What used speakers raraely come up for sale


Lets keep it under $7,000 used, but interested to hear what used speakers rarely get listed for sale because they are so sought after and if they do appear they get snapped up very quickly?  Cheers

Kef R107-R107/2 sell quickly in my area when priced right. Revel f series also seldom come up.
I haven't heard much about these speakers in quite some time.

Acoustic 1+1s

Dahlquist DQ10s

Infinity 2000A's and Monitor 1A's. Great speakers from the early years of Arnie Nudell's company. The 2000A was a 3 way design using a 12 inch woofer, Peerless cone mid and 3 RTR electrostatic tweeters. The Monitor 1A was a 3 way in a taller narrower reflex cabinet using a 12 inch woofer, a Peerless dome mid and a Walsh tweeter (the size and shape of an ice cream cone!). Both models sound superb. I own both.
