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.

 A new loudspeakers of advanced design suitable for stuio use and for home installations of the highest quality.
Even the cabinet's distinctive visual design contributes to your listening enjoyment. Its tall, slender silhouette permits maximum enclosure volume in minimum floor space (only 1.2 square feet), while aligning the upper frequency drivers more directly with the usual listening level.

 Driver units
HF 2000 - dome "pressure" type
MF 500 -  Mid-range dome "pressure" type
Within the cabinet are a superbly matched set of drivers and the Auxiliary Bass Radiator, all aligned on a single vertical axis to minimize diffraction effects. High frequencies are handled by the HF2000 tweeter (specified by the B.B.C. for monitor use).
The mid-range driver is the pressure-dome MD500. And for the bass, a combination of the FC12 bass unit and 12 inch A.B.R. (Auxiliary Bass Radiator) together with the carefully damped enclosure form an acoustic circuit that operates smoothly to frequencies well below 40 Hz.
The crossover has resulted from considerable research and crossover points are at 500 Hz and 5000 Hz, 80 watts maximum. 4 - 8 ohm. This monitor loudspeaker system has an exeptionally wide and flat, frequency respponse. Very low order harmonic and intermodulation distortion. Precise response to transients. Beautifully maintained polar response ensures absenc of unwanted directionall effects and provides a highly satisfactory stereo image throughout the listtening area.
