Bought a pair of dynaco a25 a few days ago, for $25, I dont know why but curiosity got the better of me,if I dont like them I could always sell them or blow them up with my bass guitar.If your not familiar with them they use seas drivers One dome tweeter and a 10"woofer. a super simple cap and resistor crossover for the tweeter.the enclosure is an aperiodic design which seems to be a fancy name for a ported speaker where the port is mostly stuffed with insulation.This is a good thing since this is long before they learned to make bass reflex speaker that where tuned properly.
Firstly these are speakers designed in the late 60's so its unfair to review them by todays standards.there is no deep rumbling bass but plenty for jazz or rock even though the bass isnt of very good quality.the top end is mellow but very good,you turn up or down the tweeter with the 5 way switch in back .turning up the tweeter gives more air but makes the upper mids a little too metallic for my taste.I have found that speakers with simple crossovers can give you very good imaging, and these did a good job but did not do better than any modern speaker today could.I also think the 10"woofer was bad idea, its a little bit too big to handle the midrange well and you hear it in female vocals if you turn it up.
patricia barbers cafe blue cd sounded good, its a mellow jazz cd that seems to fit the style of these speakers.
unfortunately these speaker failed with claudia gomez salamandra this is a hyper detailed binaural recording on the clarity label.It just sounded dead.
of course i had to use the old workhorse rebecca pidgens the raven.in the song seven hours you can clearly hear her and the male background singer.you would be surprised how many speaker(even some expensive ones) blur them together.
the last cd were some of my binaural recording I have made.they are pure with no compression or EQ or processing of any kind and Im sorry to say they just cant handle the transients.everything had a thick film on it, I blame the 10" woofer for that.
overall I cant complain too much Im sure these were amazing speakers for their time.
