Just to be clear there are 5 generations of Ohm “Walsh” speakers
Original ohm F and A
1st gen Ohm “Walsh” line ie walsh 2, 4, 5
These first two versions were sold in stores onto the early 90s I believe
2nd gen Ohm Walsh X00 models and ohm 5 series 2
3rd gen series 3 (I have these)
4th gen x000 series which is current
ohm moved to direct sales only in mid 90s for these last three
