Klipsch speaker choices

I looked back through my notes from Bob Crites and son. I asked about the "B" and "D" version. He said the B goes higher than D because of the CT120 tweeter. And most people buy the B. I am not sure if it is because he steers them that way or not?
This all started with me looking at going from RF3’s to Heresy. then when I figured out I would have as much or more money into rebuilding or purchasing a set of Heresy.
I have looked around for opinions about bracing and batting these cabinets but since I am not a speaker designer or wood worker, I better be careful.  According to Crites these two changes make no differences in the measurements.

I have heard the new Cornwall and it is the first version I have liked. The boomy box sound on the first three versions is gone and lined up in Hope for us to hear were the latest Heresy, Forte, Cornwall and La Scala. Of the four the La Scala showed the least improvement and the Cornwall the most. Until now my favorite Heritage type speaker were the Chorus speakers but no more. Now value for money spent I would any day seek out an old Chorus and recap the crossovers and stick a set of MAHL V2 tweeters in there and have awesome sound for much less than new Cornwalls. If the 6G was not a problem and I was not handy with speaker work you cant go wrong with the new Cornwall.

  Let me rephrase the I have liked comment. The new Cornwalls were jaw dropping better than any of the others and an amazing step up.
  One thing not mentioned much is the pro Klipsch gear out there. The KP-301 IF you can find any are the pro versions of the Chorus speakers and these respond really well to recaps and tweeter upgrades plus the crossover is different and these are 200 watt rated where the Chorus are 100 watt rated and both have the same 101db efficiency. If you get really lucky and have the space and WAF does not matter there are KPT-456's out there sometimes and KPT-904's. These often sell for $1,500 or there about and you will have entered a whole new world of audio quality.
 

does anybody have a link or source to a horn that would work suitably to get the Klipsch majik on a 2 way homebuilt speaker? Nothing super expensive... extra points if I can find it in south america....

Canibefrank I would start with Crites speakers.  They have plans for a 2 way Heresy ported and the Cornscala 2 way.   They will cut out the pieces and send them to you or assemble them.   They sell any and all drivers with cross overs to match.   There is also a PI speaker that is similar but I know less about them.   Also a diyspeakers website/forum.  Everything from single drivers to everything in between.

daledeee1, did you receive your Cornscalas?  If so, I would love to hear what you think of them.
