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.

Axiom 80 for Goodmans

The Goodmans Axiom 80 is a 10-inch, twin-cone, full range loudspeaker, whose performance, in a prpoer enclosure is as astounding as its unique design.

The most revolutionary advance embodied in the Axiom 80 is its achievement of free cone suspension - the theroretical ideal that permits the cone to move as a true piston at low frequencies, without restriction and without distortion.

Another direct result is that the fundamental resonance of the Axiom 80 is only 20 cycles - lower than that of any other commercially available loudspeaker.

The new ARU Friction Loaded Enclosure represents the perfect solution to the enclosure requirements of this superb reproducer. The axiom 80, mounted in a Model C-1800 ARU Enclosure, will reproduce true bass fundamentals down to 20 cycles - with no "hang-over" and without peaks above that frequency. Mid-range reproduction is clean and articulate and the :highs" smooth to 20,000 cycles. All of this is accomplished without the use of special "tweeters" and elaborate crossover networks.

Power handling capacity of the single Axiom 80/ARU system is entirely siutable for use in most home systems (8 -12 watts, continuous program material: 4 -6 watts , RMS sine wave). Where greater power handling is desired, two Axiom 80 loudspeakers may be used together in the Model B-2800 ARU Enclosure or four may be used in the Model A-4800.

No multi channel system, however elaborate or costly, cansurpass in performance these dual and quadruple Axiom 80/ARU systems.

ARU Enclosures are now available in easy-to-assemble kits, supplied complete with the necessary precut lumber, grille cloth, padding, glue, hardware and the all-important ARU Acoustical Resistance Unit.

Astounding performance from 2o to 20,000 cycles with a single channel speaker system.
