K-1013-K woofers for replacement for k-1036-k KLF-20?

[achapman]

Edit: Does this belong in the technical/ restoration sub? If so, can a mod please move it to the correct one?  

 

I purchased four of the K-1013 woofers from Klipsch closeout new old stock about 13 years ago and they've just been sitting. I also have two Klipsch k-22-k woofers sitting around unsure what to do with. Would the K-1013 work better than the copy woofers found on eBay from Midwest Speakers, MW-5010-8. I'm considering building a copy of the KLF-20 horizontal for a center. Currently I have KLF-30's for fronts, KLF-C7 center, KLF-20's rear, and KSP-S6 for surround rears.
