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.

Thiel CS.5 speakers

The CS.5 is a Two-way ported, floor-standing loudspeaker offering high performance in a compact, easy-to-place cabinet and at an entry-level price. Completely time and phase coherent, the CS.5 provides a dimension of clarity and realism that conventional speakers in its price class cannot achieve, making it ideal for both music and video sound.
The CS.5 incorporates many of the same design techniques used in other Thiel, speakers to achieve our goal of accurate musical reproduction in all areas of performance. The drivers are positioned along a sloping front baffle for correct time alignment, and the crossover is designed to provide phase accurate transitions between the drivers. These two design features alone result in an unusually high level of spatial and transient fidelity for a speaker of this price. A specially shaped grillboard decreases diffraction for more open sound, and the heavy cabinet construction reduces unwanted vibration to improve clarity and imaging.

Quality construction and materials.
The CS.5 uses the same quality materials as the more expensive Thiel models - a die cast magnesium woofer chassis, polypropylene or polystyrene capacitors, and rigid 1-inch thick cabinet walls.
Tweeter
The 1-inch metal dome tweeter uses a large magnet, vented pole, and reinforced rear chamber to allow a low resonance frequency and a wide bandwidth. The result is high frequency reproduction of great clarity and realism.
Woofer
The Thiel-designed 6,5-inch, treated paper cone woofer incorporates the same short coil/long gap motor design as other Thiel woofers for low distortion, very good midrange performance, and clean bass response. The woofer is magnetically shielded to prevent video image distortion.
