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.

Cerwin-Vega 211R

Cerwin-Vega Features:
Smooth, extended response, low coloration, and good dispersion across the entire audio spectrum
High Efficiency Design - 4 to 10 times more output per watt than competing systems
Enormous Flux Densities for quick precisely damped transient response and accurate reproduction of subtle musical textures
High Energy components with up to 10 dB more undistorted output capability than other systems
"Infrasonic" Back wave tuning for optimum bass coupling to listening room
Circuit Breaker of fuse protection of all hi-frequency drivers.

Inside Design:
Bass you can feel - Cervin-Vega woofers combine high efficiency and high power handling ability for more low-distortion output below 50 Hz and quicker transient attack than sluggish acoustic suspension units.
Crisp, Accurate highs - Our exclusive dhorm tweeters feature extremely high flux densities and low mass diaphragms. The result  - superior transient response and flat evenly dispersed output to beyond 20 kHz
Controllable Imaging - A reflective mid-hi horn in the 211R adds spatial dimension and presence, eliminates "holes" due to poor room acoustics.
Unique "Infasonic" Tuning - basic enclosure resonce of 5-10 Hz eliminates response peaks and "boom" from the audible range.

Outside design
Rugged components - Extra heavy frames and specially treated cones and voice coils maintain flawless performance under demanding use.
Quality cabinets - All cabinets are premium hardwood on hi-density 3/4" particle board, with solid inlays and hand rubbed natural oil finishes for lasting beauty and easy maintenance.
Easy component access - Snap-on grille (except 24) and removable cabinet back allow field-replacement of all components
Adjustable balance - Rotary crossover controls allow precise tailoring of high frequency balance to suit any room and any music. (fixed crossover on 24)
