliable operation in even the most severe conditions.
The DHR’s lightweight, high performance Class-D amplifier is capable of producing up to 1000W* of power, achieving an SPL of 131 dB (DHR15), delivered with remarkable clarity and dynamic characteristics.
DHR Series speakers have two input channels. CH1 has a combo jack which accepts both XLR and TRS Phone allowing for either Mic or Line level input signals. CH2 offers two input options; a combo jack that accepts XLR or TRS Phone, and a pair of RCA pin Jacks for input from CD players or other stereo line-level sources.
The onboard mixer allows you to select either CH1+2 MIX to mix the signal of CH1 and CH2, or CH1 THRU to pass the signal from CH1 only.
Depending on the venue, sometimes your mix can fall prey to low ceilings or other room attributes that can impede a clear, even mix and detract from the audiences' listening experience significantly. The DHR15's pole mount socket offers two positions - 0° or -7° - to direct the acoustic energy away from reflective surfaces and on to your audience where it belongs.
