THESE ARE IN NEAR MINT CONDITION WITH MINOR SCRATCHES ON THE BOTTOM OF THE CABINET. 100% WORKING.
__________________These are a special version of the classic Dynaco A-25 manufactured by the Panor Corp whom bought Dynaco. The MSRP on these in 1998 was than 600,000 A-25s have been sold since its premiere. This Dynaco value leader clearly ranks as the most popular quality speaker of all time. First it was listened to with doubt of its pretentious claims, then with awe for its performance; later with admiration for its listening ease; and finally with respect by the host of copiers it engendered.
This acceptance prompted Dynaco to develop other models which represented refinements of sonic quality or application to meet a variety of needs and personal tastes. In contrast to some loudspeaker lines which apparently strive for a different sound from each model, the sonic characters of all Dynaco speakers are very closely related. All of our designs stress clarity, smoothness, precision, and above all, value.
Since the continuing design intent is literal translation of the original performance, or verbatim reproduction, the casual listener at first may perceive no differences between some models at moderate sound levels. Careful listening, which is most important when choosing any speaker system, will elicit the distinctions which brought about successive designs. Yet the original A-25 has not been found wanting in this comparison.
Every loudspeaker design represents some compromises, and it is in weighing the designer\'s choice against the listener\'s ear and wallet that success is determined. Dynaco has concentrated its attention on smoothness of response, delineation of detail, cohesiveness of image, sensible efficiency and reasonable power handling capability. The cost had to be low to assure the evident value from the outset, so that high sales volume would facilitate production efficiencies to continue this record. The A-25 was introduced when Dynaco felt that it had achieved a sonic balance which, in comparison with speakers two and three times its cost, fulfilled most listening requirements in a true bookshelf size at well under $100.00.
How well we succeeded is indicated by Gordon Holt\'s statement in Stereophile magazine. \"You will have a hard time buying more musical naturalness at any price... (the A-25s) are quite probably the best buy in high fidelity today.\" As Julian Hirsch commented in Stereo Review, \"When the music contained low bass... the Dynaco (A-25) left no doubt of its capabilities... Nothing we tested had a better overall transient response.\" And Audio magazine echoed, \"The A-25 produced the finest tone-burst response of any speaker tested in this manner, regardless of price.\"
The various Dyna models are remarkably similar on close examination. That\'s only logical, in light of the original design\'s manifest success. There may be differences of detail in the drivers which may not be superficially apparent. Or, the crossover networks may differ (the crossover frequency is but one aspect). Even structural differences in the cabinets have a decisive bearing on sonic refinements. Since differences in speakers are not readily quantified, and are largely subjective, Dynaco has exerted its expertise where the results are most apparent.
All Dynaco speakers are two-way systems (the A-50 employs two identical woofers) to avoid the problems of complex crossovers, and to minimize the effects of different drivers reproducing the same frequencies. While the ideal reproducer would be a unified source, physical limitations preclude this in practical systems. Careful tailoring of Dynaco drivers for integral rolloff characteristics eliminates the need for elaborate networks, assures smooth mid-range transition, and minimizes time-delay and phase distortion.
A single high power wide-range tweeter provides sonic homogeneity and excellent dispersion with minimal interference effects. We use a non-rigid dome which is specially treated to reduce cavity resonance effects. Wherever possible, it is located near the center of the panel to minimize edge interference aberrations.
Extensive investigation has shown that a 10\" woofer affords the optimum combination of low frequency generating capability, low moving mass, and adequate structural rigidity to avoid cone breakup for a smoother mid-range blending.
