Speaker System SB-R1
Achieves a
superlative level of sound reproduction,
building on our
linear-phase, point-sound-source concept.

Point-Sound-Source Speaker System
For soundstage focus
and precise imaging, the wave-fronts from a speaker’s drive units should
ideally be aligned, arriving simultaneously at the listener’s ears regardless
of the listening position. In other words, the speaker system should appear to
have have only one point sound source.
The newly developed
flat coaxial two-way speaker unit, combining midrange and treble drivers, works
with a virtual coaxial woofer to realize a point sound source, providing smooth
directional characteristics over the entire frequency range, without peaks or
dips.

Phase Precision Driver (Flat Coaxial 2-Way Speaker
Unit)
For faithful
reproduction of mid-range and high-frequency sound, Technics has developed an
all-new flat coaxial two-way drive. The flat mid-range diaphragm is of a
sandwich construction, using lightweight, high-rigidity carbon cloth skins and
aluminium honeycomb core.
It maintains a
perfect pistonic motion over a frequency band extending beyond the crossover
point with the tweeter, while eliminating the frequency distortions caused by
the ‘cavity effect’ in conventional cone diaphragms. The magnetic circuit
employs a large magnet, copper cap, copper shorting ring and short voice coil
with high-density edgewise winding to achieve high drive power and low distortion,
while the speaker chassis is die-cast aluminium, with a resonance-dispersing
structure to eliminate even the smallest unwanted vibration.

Ultra Wide Range Reproduction
Thanks to a carbon
graphite dome tweeter mounted at the center of the flat mid-range drive unit,
the SB-R1 is capable of reproducing frequencies all the way up to 100 kHz. And
with bass extension down to 20 Hz, it’s ready to deliver the vast frequency
spectrum offered by high-quality, high-resolution music sources.

High Rigidity Entasis Form Cabinet
A 50-mm-thick baffle
used in the cabinet supports the speaker units rigidly and suppresses
undesirable resonances, while side panels comprising eight layers of MDF give
the cabinet a curved form, suppressing unwanted vibration and reducing internal
and external diffraction and reflection.
An internal
partition divides the cabinet into upper and lower sections, and eliminates
low-order standing waves in the vertical direction. The choice of absorbent
acoustic material and its position were optimized based on the frequency band
of each drive-unit as well as the cabinet volume, thus further suppressing
standing waves inside the cabinet, and even the rings round each drive unit are
made of a material with high internal loss to eliminate unwanted emitting from
anywhere other than the speaker sound diaphragm.
The glossy finish on
the cabinet is created through a series of processes including repeated
coating, sanding, and polishing, the high degree of craftsmanship complementing
the speakers’ high-quality sound. The finish even suppresses fine vibrations
generated on the cabinet surface, thus contributing to the accuracy of the
sound.

Speaker System

Low Distortion 16-cm Long Stroke Woofer
Technics has
developed a long-throw woofer capable of reproducing super-low frequencies with
dramatically reduced distortion, giving powerful, dynamic and responsive bass.
A push-pull edge (Symmetrical Surround Technology, SST) design cancels
secondary harmonic distortion in the low-frequency range.

High-quality Network Circuit
The High-quality
Network Circuit was created as a result of extensive designing and listening,
in order to maximize the performance of each speaker unit and achieve a
balanced sound. To prevent interference between the drive units and minimize
the effect of vibration, separate network boards for woofer, mid-range and
tweeter are optimally arranged inside the cabinet.
