With free shipping....great idea.....shipping would be a show stopper.

Agreed,  shipping charges and potential return delays would IMHO be a real deterrent.   I know I suffered (not really, but w/anticipation and anxiety) a WHOLE WEEK waiting for my upgraded B-2 recapped crossovers.   JMO,  but a very novel and creative idea.

Maybe at the local/regional level.

 There is no way I'd pay to have a pair of Klipsch speakers restored, then turn around and trust them to ANY cartage company. No way. That's one reason I personally have picked up about 95% of the Klipsch speakers in my possession. 

Plus it's fun to do it yourself. We do have upgrade kits available for drivers/networks for the H II, LS, Khorn, Klipsch Belle that upgrade those models to the very latest mechanicals.

You got out of that cheap with B-2's, I had B-3's in mine .............. Who's doing yours? Wait until you put them babies in, you think you had nice speakers before, sit down, strap yourself in, and let 'em rip Bud, you're in for a real treat, it will be like CHRISTMAS again !!!!!!! The neighbors are going to hate your butt .............. You just got a NEW pair of Cornwalls ....... Don't get evicted !!!!!!!!!!
