Altec Lansing A7's 50's model


I am thinking about picking up a pair of these speakers. They are about 40 years old and in good condition according to the pictures. Can i get some feedbacks on the following topics?

1. The sonic signature of the A7's?
2. How much they worth?
3. Can they still be serviced?
4. How are they compare with modern speakers if this is a fair question?

Thanks for your help.

Altec still supplies parts(diaphragms/woofer re-coning kits) for the drivers to all their authorized repair/warranty stations. Waldom Electronics supplies re-coning shops everywhere, and parts that will make the woofer LOOK original, but it will lack the edge-wound aluminum voice-coil(and quite a bit of performance). SO- Yes, thet are easily serviced/supported. The sound: They're LOUD! Comparison with modern horn-loaded theatre systems: They're LOUD too! Some people like LOUD and don't mind the horn colorations/crazy response curves that go with these systems. If you can get them cheaply enough: See if they fit your tastes(they'll be great, if you have neighbors you hate, or for a home theatre system).
Here's a link to the system's PDF manual: (http://www.altecpro.com/pdfs/vintage/SpeakerAndMics/systems/A7-8G%20VOTT%20Speaker%20System%20Manual.pdf) and these guys do the authorized repairs: (www.greatplainsaudio.com)
