The original OHM F from the 70's was omnidirectional.
Since the early 80's till current the Ohm Walsh series speakers, they have been quasi omnidirectional by that I mean the the sound propagating from the rear of the speaker is around 20 db less then what is radiating from the front.
Ironically there hasn't been a lot of changes from my 1984 Ohm Walsh 4's to today's Ohm Walsh TallĀ 3000.
I'll give you some specs that are not on the Ohm website; maybe even the German distributor may not be aware of them.
Mapman will correct me if I'm wrong.
Common specs between Ohm Walsh 4 and Walsh 3000
Weight: 63 lbs. per speaker
10" downward facing time aligned driver
1" soft dome super tweeter angled inwardly at 45 degrees from front of cabinet (ferro-fluid cooled)
Crossover: 1st order Butterworth @ 8K Hz (6 db per octave)
Sub Bass Activator kicks in at 60 Hz to manage bass response
Impedance: 6 ohms
NOTE: there is no crossover(s) till you reach 8,000 Hz
That's one of the reasons the sound is so coherent.
They sound more like an electrostatic speaker than a box speaker but unlike most electrostatics these have some serious bass
