Anyone dislike Ohm Walsh speakers?

I would counsel against buying any speaker without listening to it first. From what you’ve said, you’re potential purchase is on the basis of reviews that you have read. Your ears and taste may differ substantially from the reviewers. I’ve read many great reviews of speakers and then listened to the actual speaker. While appreciating what the reviewer heard and raved about I’ve still walked away and said to myself “good speaker, just not for me”. One person’s “detailed” is another person’s “cold and harsh”. Another’s “warm” some would consider “muddied”. Beauty is in the ear of the beholder. It may turn out that you absolutely love the Ohm Walsh speaker when and if you actually purchase it. But I wouldn’t bet on it.

Not the answer you are looking for, but IMO, if you are looking for an endgame speaker, of which I've had several :) you should buy something you can audition in your home country.  Everything else is a guess, no matter how well-reviewed.  Auditioning before buying used to be the norm.  Now it seems to be the exception and I personally don't think buying blind is the best way to build a system.  At least that's what I think. 

Agree with the prior posts to try them in your room with your equipment.  However here’s my experience with Ohms. 
I briefly heard the F’s in the 70s and was impressed. Hadn’t thought much about it until recently when I heard Ohm was still around. 
I picked up a nice used pair of the 4’s and they sounded great - very natural and easy to listen to. They weren’t as detailed or extended on top like some newer speakers, but the coherence and openness made up for a lot. 
I took a chance and ordered the upgrade to current tech which makes them equivalent to the 3000 talls. I’m very happy with the upgrade and the upper and lower ends are more extended. 
I end up listening to them more than my other Salk Songtower / AVA system but like both a lot. 
Maybe the safe thing is to see if there are any used pairs in your area. 

I have a dedicated music room that has been hard to get right and have tried to audition omni directional speakers. COVID has not helped and no dealer in Adelaide has anything omni directional.  The Ohm Walsh has been top of that list.  However I now have installed bass traps, one is 1.5 x 0.5 x 0.5 metres and 2 subwoofers? and have stopped thinking of new speakers just enjoying my Audio Physic Sitara 25's. I did own a pair of Sonar OA14's with 4 tweeters per speaker but actually much preferred by Royd Doublets which I owned at the time and for nearly 20 years.

I have owned a pair of Ohm Walsh 2000s for a little over 2 years now, and I can say that I am completely satisfied with them. Indeed, I think they are the best speakers I have ever owned, with the exception of a Pair of Ohm A speakers I owned back in the mid-70s. I also owned a pair of Ohm F’s during that same period, and I would say that the 2000s I currently own are better than the Fs, offering better imaging and better bass.
One important improvement in the original design worth commenting on is the decision to dampen the higher frequencies (above 5K) from the rear of the speaker to the front wall, and to replace those frequencies with a super-tweeter in the front crossed in at 8K.

This corrects the generally poor imaging that plagues omnidirectional loudspeakers and also allows them to be placed much closer to the front wall. As a matter of fact, the new Ohm Walsh line are all designed to be placed anywhere from 12” to 24” from the wall, to be determined by careful listening. Mine are exactly 13” from the front wall and provide excellent imaging with a terrific sound stage. The overall sound I would describe as coherent and natural. They have the clarity of a good electrostatic speaker but with terrific bass (deep, tight and detailed) and the magical sound stage that only an omni can give you. And yes, the 2000 is still an omni in spite of the design mod described above. The only thing affected is the high treble (above 5K). All other frequencies are generated omnidirectionally by the Walsh driver, so the speaker definitely sounds like an omni, only with focused imaging.
The 2000s also are capable of playing majestically loud, given enough power. I am driving them with 160 watts RMS per channel into their 6 ohm load, and they love it! One caveat to consider though is they are extremely revealing. If there is anything wrong with your electronics, there will be no hiding it. In that respect, the Walsh driver is much more like an electrostatic than a conventional speaker.
