Buying notes
Acoustic Research three-way acoustic suspension. Foam surrounds on the woofer are almost certainly rotted; refoaming is standard maintenance, not a deal breaker. Budget $80-120 for woofer surrounds. Check tweeter and midrange output. Original AR drivers must be retained for correct character.
