There are many directions to go with crossovers.  One decision to make is replace or rebuild.  Crites Speakers can rebuild old and crusty XOs, bringing them back to factory specs.  Here is some info and pricing, look under the phrase in caps 'Rebuild Your Crossovers'.  I think they also sell rebuild kits that are cheaper, with you then at the helm doing the work.  I'm not that savvy with electronics, so I sent my Forte II crossovers to them.  They also sell new XO's, here.  There are a few different kinds that were/are used in the Klipschorn, and everyone has their preference.  Crites makes this one that seems popular on this Forum (I've read about it often).  OK, this has been a HUGE ad for Crites.  

There are other makers of XOs too.  Others here will hopefully give more specific info.

It seems to be prudent to take Khorn mods step by step to get the best results, so I recommend you get a recap kit from Bob Crites and rebuild them.  (Bob can do the whole job for you if you want.)   Most likely that will be all you need.

 I would recommend you really looking onto Al K's networks.......they're worth every penny.

 Which crossovers are in your Khorns?

You will be amazed at the difference a refreshed network will have. And then again if you decide to go with one of the more exotic alternatives. ALK and Crites have been mentioned so Ill add Dean Westcott to the list. 

On my belles I have ended up with custom networks by Dean using vcap capacitors and have to say it is a remarkable improvement versus stock - at least to my ears!

A few things to consider when you decide to recap your Klipschorns, based on my experience only....

I bought the Crites do it yourself recap kit which was the most affordable high quality alternative (in my opinion).  I had a friend perform the actual install as I am not confident in my ability to do this properly and didnt want to learn on Klipschorns...maybe next time on something a little less important!

At first I HATED the way they sounded! they were MUCH brighter and my ears were used to the way they sounded before...I thought I had ruined my speakers!  I read about "break in period" and some people say they need to burn in, but an e mail to Bob Crites informed me of no such thing.  He stated that the values need to stay constant and any degradation from use would be a bad thing.  My ears were what needed the "break in time" and after a while I grew accustomed to the new sound and now I love the speakers again!

Now, here is the thing about the recap....

To do the upgrade with the kit, you cut out the old parts and wire in the new.  If I could have done it over I think I would have bought new crossovers and swapped the whole thing out, that way if I wanted to "go back" I could just swap the whole thing over again. (trying to reinstall the old caps after they had been cut out of the crossovers was not a viable option) but of course that costs more.  Also the intact crossover retains a value if you eventualy decided to "dispose" of it.

I have read nothing but great reviews about ALK crossovers and I am sure they are fabulous, but you pay for that quality, it is much more than the basic "recap". 

Just my 2 cents....

 Ed,

My plan is to purchase ALK XOs and replace the OEM XO altogether. 

My "Other" plans"

-I also plan I finding a good price on an MC275 to match.

-The Klipschorns sound so much better than my LaScalas that I cannot tolerate the Lascala as a center channel , Left surround & right Surround.  We are always watching TV/Movies in Stereo with the Klipschorns and JL Audio Subwoofers.  I'm going to give the inwall option for HomeTheater & the Klipschorn & MC275 for the Vinyl/2 Channel experience.This way we save on space yet acheive high fidelity. (Our two bigest factors -space, fidelity) I could go on and on about how well Klipschorns use the space in your listening room.  For a ~52" X 31 "HULK" of a speaker it hides very well in the corner- better than any floor stander.

That may be an oxymoron. Probably the most in-demand amp out there. On the positive side, they will hold their value.

There are too many *** crossovers. We need a consensus on the best three or four and dump everything else.

How about EV DC-One, Ashly Protea 3.24CL, and Yamaha SP2060?

P.S. A thread to setup your Khorns using the Yamaha SP2060: http://forums.klipsch.com/forums/p/156476/1653663.aspx

Yuck. :)

Us old folk like it nice and simple. Less is more.

Dean, I always knew you were a Luddite...

Oh yes, absolutely. :)

I think an extra two words were put in...... "in time"  I think your ears needed time to break...
