Description

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.
Point-Sound-Source 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.
