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-530 loudspeakers

Bookshelf speakers with the perfect mirror-image sound
Here is truly a remarkable achievement in loudspeaker design and performance. The Koss CM/530 bookshelf loudspeaker sets an entirely new standard in extended bandwidth response, high efficiency, low distortion and perfect mirror-image for speakers in its size and price range and within today's technological capabilities.
By designing a left and a right channel configurationfor the passive radiaator, the woofer and the tweeter, Koss engineers have created a perfectly matched set of bookshelf speakers that can be placed horizontally or vertically without losing the perfect right to left imaging, an incredible degree of dispersion and the beautiful sound of Koss.
To create the breathtaking depth and clarity in the CM/530, Koss engineers used an 8-inch passive radiator to radiate the sound energy over the lower two octaves. This allowed them to use an 8-inch woofer to reproduce the critical sounds in the midrange up to 3,000 Hz. In addition, the CM/530's 1-inch dome tweeter reproduces an exceptionally flat energy output and unusually low distortion that provides for a transparency and liveliness not found in other competitive speakers.
The Koss CM/530's also offer an unmatched increase in dynamic range over competitive bookshelf speakers. Due to the CM/530's higher efficiency and lower distortion, you can hear the higher sound pressure levels without clipping and also hear the lowest bass with a dramatic clarity as well. And to help you shape the extra sound you'll hear, there's a 3-position Tweeter level Control switch on each speaker that allows you to alter the tweeter frequency spectrum from a flat response to ±3 dB.
