In terms of?
Sonics? Performance? Restoration costs? Resale value?
These were a $2500-$3000 speaker when new in 1978. Putting that in today's dollars brings it to around the $9000 mark. You can expect it to perform with the likes of modern speakers in this price range (although I do admit, modern speakers have superior treble response and detail resolve in general). They have a "rightness" to the sound that is a challenge to find in any speaker. They are highly involving and compelling, sounding natural yet exciting and dramatic when called for. Plus you can't beat that open sounding transmission line bass. I still have yet to hear a better bass from a speaker or subwoofer alike.
Plus these are classics and are a joy to own and gaze upon. Not to mention fairly uncommon!
