What vintage speaker might you use today

Dahlquist DQ-10s are still the price per dollar king IMHO. They may take some work due to their age, and a decent size tube amp, but then they really shine.

Hey Schubert- 
The Allison Threes were the ones made for corner placement.  I'm using Allison Ones, which are essentially two Threes together and these are meant to go against the wall but away from corners. 

I'm eager to join the modern world but i still love how these sound. 

I had my KLH 17s recapped and was shocked at how good they sounded. 

I have a pair of Advent Legacies from the 80s Jensen era. Definitely midfi, but non-fatiguing and very good bass. Somewhat veiled and polite, but ideal for used $1 classic rock Lps. Surprisingly, I put on some vintage "smoker" sax jazz and they sounded nice. Vocals are a bit flat. I'm going to refoam my orig Advents over Xmas.

None. I've owned and heard so many vintage speakers that I would not seek one to build an extreme system.
