A new midrange driver for loudspeakers

Introducing a new midrange driver for loudspeakers. The 777 rAMT Midrange Driver is the first of its kind, elevating the popular Air Motion Transformer (AMT) to perform as a true wide-range driver.

In the late 1960s, Dr. Oskar Heil developed a radically new AMT loudspeaker driver technology still widely-used to this day—but only in tweeter form. The 777 is the first mid-range driver to apply the technology successfully. Utilizing a curved diaphragm shape, it incorporates many benefits and features that make it uniquely suited for high-performance situations that demand power, reliability, and quality. This newly-patented technology is known as the Radial Air Motion Transformer (rAMT).

Behind its rugged, stackable design is a unique magnet and diaphragm assembly that results in a moving surface area nearly twice as large as conventional 10” drivers. The 777 achieves high output, high efficiency, and low distortion at high power levels. Across a range of listening environments, its proprietary design allows for the complete absence of cone-breakup and superb off-axis behavior at all frequencies. The type 777 will be available in 2022.
