That was their official stance. I know. I had to deal with that nonsense.
Revel, B&W, and just about all manufacturers have sold single speakers. There is not a tolerance problem with them. Why would the KEF Reference line, which measures better than all of them, have a tolerance problem?
The KEF 201/2 is like +/-1.0dB FR and smooth off-axis. Why would anyone worry about tight tolerance? Makes no sense to me.
Every single speaker should have tight tolerance to the "master copy''. Every speaker should measure like the master "key". Then they will all measure like each other.
