multicellular horn การใช้

• A horn throat from the 801 penetrated the center of the LF field coil and exited into a small multicellular horn mounted in front of the LF cone.
• Products included " biflex " speakers where frequency range was increased by a flexible " decoupling " of a small center area of the speaker's cone from a larger " woofer " area; the 604-series of coaxial speakers employed a high efficiency compression driver mounted to the rear of the 604's low-frequency magnet, and exited through a multicellular horn that passed through center of the woofer's cone.
