Overview

The Yamaha DXR15MKII is a 15-inch, bi-amped powered loudspeaker aimed at portable PA and stage-monitor duties. It delivers 134 dB peak SPL (1 m, on-axis), covers 49 Hz–20 kHz (-10 dB), and uses a 48-bit DSP platform with Yamaha’s FIR-X linear-phase crossover and D-Contour multiband dynamics. The enclosure provides 90°×60° coverage, integrated pole mount (0°/7°), and weighs 21.8 kg. All figures above are manufacturer specifications. [1]

Scientific Validity

\[\Large \text{0.5}\]

Independent, lab-grade measurements for THD/IMD, on-axis FR deviation, directivity index, and long-term power compression were not found at the time of review. As such, we rely on manufacturer data: 134 dB peak SPL, 49 Hz–20 kHz range (-10 dB), 1100 W dynamic power split 950 W LF / 150 W HF, and 90°×60° nominal directivity. These suggest competent performance for its class, but without third-party verification we keep the score at the policy default and will revise if credible measurements emerge. [1]

Technology Level

\[\Large \text{0.9}\]

DXR15MKII implements linear-phase FIR-X crossovering (time-alignment and phase management), 48-bit DSP, and D-Contour program-dependent dynamics to preserve tonal balance with output level changes. The bi-amped Class-D module (1100 W dynamic) and enclosure/mounting options reflect mature but still modern PA engineering. [1]

Cost-Performance

\[\Large \text{0.9}\]

Cheapest equal-or-better alternative found: JBL PRX815W—a 15” powered PA with 137 dB max SPL and Wi-Fi app control (PRX800W series). Street price observed at 899.99 USD new. [3][4]
Review target price: 995.99 USD. [2]

Calculation: 899.99 USD ÷ 995.99 USD = 0.9036 → 0.9 (rounded to one decimal per policy).

Equivalence note: PRX815W matches core functionality (powered 15”, onboard DSP, pro I/O) and is equal-or-better on claimed max SPL (137 dB ≥ 134 dB). [1][3]

Reliability & Support

\[\Large \text{0.8}\]

Yamaha maintains extensive global pro-audio service networks. The DXR enclosure (molded ABS), integrated mounting, and conservative protection/DSP design align with portable/touring use. Warranty terms vary by region; typical coverage is around two years for powered speakers (confirm locally). Given Yamaha’s track record and parts availability, long-term support prospects are good. [1]

Rationality of Design Philosophy

\[\Large \text{0.9}\]

The engineering prioritizes measurable outcomes—phase-coherent crossover behavior (FIR-X), program-adaptive dynamics (D-Contour), and controlled directivity (90°×60°). These choices are technically sound for maximizing intelligibility and maintaining tonal balance at high output without resorting to subjective voicing. [1]

Advice

DXR15MKII suits users who need high output, reliable protection/DSP, and straightforward analog I/O with minimal setup. If you value wireless/system-level app control and the highest claimed SPL per dollar, shortlist JBL PRX815W as a strong price/performance foil. If you prefer Yamaha’s ecosystem and consistent voicing with DXS subs, the DXR15MKII remains a safe, field-proven pick. [1][3][4]
