  • Lowther PM6 Mk. 1 Drive Unit

    The special design of the PM6 drive unit preserves the fundamental harmonic relationship throughout the entire audio range, thereby ensuring smooth, natural sound. Designed especially to meet the requirements of horn-loaded operation, the PM 6 should never be used as a conventional direct radiator.

    PM6 Mk. 1 is a PM6 magnet assembly with a new diaphragm assembly incorporating a Lowther special silver speech coil, roll surround, and back centering providing improved performance.
