Info on Klipsch Cornwall Loudspeaker System

Recommended Posts

Hello, my uncle passed away and i have inherited his old Klipsch speakers. I was wanting to get information on them such as what year they were made etc. I do not intend to sell them, but would be curious if anyone knows what they would be valued at. The serial numbers for both are 9P411 and 9P412. Thanks for all your help.

I am Not sure how to attach an image but the information on the back of the speaker is as follows:


“Cornwall Loudspeaker System

Type: C-WO

Serial: 9P411

Klipsch loudspeakers are protected by one or more of the following Patents:
