I've never heard Ohm Fs.
I a/b compared the new Series 3 100 drivers versus original Walsh 2 drivers from the early 80's before I purchased the larger f-5s with the Walsh 5 series 3 drivers.
The original Walsh 2 drivers had significant and very noticeable sonic shortcomings when compared the the new Series 3 Walsh 100 drivers or even my "modern" Dynaudio or Triangle (with subwoofer) monitors.
Though inferior, I still enjoyed the original vintage Walsh 2s for many years still, mainly due to the characteristics of the Walsh sound.
