The ohms sold Direct only since mid nineties are versions 2 3 and now 4. Originals sold prior via stores were not as refined. Modern day ohm Walsh stack up well in all regards sound wise. Originals not as much. They are controlled wide dispersion not true omnis. Most info posted in last ten years is still relevant.
Ohms are not Bose and vice versa. That compare is not relevant.
I have very highly regarded kef meta speakers and two pair of modern ohm Walsh. The ohms are different obviously but compare favorably in terms of overall sound quality. What one prefers is always a matter of taste. Ohms do the very large sweet area thing uniquely well. Imaging is also unique but top notch. My opinion. See my system posted here “Sound Chaser” for reference. Happy to answer questions as best I can. Cheers.
