Castle Avon 1 Speakers

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