Avon Series, with breakthrough Twin Drive Transmission Line technology, combined with natural wood veneers, handcrafted and polished to perfection – Castle Avon is a delight to both eyes and ears.

Determined to perfect and take advantage of the Transmission Line speaker principles, Castle engineers conducted a three-year investigation into the acoustics, mathematics, and all performance aspects of such loudspeakers. The result was a breakthrough in TL Theory. In its simplest explanation, driving the line at two distinct points overcomes both the damping problem and energy loss, resulting in a smooth power response from the lowest fundamentals to the midrange frequencies.

Castle has called this breakthrough technology TDTL – Twin Drive Transmission Line and is in the new Avon floor-standing loudspeakers for the first time.
