Update : Please note since the last time I shot the video, I cleaned the pots by using dremel tool and deoxit spray. Now the pots are smooth. I will shoot a new video shortly. SCROLL DOWN FOR MORE Pics and Videos. Acoustic Research AR3-a Speakers. I tested each driver and all of them work well. I also shot a video to show you that. Vintage Speakers stored inside and are in respectable shape for speakers that are 40+ years old! The cases are in good shape. I know many people will want to restore these speakers, so I have not attempted to alter them in any way. The grills are new. Very good quality, durable, linen cloth (off-white). Please ask any questions you like and I’ll do my best to answer! Can be checked out and picked up in NYC (Price would be cheaper this way). I can also do trades.
