Castle AVON 4 Floor-Standing Speaker in Black (Pair - Demo)

The 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 embarked on 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 the damping problem and energy loss, resulting in a smooth power response from the lowest fundamentals to the mid-range frequencies.

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

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. The Avon 5 achieves a bass extension (-6dB) down to 30Hz in the room, making it a genuinely wideband speaker.

The Avon Series provides delicacy and sparkling detail in reproducing musical instruments and voices.

Avon Series does not just focus solely on the TDTL Transmission Line technology.

In addition to the Avon 4 and 5-floor standers are the Avon 1 and the Avon 2 bookshelf speakers and the Avon C centre-channel speaker. You can configure Avon speakers for conventional stereo systems and full-home cinema setups. The other speakers in the series use a combination of Single Drive Extended Line and Twin Drive Extended Line technology for a dramatic sound. 

To equally match the low-end clarity of the TDTL technology, all Avon speakers are paired with an advanced Ribbon HF.

Avon's ribbon tweeter design uses an ultra-thin alloy sandwich precisely positioned in a strong transverse magnetic field, where the ribbon acts as both the voice coil and diaphragm. This way, the radiating area is driven directly and responds accurately to the music signal without energy storage or breakup. Together, the direct drive and low mass of the ribbon provide superb musical detailing and transient attack, resolving the harmonic content of the music thrillingly and naturally.
