Really nice looking, all rear panel labels, No cabinet dings just need TLC to look awesome. I’ve not done a thing to these. Grills look especially nice. Cabinet finishes DO match. Apparent color differences due to lighting. Tweeter pots will need to be cleaned. Both tweeters DO work. Grills have not been removed. Apparently quite well glued. As the speakers sound great and seem to be 100% original I’ve not forced it. Hope to hear from you. And you can test them when / if we meet. The item “AR-4x Acoustic Research Speakers.
