What used speakers raraely come up for sale

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.

Infinity Renaissance 90

Since I've been on the hunt awhile, I'll say Shahinian Obelisks west of New Jersey, or Hawks west of London.
