Technics SB-7000


The Technics SB-7000 speaker system has been designed to convert musical wave forms applied to the speaker to sound waves with extremely high fidelity, in other words, to make the transfer function of the speaker system is unity.

Even though musical wave forms are complex, they are merely a composition of various kinds of pitch components, each with it's own individual amplitude and phase characteristic.

Therefore, in order to have a faithful reproduction of the musical wave form applied to the speaker system, not only the amplitude (sound pressure level)/ frequency response of the speaker system, but also the phase/frequency response, must be flat.

Technics has developed a phase-measurement system which employs a delay unit using a Bucket Brigade Device. This system permits accurate analysis of the speaker phase and, as a result, a new crossover network and high performance wide-range drivers and their ideal positioning are used to flatten both the amplitude/ frequency response and the phase/frequency response.
