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.

Electro-Voice 15TRX loudspeaker

Incorporating all the design advantages of the famous Electro-Voice Radax Coaxial principle, the 15TRX and 15TRXB integrated 3-ay loudspeakers include, also, the latest developments in the art. Of reproducing the highhest audible frequencies through the use of integral Super Sonax VHF drivers. Bass response is excellent, affording pleasing musical balance without the masking effects often experienced from extended high-frequency reproduction.

Both the 15TRX and 15TRXB loudspeakers are tailored to optimum listening requirements; latest developments incorporated insure uniform, smooth coverage of the entire listening area. The engineered features of these E-V integrated 3-way speakers include true concentric mounting of all reproducing elements; augmented balanced bass response in conjunction; carefully tailored mid-range characteristic to provide realism and a considerable degree of "presence" at usual sound levels.


Further benefits are afforded in the high-frequency section of the Electro-Voice integrated 3-way speakers by the incorporation of E-V developed diffraction horns to achieve the best dispersion. An adjustable "brilliance" control is incorporated to allow matching of response to room acoustic, compensating for high-frequency absorptive effects of heavy draperies and soft furnishings. A true 2-way electrical crossover network minimizes distortion, and a massive ceramic magnet assembly provides highest efficiency, excellent damping and extended range.

Electro-Voice 15TRXB loudspeaker


Both the 15TRXB and 15TRX incorporate the exclusive Sonophase throat design in the high-frequency section. The importance of the Sonophase throat is paramount above 12 kHz where sound must be taken from the center of the diaphragm and periphery simultaneously. In this design this is accomplished without destructive interference or cancellation within the sound chamber.

Bozak Celestovox B-1207 speakers

Bozak Celestovox Speaker System , model B-1207

One of great deterrents to reproducing music in the home so that it has the fullness of dimension which characterizes concert hall listening lies in the size of the typical home listening room.

In the vast space of the concert hall, sound revererates from wall and ceiling surfaces there is a finite interval between the time that the direct sound impinges on the ear and the time that the reflected waves reach the listener. In the home situation, reflected sound reaches the ear almost simultaneously with the direct sound, hence there is no feeling of spaciousness.

Bozak engineers have devised a system which so nearly, simulates concert hall conditions in the living room that a whole new dimension is added to home listening. It consists of the Bozak Model 900 Celeste Time Delay and the Model B-1207 Celestovox loudspeaker system especially designed to provide ambience by reflecting sound from flat wall and ceiling surfaces.

 

Driven by a separate 25-watt or greater stereo amplifier, a pair of Celestovox's can add the excitement of concert hall ambience to your own listening room. Strangely enough, the sound is so natural that you may be unaware of the enhancement unless you switch off the Celestovox speakers, then your ears will quickly detect the lack of ambience.

 

Since the Celestovox speaker system operates by reflecting off flat wall surfaces there is complete flexibility with regard to speaker location within a room. There is no need for corner placement, since front projection is not required, the Celestovox can be placed behind furniture. Exact location in a particular room can best be established by trial.

In the concert hall, high frequencies are naturally attenuated more rapidy than lows. Celestovox incorporates a high frequency roll-off control to permit adjustment to room acoustics and personal taste.
