The Spica Angelus furthered the state of the art in dynamic speaker system performance. Featuring exceptional spatial resolution, neutral tonal balance, and a unique and attractive shape. Like its forerunner the TC-50, the Angelus evolved from a combination of advanced theoretical work and years of experience in sound reproduction. It is another major step toward the realization of holographic imaging in stereo reproduction.
The Angelus, dedicated by its designer John Bau to the memory of Richard Heyser.
