Best 40 to 50k used speakers

@jderson No point really with your comment.

An (in the room) amplitude and time corrected ATC 150 asl is very hard to beat.

The ATC 15 inch woofer produces some magic that is hard to change for anything else. I’ve tried and am trying :-) Then you have the transparent mids. Maybe the highs could be bettered but that's not so important for me. And the possibility to play at thundering levels...

@thieliste I have the passive model 12 and 19 and the active 150 asl. I also have the Thiel 1.7, 2.2, 3.6, Ultima studio 2 and D& D 8c among others. Nothing I'm afraid really in my ears compares to the active 150. Might be because I listen from the bottom and up. Also sometimes at high spl's. So a very clearly defined bass/low mid is very important for me. And the 150 with the 15" woofer gives me that. Can't really say anything about passive 50's and 100's. Though I know the 110 is popular in studios. However, this is important, without digital amplitude and time correction it wouldn't be fun at all in my not too big room. I run Roon with (Acourate) convolution filters to a Matrix dac/pre.

@thieliste Well you soon get used to the size...in my eyes they're beautiful. You just have to spend some dollars on appropriate jewels to the wife :-)
