What speakers have you mistakenly let go and then later repurchased?

I have a pair of Spendor SP9/1's that I'm afraid to let go of for this reason - they don't do anything seriously wrong.  I've owned them for over twenty years.

That's a speaker marriage. 😁

JBL 4365. Alas.

I had a pair of modded Dahlquist DQ-10’s That I wish I still had. The tweeters were replaced with a Decca ribbon tweeters and the crossover was updated with better components and the crossover point and roll in slope were changed.

Bought Paradigm Signature S4 twice. They do some things real well. 
 

Others I would consider buying again Tekton DI (although I would likely do Moabs or higher) or Guru QM2 for a smaller 2nd system , or Snell type E lll as they were musical as all get out. For the prices you can sometimes find the Snells for I would consider them being in a garage system (although they deserve better😃)

JBL 4311. 

C.S.I., the soffit or bridge mounts with 2 6" woofers
