Yamaha loudspeakers don’t owe their superb audio performance to cutting-edge DSP technology alone.
Only in combination with the very best amplifier units and Yamaha’s accrued knowledge of acoustic
technologies can these speakers operate at such a consistent, reliable level of performance.
Amplifier and Speaker Technologies
DSR, DXR, DBR and DXS Series are all equipped with highly efficient Class-D amplifiers
that were designed to match HF and LF transducers and get the very best performance out
of each model. Combined with customized speaker units, these high-performance amplifiers
deliver the highest sound output in their class, producing up to 138dB SPL in the high-end
DSR215. They also provide very fast attack and superior transient response, contributing to
audio performance substantially.
Rugged Enclosure Design for Optimal Acoustic Performance
Wide Dispersion Constant Directivity Horn for Consistent Sound Dispersal
Choosing the right transducer can have a considerable
impact on the overall sound of a speaker and it’s not a
task our team took lightly. All DSR, DXR, DBR and DXS
transducers were meticulously selected and thoroughly
customized in order to deliver the best possible
performance. The detailed characteristics and behavior
of each transducer were fully analyzed and evaluated
with sophisticated computer simulations in order to help
realize their full performance potential. The high power
output woofers deliver minimal distortion and defined,
deep bass, while the precision compression drivers
produce accurate midrange and high frequencies up to
20kHz.
The extremely accurate constant
directivity horn was designed with the
goal of minimizing the radiation pattern
deterioration in oblique directions that
other, more conventional horns are
prone to. This can help to achieve a more
ideal coverage area without irregularities.
With Yamaha’s wide dispersion constant
directivity horn, sound expands in a more
rectangular pattern, evenly dispersing
wide-frequency sound to the outer-most
edges of the coverage area.
The durability, materials, and shape of the enclosure have a profound effect on the overall sound of
the speaker. Even if high-quality amplifiers and transducers are used, a lack of durability, or errant
design of the enclosure will create unwanted resonance and noise. By drawing from Yamaha’s
extensive history of developing loudspeakers and studio monitors, we carefully simulated and
designed highly durable cabinets that eliminate unwanted resonance, and help deliver
high-definition sound regardless of the output levels.
