Speaker System SB-C600

Advanced Phase Precision Driver

To reproduce music with enhanced spatial sound expressivity requires that the wavefronts of sounds radiated from the speaker unit are all aligned regardless of the listening position. The concept of point sound source is one of the ideal approaches to achieve it.
To realise the point sound source reproduction, the coaxial configuration was adopted and then it was combined with the originally shaped Linear Phase Plug for aligning phases and the Smooth Flow Diaphragm formed with a shallow-shape diaphragm and smooth edge shape for minimum sound reflection. The result is a spherical wave with aligned wavefronts of radiated sounds.
The SB-C600’s 2-way coaxial speaker unit realises clear sound image localisation and a smooth, high-quality sound, rich of emotion, while inheriting the concepts of point sound source and linear phase that Technics pursues relentlessly.

Linear Phase Plug

The originally shaped acoustic plug is positioned on the front side of the tweeter diaphragm and provides a high-resolution sound reproduction capability and a wide sound stage.

Smooth Flow Diaphragm

If the sound wave has irregularities on its sound transmitting surface, its wavefront becomes disturbed by the shapes of the irregularities, resulting in the degradation of frequency characteristics. High frequencies that have short wavelengths tend to be more susceptible to the degradation of sound characteristics. The woofer diaphragm in the coaxial speaker unit has a shallow shape and smooth edge to reduce sound reflection. The result is minimal disturbance of the wavefronts of sound waves radiated from the diaphragm to realise excellent frequency response and phase characteristics as well as wide directivity.
This configuration achieves a wide sound stage and smooth and rich mid- to high-frequency range.

Smooth Flow Port

A bass reflex port with an ordinary shape produces a large air current vortex that induces annoying high-frequency noise. Technics employed the airflow control method utilised for airplane wings and designed the cross-sectional shape of the port using flow analysis. The optimally designed port shape does not cause airflow disturbance at the opening and ensures high-quality bass reproduction with minimum noise and superb response.
