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.

Koss CM-1010 loudspeaker


No other 2 bandbass speaker system can match the CM/1010's extended bandwidth response, high efficiency and unbelievably low distortion performance. And that's true at any size and at any price range. Once you've heard the unequaled Sound of koss in the CM/1010 you'll know for certain that our computerized Koss theory helped to make the optimum 2 bandpass speaker a reality. The CM/1010's unique passive radiator enhances the lower two octaves of the bass and allows for the use of a specially-designed 8-inch woofer to reproduce the critical midrange. A high-energy 1-inch dome tweeter produces the high-est energy output and lowest distortion of aany tweeter currently available. And an exclusive crossover network adds the finishing touches to the finest 2 band-pass loudspeaker system available today.
