Overview

Yamaha DBR15 is a bi-amped 15-inch powered PA designed for output and portability. Manufacturer specs state 132 dB peak SPL, 50 Hz–20 kHz (-10 dB) bandwidth, FIR-X 2.1 kHz crossover, and 90°×60° coverage, with D-CONTOUR/HPF and a basic 2-in mixer for FOH or monitor use [1][2][3].

Scientific Validity

\[\Large \text{0.6}\]

Independent full-range lab FR/THD data are scarce; therefore we lean on clearly documented manufacturer specifications (SPL, bandwidth, crossover, coverage) and a reputable review noting clean behavior at high levels. Provisional until third-party data appear; specs are internally consistent across Yamaha materials [1][3][4].

Technology Level

\[\Large \text{0.6}\]

Solid, industry-standard implementation: Class-D bi-amp with FIR-X linear-phase filtering and sensible protection/limiters; no networked control or app. Competent rather than cutting-edge [1][2].

Cost-Performance

\[\Large \text{1.0}\]

Target price: 549 USD [5]. We searched for equal-or-better 15-inch powered tops (user-visible functions comparable, ≥132 dB peak SPL). Examples: EV ELX200-15P (132 dB) and Turbosound iQ15 (132 dB) meet the performance bar but are costlier in current market listings [8][9][10]. JBL EON715 adds Bluetooth/app yet is 128 dB, thus not equivalent in output [7]. Since no cheaper equivalent exists, CP is clamped to 1.0 per the rule. Short equivalence note: bi-amped Class-D, comparable DSP, and manufacturer-rated 132 dB peak SPL [7][8][10].

Reliability & Support

\[\Large \text{0.7}\]

North America offers a long 7-year warranty on Yamaha Professional Audio loudspeakers and broad service coverage—strong indicators for long-term support [6].

Rationality of Design Philosophy

\[\Large \text{0.6}\]

Design prioritizes high usable SPL, straightforward deployment (D-CONTOUR/HPF), and portability over expanded feature sets. Choices are coherent for gigging FOH or wedge roles [1][2].

Advice

If you require Bluetooth/app control, consider JBL EON715 (but lower max SPL at 128 dB) [7]. If you want similar SPL with deeper onboard DSP, look at EV ELX200-15P or Turbosound iQ15—both meet 132 dB but typically cost more [8][9][10].
