Interesting finding with Dynaco A-25 woofer

Vintage Asylum

Classic gear from yesteryear; vintage audio standing the test of time.

The Seas 23FE-W used in the A-25 specs out for an optimal cabinet size of 3.5 cubic feet with a port. The original cabinet is less than 0.7 with an aperiodic vent. Yes it is true you do get a better F3 with a vent and tighter bass with a closed. The aperiodic vent seem to strick a good balance between both worlds with this woofer.
I had some extra cabinets kicking around, a 1.5 cubic foot with a rectanglar vent. I put in the drivers and couldn't believe what that woofer was capable of. If the original cabinet was a mere few inches bigger This speaker would blow your socks off. It's almost a shame the original selling point design was for such a small box.
Next month I'm going to try a 2.5 or maybe a 3.5 cubic cabinet and see if the difference continues.
