The DXR15mkII achieves a class-leading maximum SPL of 134dB and full bandwidth performance by combining a powerful Class-D amplifier with a high-power woofer and Yamaha's cutting-edge technologies.Louder, Lighter, LegendarySince its inception, the DXR Series has long signified the confluence of raw power and technology; the DXR Series has long predicted a convergence of raw power and technological innovation that reliably harnesses and delivers impressively high output with superior quality and clarity. The DXR mkII Series powered loudspeakers are the upgraded models of the series that add even more SPL and feature a more significant, lighter 1.75-inch Neodymium HF compression driver for apparent voice reproduction and musicality. The DXR mkII Series comprises four full-range models perfectly suited for front-of-house sound, monitors, simple amplification, rigged applications, and more. Combining the series with the DXS subwoofers will elevate the system's performance, giving the versatile control of its thunderous bottom end.Yamaha Ingenuity and NEXO Expertise Combine for a Lineup of DXRsAdded crucial insight and expertise that led to design improvements based on the ever-evolving demands of sound reinforcement professionals. Whether for fixed applications or mobile live performances and in whatever direction one wants to take the sound.Less Weight, More PowerAll DXR mkII Series transducers were meticulously selected and thoroughly customized to deliver ultimate performance. The high-power output woofers deliver very low distortion and define deep bass. At the same time, the equipped, more significant yet much lighter 1.75-inch Neodymium precision HF compression drivers produce accurate midrange and high frequencies up to 20 kHz with less weight.Ultra-Precise 48Bit DSP Processing for High-Definition SoundAll full-range models feature Yamaha's proprietary FIR-X tuning utilizing linear phase FIR filters for the crossover network. FIR-X tuning 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.Intelligent Dynamic Control for Consistent Clarity at Any Output Level With the DXR mkII Series, D-CONTOUR provides a more detailed sound tuning with two different settings: FOH/ MAIN mode or MONITOR mode. FOH/MAIN mode boosts low frequency to compensate for low-end, typically missing when speakers are used in suspended applications or mounted on a speaker stand.Extensive DSP Protection Functions for Maximum OutputDuring the development of the DXR mkII series, the durability of each transducer and the overall amp output were measured and tested through countless indoor and outdoor listening tests.Compact, High-Power DXR mkII Amp ModulesAll DXR mkII Series loudspeakers are equipped with highly efficient Class-D amplifiers optimally designed to match the DXRmkII's HF and LF transducers. These high-performance amplifiers deliver the highest sound output in their class with 1100W of power, producing an impressive SPL of up to 134dB. They also provide swift attack and superior transient response, significantly contributing to these speakers' incredible audio performance.Intelligent Onboard 3-Channel MixerThe DXR mkII Series features a flexible onboard mixer with various inputs, making it ideal for simple vocal/ instrument amplification. With its flexible IN/OUT, the DXR mkII Series can comprise a complete sound reinforcement system or seamlessly integrate into a setup utilizing DZR or DXS Series speakers. The DXR mkII onboard mixer can handle up to three simultaneous inputs.
