One woofer is seized up and will need replacing .
Bottoms of cabinets are not pretty like the tops and sides .
Not interested in offers or trades price is firm . I’m in Ct .
The A-50 is a slimline consolette 3-speaker system which advances the aperiodic design concept initiated in the A-25.
The two 10" woofers provide 1/3 more radiating area than a 12" cone, avoid mechanical instability problems, and provide a smoother crossover to the tweeter at 1000 Hz.
This non-rigid hemispheric tweeter has somewhat wider range and considerably greater power handling capacity than the A-25's high frequency driver.
The internal cabinet structure is unique. Two separate chambers provide dual spectrum damping - a combination of ideal damping in the range of cone resonance, plus the benefits of a larger sealed enclosure in maintaining linearity in the lowest bass region.
The two woofers are mounted in one chamber, which is vented through an acoustic impedance system into the second sealed chamber.
This variable volume action of the aperiodic design lowers the Q of the system, and preserves an even more linear impedance characteristic than is achieved in the A-25.
The result is notably superior transient response (articulation) in the bass range.
