Rediscover the legacy of the Dynaco A-25 speaker with our meticulously crafted replacement woofer.

We've strived to bring that sound back to the present with our replacement woofer, ensuring that you get to relive the magic of the Dynaco A-25 once more.


Aging Considerations and Modern Improvements

Lighter Cone, Higher Performance

 Our woofer boasts a light cone, that promises an improved transient response. This means that rapid changes in the music are accurately reproduced, giving you an unmatched audio experience, just as the original.

A Well-Designed Drop-in

We've taken care to ensure the woofer is fully compatible with the A25's aperiodic bass reflex port. This principal allowed the speaker to deliver deep bass from a relatively small enclosure beyond what was possible at the time. To do this we've reduced Re and Fs to underdamp the woofer ensuring exact performance when interacting with the air volume into the original A25 cabinet.
