Theyre unmarked, no model info except for the word 'eminence' across the dust cap cover on the front. They're coming out of an old pro reverb, so the pair in parallel can handle 40 watts. Thats the extent of what I know, because they were in the amp when I got it, so they're at least 10 years old. They're fine sounding speakers. The boxes are pretty stylin too. Email is better if you want to know more. I'm in the middle of moving and not checking in here all that often...
