Ohm Walsh Micro Talls: who's actually heard 'em?


Hi,

I'd love to hear the impressions of people who've actually spent some time with these speakers to share their sense of their plusses and minuses. Mapman here on Audiogon is a big fan, and has shared lots on them, but I'm wondering who else might be familiar with them.

Hey guys!
  Hope you don’t mind my jumping into this thread, (Infinite Jest got nothing on this thread). I began reading it a couple of weeks after my Ohm Walsh’s, (I believe they called them F-4049’s) arrived. They are refurb pyramid cabinets with new drivers, bought on sale.
  I wish I’d come across this thread earlier, as I had a number of misconceptions about these speakers, and might’ve chosen differently. Having never heard, or even seen them “in person”, I was concerned about bass reproduction. From the pictures, I thought the cans were much smaller than they are.
  As you all know, I needn’t have worried. But I was certain I would need Super Walsh’s, with their built-in subs, and of course the biggest driver I could afford. And when I first looked at the “beta” F-5015’s on their site, I thought, “Hey, I can almost afford these!” I was ready to pull the trigger. Then I noticed it was the “per speaker” price. Ugh, I hate when speaker companies do that! Who buys one speaker? Four grand was really my upper limit, and yes, I needed more than one speaker. Long story short, the sale came around, and I decided at the time that I would deal with non-existent problem of bass later.
  I have always purchased used equipment. You get more for your money and, as a working guy, that’s what I can afford. So I had no idea what to expect in terms of break-in. Out of the box, these speakers sounded terrible with most recordings. Very fat on the bottom, and recessed in the upper mids. They had a weird, hard to describe character, almost as if I was listening with a cardboard tube next to my ear. Yet, with certain types of recordings, mainly acoustic recordings, or sparsely-arranged amplified instruments, they sounded quite decent. They were very unforgiving of most multi-track rock recordings. To my ears, they had a very pronounced mid-bass, and I felt very much that I was hearing the cabinets. I was expecting a much more airy, non-cabinet/non-boxy sound.
  Into my fourth week, much of that seems to have worked itself out. Certainly the high end has opened up, and whether I’ve gotten used to the sound of the cabinets, or whether that has worked itself out too, I cannot say. It should be noted that I was used to folded-ribbon tweets, as I’d long been listening with ESS Heils. These were a modified/upgraded pair of AMT1-a’s which, aside from what the tweets did, made very transparent bass, (passive radiator design). Different in every way from the Ohm Walsh’s. As I say, these initial problems have worked themselves out, one way or the other. I do wonder though, whether I should’ve (could’ve) went with smaller, (and cheaper), drivers?
  This particular set of speakers comes with one three-position switch. It’s a low-end cut, although I don’t know exactly what it does. In the end, I settled on the bottom position, which provides the most trim, or whatever. I was having trouble frequencies in the mid-bass, or low-mids, and that bottom switch position seemed to tighten everything up. And it didn’t hurt bass response much at all. For instance, last night I pulled out Snoop Dogg’s classic “Doggy Style”, (now there’s an audiophile record, my friends!), and played the side with Gin and Juice. There’s a lot of very low-end synth bass throughout these cuts, and the Walsh’s conveyed that to my diaphragm very nicely. The highs are smooth and sweet, neither recessed nor harsh, with the sleigh bells sounding positively magical. I felt immersed in the music. Laid back, indeed!
  A big reason I bought these speakers was because I thought they would solve the problems of fussy seating and fussy speaker arrangement. As it turns out, more the former than the latter. I’m fairly limited in how far I can pull them away from the wall, and I have them about as far out as I can get without impeding traffic - 20” from the center of the cans. Nevertheless, this seems to work, again, as long as I use the bottom position of the switch.
  All in all, as these speakers open up, I’m becoming happier and happier with them. I have to admit, I was having second thoughts at first, but I knew I had to give them a chance to break in. So many people rave about these speakers, I thought, there must be something to them. As others have mentioned, I am now able to go to recordings that the Heils had problems with, and the Walsh's tame them. In fact, lately, I’m throwing all sorts of recordings at them - from Loretta Lynn, to Minor Threat, to Thelonious Monk, to the Feelies, to Led Zeppelin, to Stereolab, to Dr. Octagon - and they handle them all nicely.

