⚠️READ AD! Vintage 1970s USI SP-7 3-Way Air Speakers

70’s pair of vintage USI (United States Industries / Consolidated Merchandising Co.) Model SP-7 3-way air suspension speakers. ⚠️2 tweeters are currently NOT working anymore on one speaker, probably due to a loose terminal connection in the back. (Easy project for an audio technician or enthusiast.) Lost interest and I need the space. Pickup only in Burlington. (Pinedale Ave)
