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.

Monitor Audio R 100

 Monitor Audio, located in Cambridge England, was formed in 1972 by Molqbal. His intention was simply to produce cosmetically appeealing loudspeakers that accurately reproduce music while representing value for money.
M.Q. Cabinets Limited, Monitor Audio's cabinet manufacturing facility, was established in 1976, allowing Monitor Audio to fully control the quality of workmanship that goes into every pair of their loudspeakers. M.Q. Cabinets rapidly estabilished an impressive reputation for the quality of their solid wood and real wood veneered cabinets. So much so that they have produced or currently produce, cabinets for every well known (and not so well known) British loudspeaker manufacturer.
However, it is sound quality that is Monitor Audio's raison d'être. Committed to pushing the understanding of loudspeaker technology forward, Monitor Audio have ready access to anechoic and other test facilities at G.E.C. and Cambridge University. Their new metal-dome tweeter is an example of this commitment. In several respects this unit is significantly more advanced than competitor's comparable tweeters. It is a full size 25 mm, metal dome made from aluminum with the dome and coil former formed as one piece. High temperature wiring is used and the tweeter is vented in four places. It is additionally ferrofluid cooled and damped leading to an increasse of up to 30% in power handling. This is the first fully suspended metal dome, and as such, works much like a normal non-metal tweeter, without the inherent distortion but with the benefit of high efficiency levels and power handling capabilities.

The use of Nitrile in their woofer assembly is also leading the way. This material developed by NASA has, as its property, the ability to remain unaffected by climatic changes. As the temperatures and humidity of the listening room changes the loudspeakers maintain a level of consistent sound quality.

Critically acclaimed designs, state-of-the-art. Materials and technology, and a finished product fit to grace the finest surroundings need to be incorporated with an eye for detail to ensure an equal level of sound quality. T-bolts are used to mount the drivers into the cabinets securely. Speaker grilles have bevelled edges to ensure minimal defraction and consequent distortion of the sound. Optional stands are available which ensure the correct height from the floor is obtained achieving an accurate tonal balance from the speaker. But when all is said and done the proof is in the pudding. Simply select a model that siuts your requirements and listen. You'll be convinced that Monitor Audio is truely the symbol of quality.

Monitor Audio R100
The R100 is a simple two-way enclosure design, utilizing a 1 inch soft dome tweeter and 8 inch woofer.
You will be immediately impressed by the fact that even in this price range Monitor Audio use real wood veneers, making the R100 a beautiful piece of furniture.
Special attention is paid to components and construction to ensure the R100 sounds as good as it looks. The speaker is internally braced for rigidity thus reducing colourations that vibrating cabinets can add to the music. To this end, cabinet resonances are further damped with an acoustic foam lining.
 A simple four element crossover that matches the woofer to the tweeter is hardwired using Monitor Audio's own multistrand cable.
This minimal crossover ensures high efficiency and low distortion, as the musical signal is not required to negotiate a complicated network of electrical elements.
The result is an undemanding loudspeaker that doesn't require high power to produce an articulate, detailed and dynamic sound.
