SOLD! Epic Series K-64-KN / K-63-KN Driver

Recommended Posts

I collected a few of these a while back to play with... never ended up using any them...

 

They were all labeled K-64-KN so they were originally used/meant to be used in the CF-2 with a K703 horn. You likely already know but in case you don't, this is the exact same driver used in the K-63-KN (CF-3 and CF-4) it was just mated to a K603 horn in that assembly. Speaking of used/meant to be used... I am not fully aware of this guys past life/lives. I know what little I did with it and that the driver still test good but can't say with any certainty how new or used it actually is... just trying to be honest. Driver is dated Nov 4 1995

 

I have this currently listed on ebay for $130 shipped within the continental US (I would prefer not to ship internationally)

 

Side note: I actually have a CF-2 crossover lying around in the garage somewhere if some one might be interested in that too... no horn though

 

Edit: All of these have been sold off as of Feb 2018

My CF-3's use the K-63-KN.  Is it said somewhere that they are the exact same driver?  Maybe @Chief bonehead could let us know exactly.

I don't have pics handy but my k-63s had a big K-63 sticker on them. It would be interesting to know the technical differences between the two.

K-63-KN and K-64-KN are the assembly numbers for the horn and driver combinations. Similar to the K-53-Ti being the assembly number for a K-52-Ti driver and a K701 horn...

 

older examples would be:

K-53-K = K-52 & K701

K-57-K = K-52 & K601

 

Much of the readily available information on these assemblies was lost when Klipsch deleted the old spec pages from their website.

From a manufacturing standpoint it would make little cost sense for the driver of these 2 assemblies to be different... not that it couldn't happen, there would just have to be a good justification for it like the potential benefits of using a different diaphragm material or impedance (4 vs 8 vs 16 ohm). In this situation though the drive of the 63 and 64 are both 8 ohm nominally and both utilize a rather special/proprietary aluminum diaphragm.

Another fun fact (opinion):

 

This driver appears to be (rather obviously) based on the Electro Voice DH1506 / DH2 family of design... in fact you can swap the snouts (compression chamber/diaphragm) and magnet assemblies of this driver and the K-60-M/DH1506 (I did once for fun). My guess is that they rather liked the EV driver (obviously used it for the K-60-M) but needed it to be significantly lighter for the CF series applications.

Just as a heads up, I think I'm going to put these on ebay this weekend...

Are these still for sale?

 

 

I apologize for the (very) late reply... I do not get on this site a whole lot and only get sporadic/inconsistent email notifications from it...

 

Yes, these are still for sale
