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.

Pioneer CS-63DX speakers

A truly great speaker system can only be achieved by meticulously balancing three elements, speakers, crossover network and cabinet. All three of these elements are of the finest quality. Each has Pioneer's three decades of experience behind it. The result is a startlingly smooth response from 20 Hz - 22 kh. The CS-63DX works superbly with any amplifier or receiver; however, particularly excellent results are obtained with Pioneer's SX-1500T and SX-1000TD

 

Features of CS-63DX

Woofer

To reproduce low frequencies, large masses of air must be oved. There is no other way. Obviously an 8" speaker cannot move as much air as a 15" woofer. Pioneer's woofer features special cone paper and heavy magnet with more total flux than just about any other unit on the market today. Superb trtansient response results.

Mid-Range

For better wider dispersion in the mid-range and for a perfect match with the three exponential horn tweeters, we have used two mid-range units. Featuring a roll-edge cone for smooth linear excursions, these units have been carefully integrated into the totalsystem for just the right balance.

Tweeters

Many system use only tweeter someuse two, but Pioneer uses three for very good reasons. A tweeter that gives satisfactory dispesionusually cannot reproduce the extremely high frequencies efficiently. So Pioneer designed a horn tweeter for moderate highs, and two super tweeters for the critical ultra-highs. The result is more highs with a wider Dispersion than has been possible until now.

Tone Controls

No room is quite any other room.that is why a tone control is essential. By using this control to compensate for the particular acoustics of your room, optimum high fidelity reproduction is achieved. Pioneer's controls are unusually sophisticated. There are two, one for high and one for mid-range units. Each control has three positions, normal; increase; decrease. These controls are, in fact, desirable audio refinements.'

Crossover Network

This expensive crossover network assures that each speaker handles only those frequencies for which it was specially designed. From woofer to mid-range there is a gradual attenuation of 6 dB per octave, but for mid-range and tweeters there is a sharp 12 dB per octave attenuatiopn.

Cabinet

This master-crafted cabinet is fully lined with fiber glass and rigidly constructed to eliminated undesirable reflections and spurious resonance. Of infinite baffle design, the enclosure is finish ed in oiled walnut and features a most attractive grille. Here is a spacious enclosure that you can proudly place in any room.
