Altec A7 yay or nay?

Amp, source? Should we just take a punt and say “yes”?

I found that my A7s I dragged around  for PA use (mostly) from the early 70s well into the early 80s sounded amazing. Wooden...something...anyway mine were originally supplied with an Altec 15 which was just OK, but stick a JBL serious bass speaker like the D140 or later models in the things and you can do uncompressed bass slam to shake the neighborhood. I loved those things. 

Thanks guys for your input, much appreciated. It seems like a good deal even if they only end up in the garage. He did sell off the cones separately,  maybe made more money than selling the A7's as complete speakers one would imagine. 
As I have never heard a pair I do not know how they are with a Solid State amp as I am generally not to keen on tube amps, although I do have an very low hour Onix SP3 tube amp in its box somewhere. 
How are they with all types of music in a home setting?  I have read they are a bit bass shy, is that the case? I do have Klipschorns if I want the neighbors to hear my music and get the animals running for cover, lol....

I suggest buying a pair of JBL 2225 woofers (15 inch) for those Altec cabinets. I had a pair in large vintage JBL C - series cabinets. Can be found on EBay for less than $200/pair! 

Bass shy? Um.... No. They have plenty of bass output. It's just that they don't go real deep into the bass region. 40-45hz is just about it.  I had a pair of the home versions of  the A-7. Large squatty cabs with walnut finish (846-B). I loved those speakers. That was about 45 years ago. There's a pair on Audiogon right now I believe that are selling just south of $3000.

A company out there called Great Plains Audio makes and sells vintage drivers for all the older Altec's with compression drivers. They sell the woofers also. Probably not cheap, but you know the drivers will work properly if you buy from them.
