Altec "Stonehenge III" speakers from 1977 - Any Good?


Happy New Year all.

Wondered if anyone has experience and input on Altec Stonehenge III speakers?
They run $2800-$5000 condition dependent.
I have been wanting to make a great vintage system for my semi-finished basement.   Something rare-ish, historical,  but really good build quality and of course distinct sound. 
I know in general Altec was pretty incredible into the 80s, with the much larger Valencia, 604s, Model 17s, 19s etc. 

I would be driving with a PS Audio Pre-amp 5.5, a modified upgraded Adcom GFA-555 with a modified Bel Canto DAC 1 : so "all American". 
I have a British retro-system with a Rega Mira and Epos ES14 speakers, so there is a bit of reference for folks.

Many thanks!

I have the Stonehenge II's. They certainly aren't worth $2800 - $5000 - that's nuts! I paid a few hundred for the II's. The Altec Stonehenge series are very good rock/jazz speakers. Comparable to JBL.

@jasonbourne71 yea, seen a pair near me for $3500, faded front.  Seems nutz to me too, but then again I really have no true frame of 'value' for these vs the actual sound.  Do you find your bass/mid bass adequate?  That is the only thing I am finding from folks mentioning as a dislike (I think in comparison to other similar price or similar driver and speaker size units).

The Classic Altec sound is the 19's or the 17's Compression drivers.

Also owned the Large Jbl's  L300 ect

I now own the B&W 800 Matrix, in some ways Cannot Compare with the Large Altecs.

Did you get the Altecs?
