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.
