Finnish National Broadcasting company had Yamaha NS1000M as their standard monitor.
This was a special version modified by Genelec. They removed the original crossover

This was called Genelec Triamp S45YA.

I have heard that 90 pairs were ever made.
It is unknown outside Finland.

I am chuffed that I am getting my hands on a well preserved pair this week.

Here is the front:

Will post better pictures later this week.
