What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Castle Tay loudspeakers

The Castle Tay has successfully taken over from the best-selling Castle Durham which it replaces. Optimally designed for stand or shelf applications in medium sized room, the Tay delivers a bass impact which belies its size.

Key to this performance is a specially developed version of the latest Castle 130 mm mid/bass driver. A high performance motor system was developed for the Tay by employing a higher power 1,2 Tesla magnet and a special long-throw voice coil wound on a high temperature Kapton former. Critically damped reflex loading with a radiused port ring gives low distortion bass performance of true power and scale.

High frequencies are handled by the highly praised Castle 25 mm soft dome tweeter crossed over through the easy amplifier load of a 2nd/3rd order network. The Tay delivers smooth and extended bass of considerable power and detail.

Castle Eden loudspeakers

The innovative Eden is the largest Castle speaker for stand or shelf mounting. It takes the unique woven carbon fibre diaphragm technology, developed for the floor standing Castle Avon, and uses it to staggering effect in a compact enclosure.

Heart of the Eden's acoustic system is the latest in bass drive unit construction. Castle's new die-cast chassis 170 mm mid/bass drive unit uses a cone made from long woven, resin-set and baked carbon fibres. This material offers unprecedented rigidity coupled with low weight. The speed and accuracy of this large drive unit are phenomenal. Yet its extended midrange clarity permits a simple 2nd order crossover network at 3,3 kHz that is both transparent and easy for an amplifier to drive.

Treble is handled by the outstanding Castle 25 mm polyamide dome tweeter. The marriage of these two advanced drive units creates a sound quality that offers exceptional transparency, detail and astonishing dynamics. Stereo imagery too is solid and stable.
