Technics SB-4000
Linear Phase Speaker System
The amazing waveform fidelity of the Technics Linear Phase speaker systems has now gained widespread attention. With the SB-4000 is a similar system . Yet it still retains the essential crispness and transparency of sound that characterizes its forerunners. As our oscilloscope tests have shown, sound pressure waveforms of musical instruments played through the Linear Phase system mirror almost exactly the original waveforms. This remarkable technological achievement came only after months of patient research by teams of dedicated audio specialists. The important elements of balanced tonality, finely etched transient response and excellent stereo imaging are all there, contributing tot a very convincing impression of live music.
Optimum speaker location By precisely aligning the acoustical centers of the speaker units and placing them physically as close together (while keeping them acoustically isolated). Technics engineers have succeeded in attaining phase linearity with even sound distribution. Moreover, the location of the units is finely tuned to compensate for slight phase shift in the crossover region. You will notice that the woofer is placed well away from the floor level to reduce boomy floor effects.
Vented Design for bass extension with excellent Power Handling
The SB-4000 is perfectly at ease handling Power up to 75 watts . And the High 91 dB efficiency assures ample volume, even with low power input. A surprisingly rich, solid bass response is achieved with a carefully tuned vented cabinet.
