With breakthrough Twin Drive
Transmission Line technology,
combined with real wood veneers,
hand crafted and polished to
perfection - Castle Avon 4 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 loud-
speakers. 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 fun-
damentals 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 4 floor standing loudspeaker.The Avon ribbon tweeter design uses an ultra-thin alloy
sandwich precisely positioned in a powerful transverse
magnetic field, where the ribbon acts as both the voice
coil and diaphragm. In this way the whole radiating area
is driven directly and responds accurately to the music
signal. Together, the direct drive and low mass of the ribbon
provide superb musical detailing and transient attack, re-
solving the harmonic content of the music in a thrilling and
natural way.Available in either Black or Cherry finish the Avon 4 looks
great, which is a bonus, but in the end it’s all about the
music – so come look and listen for yourself.A Feast for the
Ears and Eyes

“The dry, low bass of the transmission
line better resolved the character of
the bass instruments than just about
any loudspeaker I’ve heard before.”
