Thiel Cs 2.3 with neodium Tweeter of CS 2.4

Just sell your 2.3s and buy used 2.4s.  Not worth the headache of trying to get the 2.3s to sound right, and sadly the company’s no longer around to advise you.  I’d personally explore other brands as who knows how long parts will be available for Thiels.  Vandersteen, ProAc, Joseph Audio, Usher, all excellent imaging/Soundstage speakers on the level of Thiel IMHO and all still solvent.  

Thanks for sharing all that good info after the fact.  I’m out.  Good luck.
