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.

Goodmans Axiette 8

 Here is the new model of the world famous Axiette - smallest true high fidelity loudspeaker produced.
The Axiette 8 retains the best features of the original Axiette: teh unique hyperbolic diaphragm, plastic terminated, and aluminum drive coil. In addition, it features a new and brilliantly conceived die-cast chassis whose unitary design retains all parts in precise alignmentt. The slender lines of the Axiette 8 are made possible by the use of a cmpletely new magnet system with a Feroba II permanent magnet.
Feroba II is a high efficiency anisotropic sintered material whose properties enable considerable reduction in magnet assembly depth.
The Axiette 8 requires an enclosure volume of only 3,000 cubic inches. Thus it can be used  i the most compact installations, while its power handling capability of 6 watts is more than adequate for many domestic systems.
 Features:
Smallest true high fidelity loudspeaker madde
New precision built diecast chassis brilliantly designed, with up-to-date slim profile
Completely new magnet system incorporating Feroba II permanent magnet
Designed and produced by goodmans -- with 35 years' experience in this highly specialised industry
Enclosure volume requirement only 3,000 cu. In.
Specifications:
Frequency Range:  40 - 15,000 Hz
For Amplifiers Up To:  6 watts (12 watts USA)
Fundamental Resonance:  65c/s
Flux Density:  13,500 Gauss
Total Flux:  53,000 Maxwells
Voice Coil:  1' diameter aluminium
Impedance:  15/16 Ω
Chassis: Diecast
Baffle Hole Diameter:  178 mm (7")
Overall Diameter:  210 mm (8-9/32")
Overall Depth:  92 mm (3-5/8")
Nett Weight:  1,81 kg (4 lbs)

Goodmans Triaxiom 212

 Need proff of the clear, clean, true sound reproduction of a loudspeaker by Goodmans. First, check the response curves charted below.
They dramatically reveal the smooth, undistorted frequency response over the audio spectrum. Translated into musical terms, the Goodmans speaker reproduces sound with proper balance, clarity and realism … achieving perfect separation of instruments, peak-free highs and well-defined, clear bass tones. This quality instrument is the perfect example of British precision and craftsmanship.
One of the many outstanding custom features on all goodmans speaker is the "Rigid-Flex" cone … a completely flexible, free-floating cone rim and completely rigid cone center to provide pure piston action.
Triaxiom 212 Features:
Finest value ever offered in an integrated 12" three-way loudspeaker.
Extra-heavy, high-efficient magnets for maximum performance.
Smooth, undistorted response from 20 to 20,000 Hz.
Unusually sturdy construction with rigid, die-cast chassis.
Power handling capacity is 25 watts
Total flux is 178,000 Maxwells.

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.
