Now it's possible to restore the 3/3as to nearly new specs. Two gents are rebuilding mid and tweeter drivers once thought as paper weights when they were fried, or barely producing sound.
I've restored both AR models, and had the tweeters and mids rebuilt by these gents.
Both are outstanding when properly restored. I have a decent speaker collection, and my 3's are right there with all of them. Most are setup in my basement/cave. The 3's are in my family room 18 X 22 with 12 foot vaulted ceilings. They have no problem filling the room with sound. They look great and sound great. A few weeks ago, a neighbor was over for a demo and was extremely impressed. He has a set of Dynaudios, forgot the model, he thought the 3's sounded better! I have to say, this was a surprising comment.
The 3/3a sound is dimensional, wide sound stage, the highs are delicate and clear. Bass is deep, smooth, punchy, what they are known for. The 3a to my ears is more forward in the mids. The 3, has a more natural sound presentation, great balance.
Are there better sounding speakers, sure, but these are historic, iconic, industry standard setting speakers.
Every audio enthusiast should hear the 3/3a, driven by a good high power amp.
