With breakthrough Twin Drive Transmission Line technology, combined with real wood veneers, hand crafted and polished to perfection - Castle Avon is a delight to both eyes and ears.
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.
Castle has called this breakthrough technology TDTL - Twin Drive Transmission Line and is, for the very first time, in the new Avon floorstanding loudspeakers.
Avon 4 features twin castle 130m woven fibre cone drives in a TL tuned to 38Hz, while Avon 5 features twin castle 150mm Woven Carbon Fibre cone drivers in a TL tuned to 32Hz. In room the Avon 5 achieves a bass extension (-6dB) down to 30Hz making it a truly wideband speaker.
