Aperiodic Loudspeaker System (1971)
The Dynaco A-25 aperiodic loudspeaker is a compact, high performance two way speaker system.
A 10 inch extended excursion woofer is matched to a specially designed soft dome tweeter with a dual section high pass filter at 1500Hz, in a cabinet design which achieves a uniquely non-resonant bass response.
The aperiodic, or non-resonant characteristic of the A-25 provides an unusally uniform impedance characteristic throughtout the bass range of less than 2 in 1.
This design utilises an acoustic impedance system which provides variable volume action rather than the totally enclosed cabinet of the acoustic suspension principle or the tuned port of the bass reflex.
