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.

Celestion CX 2012

 Celestion 12" Co-axial Loudspeaker
Handling 20 watts RMS and covering a frequency range of 30 Hz to 18 kHz, this loudspeaker has a moulded foam surround and a horn-loaded treble unit. This treble unit gives wide dispersion of the high frequencies and has a "brilliance" control so that the level can be adjusted to suit room conditions

1.Hi-Flex "free" surround - provides high compliance, eliminates standing waves and surround resonance. Guaranteed moisture resistant. 
2.Two Voice Coils - extra long bass voice coil and precision mounted H.F. coil ensure clean extended frequency coverage. 
3.Compression horn loaded treble unit - for linear and wide angle distribution of high frequencies.
4.High flux ceramic magnets - ensuring high input/output ratio
5.Pure electrical cross-over - provides smooth frequency transition and feed to the appropriate voice coil
6.Rigid die-cast chassis - giving permanent precision alignment
7.High Frequency level - or "brilliance" control allows adjustment of high frquency level to suit room conditions. Complete with 30" of cable, escutcheon and control knob
