[Help identifying what I have here]

Preface:  Complete novice

 

I am working on identifying what I have here.  I have deduced that they are a pair of klipschorn (aka: corner horns?).  There is a "Tested & Approved by Klipsch & Associates" sticker dated either April 23, 1951 (or 1961, but I'm fairly certain -- 1951) on the crossover (not sure if that is the accurate term).  

There is also a letterpress in the wood, on the panel supporting the crossover, of "1056".

 

Not sure where my family member got them -- so flying blind here.

 

Any help would be much appreciated!

 

Also -- any help ID'ing the amp & power amp (or where I could find out more about them) would be great as well.

 

Thank you in advance!
