Floor Standing Speaker SB-G90M2
Grand Class Speaker
Advanced Phase Precision Driver
A point sound source, like in the G90M2, is one of the ideal approaches to achieve it.
A coaxial configuration was adopted and then it was combined with the originally shaped Linear Phase Plug for aligning phases and the Smooth Flow Diaphragm and smooth edge shape for minimum sound reflection.
The SB-G90M2’s 2-way coaxial speaker unit is newly developed for the reproduction of the mid- to high-frequency range in order to realise the clear and high sound quality to deliver smooth, emotion-rich music, while inheriting the concepts of point sound source and linear phase that Technics pursues relentlessly.
Linear Phase Plug
The tip of the Linear Phase Plug is made from a high modulus and density brass material. It prevents the plug from unnecessary vibration effects due to the mid-range unit, thus delivering clear and low-distortion sound.
Smooth Flow Diaphragm
This configuration achieves a wide sound stage and smooth and rich mid to high-frequency range.
To that end, the balanced driver mounting architecture adopted by the previous SB-G90 model was further optimised through the extensive CAE analysis and the speaker mount baffle was newly developed for the secure mounting of the speaker units. In addition, the rigidity of the entire cabinet was strengthened to take advantage of the balanced driver mounting architecture. The strength and shape of each and every one of the parts composing the coaxial speaker was reviewed in order to remove unwanted vibrations and noise as completely as possible. What’s more, a sound path structure is provided inside the cabinet. This new and unique structure effectively eliminate standing waves that cause a resonance peak.
Balanced Driver Mounting Architecture
Together, they further enhance the crispness of sound and three dimensional presentation of sound field.
Standing Wave Termination Structure
Sound absorbing material is installed at the location in the sound path where the speed of sound becomes fastest. This enables the efficient removal of standing waves, which are the cause of resonance peaks, with a minimum amount of sound absorbing material. (Patented)
This structure allows the use of all information necessary for accurately reproducing music, so the speaker system realises more vivid and natural medium and low-frequency sound.
