Pair of vintage 3-way speakers. (1) 1/4" clear poly dome tweeter (better version). (2) 6" woofers surround, vented dust cap treated cone. All drivers sweep tested OK. Audio Pro REV 3 mod. Basic crossover update. Also treated all driver butyl surrounds. Big speaker, big full sound, clear voice. 9/10 condition, vinyl walnut cabinets, black knit grills 7+/10 condition have frayed obviously on side edges. Overall better version parts in these SDA's.
