A friend of mine sent me an email yesterday telling me he picked up 4 Sp 3700 at an estate sale in Maryland. I can find much helpful info on these speakers. Any info would be appreciated. All four have sequential serial numbers and are in mint condition. From the pictures, the cabinets are perfect, all badges are intack. My friend says they sound great. Tks, Ron.
