Current version of Roy Johnson's Time-Coherent monitors, latest crossover version, about 2 years old. I have two pairs of these - the second was going to be for another system, which never materialized. That pair, still boxed, is what you will be getting - serial numbers 8135 and 8136. I did not want to unbox them so I took photos of the pair I am keeping. The ones you get will have grilles over the woofers, I took mine off. Next to Quad 57's, these are the most neutral revealing time-aligned speakers you can buy, and they are dynamic and efficient. Tube amps love them. I use them with a REL B2 sub below 45 Hz.
