What Dynaco a25 are these?

[DW617]

Who knows the answer?
I just picked a pair of a25, however it doesn’t look like the ones on ebay. The logo is not on the bottom left, the inside is not black, its red cardboard material , the tweeter is on the upper right, but has 8 screws not 4 ( I suspect its replacement) . The grill is also glued on.
I also upload 2 pictures of the ones for sale on ebay for reference.

The first ones are one of the two common A25 speakers, SEAS drivers bottom port. Are those the ones you question?

 

[DW617]

Yes, the first picture with the highlights. Are these the first versions? Do different version sound different?

scanspeak or seas seem to sound close to the same.
early ones had top vents (well low production number don't know when)
You have most excellent standard A25 without any issues that make them weird and more or less desirable depending on who is looking, variety collector or just an A25 buyer that wants a nice pair that can be repaired as needed.
Some prefer one set of drivers over the others but I don't recall which and since I've had both don't have a preference.

Thanks for the info. I notice the sound is louder on the left speaker. Do you think something is wrong with my Yamaha cr-840?

Swap speakers and see if the volume follows the speaker or the wire from the Yamaha
