Which tweeter in my A25's

Which drivers in my A25's

How do I tell which drivers my Dynaco A25's have? Seas or scanspeak?

Nobody knows?

My a25's had plastic rings around the scanspeaks, I bought a seas replacement for one of them, and it didn't have the ring. Hope that helps.

Could be one or the other--

"Dynaco speakers were designed using Seas drivers, and imported to the USA under the Dynaco name. Interestingly the earliest A-25's used ScanSpeak Drivers and had the Aperiodic Port above the Tweeter, but this was soon changed to the widely seen Seas Drivers and the port under the woofer."

A picture would have helped a bit, but there ya go

I noticed that the port is under my Woofer. Does that guarantee they are Seas drivers? It doesn't really matter to me but I had listed my A25's for sale and a prospective buyer wanted to know if they were the seas drivers and only wanted them if they were. In the end I decided not to sell them and just hang on to them. But curiosity has me wondering if they are Seas or scanspeak.
I'll post a pic tonight.

I wouldn't guarantee that they are original... parts being replaced seem like a fairly common practice with the A-25s. Some folks put the Morel MDT20 tweeters in as an upgrade. Pulling the units and looking up the code printed on the back, and/or looking at the woofer rubber surround can yield a number that may be traceable on the interwebs!

The speaker codes can be found here: http://www.webervst.com/morecode.html I do believe they are accurate. Hope this helps OOps... no seas or scanspeak there... sorry!

Nice tidbit of knowledge there!:thmbsp:

I'll have a set of A25s apart shortly, I'll post photographs of the drivers. These are bottom port cabinets (apparently the later style of cabinet) and I believe the drivers are original but cannot be sure of that. Earlier this week I posted some similar questions about driver manufacturers and cabinet styles and Dynacophil replied with a seemingly knowledgable post... here's the short thread.

Thanks JonL. I'll look forward to your pics.

You need to post photos of your speakers. That's the only way for us to know for sure.