Living-room = 20’ x 15’ x 8’ = 2400 sq. ft.
Speakers and seating are along the long walls.
Speakers are 10.5’ apart, and about 11’ to “sweet spot” (triangle). I sit off to the left of this spot, though.
They’re driven with a McIntosh MC352, off the 4 ohm taps.

sudont: Welcome to the thread and to the world of Ohm. I was very interested about your comments regarding the Hiel folded ribbon tweets vs. Ohm. I have yet to hear a folded ribbon tweeter that I didn't like. But, and this is key, the Walsh driver goes up to about 7kHz, where the super-tweeter rolls in (the Walsh driver rolls off by itself above 7kHz). So, a large portion of the treble is being reproduced by the Walsh driver.


As to the positioning issue, you are fortunate to have the switch, to reduce the bass reinforcment you get when placing any speaker too close to the walls. Also, at some point, you may wish to experiment with diffusion panels at the side and rear reflection points.


But please be patient. Unless you are playing them many hours each day, they will take several months to fully break in. Mine took close to six months. Also, while the speakers don’t insist you sit in a narrow sweet spot, I prefer to listen dead center for optimal soundstage presentation. YMMV, of course.


And don’t forget that John Strohbeen is always available if you have any questions or concerns. You can usually reach him on business days at the Ohm factory in Brooklyn. He’s a heck of a nice guy, and a very talented speaker designer/voicer.

sudont,


If you are finding the bass too much or not clean and articulate due to the larger driver size and if your floors are lively and have some give, like most modern suspended plywood floors found in upper levels of homes these days, consider placing the speakers on an isolation platform to clean up the bass and improve detail and clarity overall in conjunction.

I use Auralex Subdude platforms (about $60 each) under my smaller Walsh 2 cabinets. Subdude 2 platforms are 15" square. May or may not be big enough for your speakers. Very good at taming the bass nicely by eliminating interactions with acoustically lively floors. Most floors are that unless directly on foundation level of the house. If you jump up and down and feel the floor give at all or anything in the room moves or vibrates, you have lively floors that are probably best tamed with most any speaker that is delivering the bass it should.

Bondman,
Yes, the Heil tweeter begins at 850 Hz, and goes up to, well, I don't know exactly, but out of my hearing range. I imagine they rated them to 20k. Amazing upper-mids, crystal treble. But, perhaps because of that mid-range crossover point, the Heils did not have quite the lower-mids that the Ohms have. It's possible I'm not used to hearing that, and that's why the Ohms sounded a little fat down there.
As for bass, yes, that switch is a big help. Mapman, I read your discussion about the SubDudes. I, too, wonder if they'd work with these cabinets. This is the old pyramid cabinet, and it has a set of casters on the bottom. Do you guys have those on your speakers? My floor is a suspended design, carpeted plywood over two-by-fours, over a crawl space. My TT will pick up footfalls if I'm not careful.
It would be nice to find an affordable solution. If anyone has any suggestions, I'd love to hear them.

sudont:  I also thought I might have been hearing the cabinets "sing" in the lower mids.  The cabinets of my 2000s do vibrate.  But I think I was actually hearing the hollow body of instruments like acoustic guitars, cellos, etc.  I would bet that John Strohbeen was well aware that inexpensive cabinets will resonate, and works with that rather than drive up costs by trying to prevent it.  Also, with the drivers sitting proud of the cabinet, I don't think a lively cabinet is as much an issue as it would be with typical dynamic speakers mounted on a baffle in a cabinet.


As for the floor, please note that my 2000s sit on a custom pair of Sound Anchors cradle bases.  These solid, heavy bases have three-point adjustable spikes and enabled me to level the speakers very easily.  They sharpened up the imaging and transients noticeably.  I think they cost me about $350 shipped.  Worth every penny.  That said, I use them on a carpeted cement basement floor, so YMMV.
