Hese are my babies. I love these damn speakers but it’s time to sell them. Theae are Acoustic Research Ar4x series. My pair has a few nicks and such just see the pics. My pairs tweeters also arent original as you can see. I just put these generic tweeters in there for use. I do have the originsl tweeters and hardware but the tweeters are blown. One of the 6 inch woofers has a crack as seen in the photo. Other than this for some reason they do still sound good. My Tweeter potentiometers dont really work. I first cleaned them then they worked but only in the middle position. Turning them left or right and they won’t work. I hope they go to a good home. I had plans to order new POTs and new tweeters but I have too many speakers as it is lol. The item “Acoustic Research Ar4x Speakers Vintage” is in sale since Sunday, October 02, 2016.
