These are dated 1969. They have had the works done to them, cabinets completely sanded, small dings repaired and finished with Danish walnut oil. The crossovers were rebuilt with audio grade film capacitors. All 4 potentiometers were replaced with quality L Pads and the mid pots have had an audio grade 1% resistor added to replicate the original pots. The original pots have all been reworked and are included with the speakers. The woofers have been re-foamed, the grills have been recovered with a material that is very close to the original material. The brass AR name plates have been buffed to a beautiful shine and look like new. These have been playing in my shop for a week or so and they sound amazing. Deep smooth bass with very detailed mids and highs. Thank you for looking!
