I have two pair of Acoustic Research AR-3a speakers. These speakers were inherited. They all need the woofer re-foamed. I do not know of the condition of the crossovers, capacitors, mid-range speakers or tweeters. However, these are some of the best speakers ever made, and worth of the effort to repair if needed. Included are a pair of nice acrylic speaker stands. Acoustic Research AR-3a Specifications.
