I do Buzz, they were a knock-offs from the famous Speakerlab 7WA last great speakers that Speakerlab built. Much rarer then the 7WA as they were for the Canadian market. They like the Speakerlab 7-series needs LOTS of Power to make them sing, (old watts 125 RMS min.) per channel. like mine "Speakelab-7WA." (Cira) 1976-81, mine are from 1979. First these ??
