Vienna Acoustics speakers help

Pull the midrange driver out and hook it up to an amp directly then work backwards towards the crossover network to see where signal is lost.

There might be a fuse in the crossover?

Are the jumpers on speaker terminals installed?  If it is a bi wire speaker, that would account for it.

beethovens don't have dual binding posts. I think you're going to have pull the drivers and test them with a multimeter.

I really doubt those speakers have internal fuses. Check drivers individually but be careful. Use an ohmmeter to check resistance first before checking audibly. They are not bi-wired, no jumpers.

After multimeter test, I got no ohm reading. I think both speakers midrange drivers and tweeters are toasted. Thanks for everyone help.

Hope you can work it out with the seller, though it sounds like they have skipped town.  If you end up trying to repair these, keep an eye on eBay.  I see random NOS parts (drivers, crossovers, brackets, etc.) listed frequently.  Also it appears that VA shared some components between the Bach, Mozart, Waltz, Beethoven, and possibly other models from that era (Theatro, Maestro, maybe even Haydn?)  So you might find some suitable parts donor speakers for cheap.  But they did have small changes throughout the years as they went from the original designs to the "Concert Grand" and "SE"/"Symphony Edition" so you'll have to verify compatibility somehow.  

There are also licensed distributors that can obtain repair parts from Vienna.  I went through Bluebird to get some VA parts a few years ago.  

Sorry to say, Can you find values for the xover? even replacing drivers might result in disaster. If the seller doesn't make good please post everything you can about him/her.
