Technics SB-C700-K Bookshelf Speakers (Black)

Description

Speaker System SB-C700
Realizes high transparency and a precise sound image,

building on our linear-phase, point-sound-source concept.

Point-Sound-Source Speaker System
Technics’ newly developed flat coaxial two-way speaker unit
combines a tweeter for high frequencies and a woofer for mid-range and bass.
Because the tweeter is at the center of the woofer, the speaker acts as a point
sound source, providing a coherent, integrated sound across the frequency
range, without directional anomalies. As a result, the Technics Speaker System
deliver a live superb soundstage focus, excellent imaging and the ambience
required to deliver the ‘live music’ experience.

Phase Precision Driver (Flat Coaxial 2-Way Speaker Unit)
The flat coaxial two-way speaker drive unit is an original
Technics development, designed for the faithful reproduction of mid-range and
high-frequency sound. The flat woofer diaphragm has a sandwich-structure using
lightweight, high-rigidity carbon fibre skins and a honeycomb core, and is
designed for a highly accurate pistonic motion over a frequency range extending
beyond the crossover frequency with the tweeter, thus ensuring smooth
integration. 

The flat design eliminates the frequency anomalies due to the cavity effect
caused by conventional cone diaphragms, while the magnetic circuit employs a
large magnet, copper cap and shorting ring, and a short voice coil with
concentrated edgewise winding for high power with low distortion. The drive
unit chassis is in highly rigid die-cast aluminium, with the chassis ‘legs’
having a resonance dispersing structure to eliminate even the smallest unwanted
vibration, to help the drive unit deliver accurate and powerful bass.

High Rigidity Entasis Form Cabinet
The SB-C700 cabinet is designed to support the Point Source
drive units securely, preventing unwanted resonance and ensuring a smooth flow
of sound without diffraction or reflection. The front baffle is designed for
maximum stiffness and resonance-damping, while the side panels are convex
high-rigidity boards with a maximum 42-mm thickness, designed to damp down
resonance while also preventing internal reflections.

The monocoque cabinet offers high rigidity, as each side of the cubic structure
reinforces the adjacent panels. This reduces unwanted resonance by controlling
the movement of the individual panels, as well as that of the structure as a
whole, while internal acoustic absorbent material was selected, and its
position optimized, to suit both a drive unit and the cabinet volume, thus
suppressing undesired standing waves.

The bass reflex port on the rear panel is of a ‘parabola’ design, its curvature
continuously varying from the inlet to the outlet to suppress turbulence at the
exit as well flow-noise within the port, thus delivering smooth and powerful
bass sound with minimum noise.

The glossy cabinet is created by repeated coating, sanding, polishing and
finishing with a high degree of craftsmanship. This creates a cabinit not just
attractive to look at, but also able to suppress fine vibrations generated at
the enclosure surface, thus contributing to the accuracy of its sound.

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 and tweeter are optimally arranged inside the cabinet.

Ultra Wide Range Reproduction
The Technics Speaker System is capable of reproducing sound
over the ultra-wide frequency range of up to 100 kHz to deliver the vast
frequency spectrum offered by high-quality, high-resolution music sources. The
result is a faithful reproduction of audio signals with all nuances intact.
