The speakers were pretty old even so the support at Klipsch had difficulty identifying them but what they determined was the model was similar to the CA-6T. They must of had some variations of custom outdoor speakers back in the day. The tweeters were fine but the woofers were cached. I found some replacements not for my model but took a chance on pictures that looked similar to my woofer and had to do some fine dremel shaving to make it fit but the results were amazing!
