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.
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.
Polarin,
Agree with you about looks! OTOH, when you first get the speakers, the casters are convenient. Long-term though, they have to go. I like your solution. Spikes on heavy equipment can make it difficult to move around. I always imagine one of those spikes going right through my foot.
Mapman,
Thanks! Maybe Polarin's rubber feet on top of the SubDudes would work? Will the SubDudes support that kind of weight, though, even if they do fit?Here's another thing I wonder: Mapman, you have a couple of different Walsh drivers at home. How do they differ in terms of sound? Do the smaller ones do better at the high-mids? From what I've heard you guys say, they seem to do no worse at the low-end.
What about sound at lower power levels? Do the smaller drivers do better in this regard? I find I have to play mine fairly loud to open them up, although this also seems to be a diminishing problem.
Bondmanp,
I think the cabinets have to play a significant role. After all, it is a type of bass reflex design, with its port on the bottom. I'm really not clear at all about how the CLS driver differs from a conventional driver, e.g., how they get it to vibrate the cone, and behave less like a piston. But looking at the "bottom" of the driver, it looks very much like a conventional driver, with a diaphragm, magnet cover, and flexible surrounds. This is firing into the cabinet, so it has to produce resonance.
If I'm not mistaken, stuffing is used to control midrange within the cabinet. It would be interesting to know how much, and what kind of, stuffing is in there. A person who knew what he was doing might be able to make some adjustments there.
I feel fairly certain I'm hearing the cabs, or the room, (or both). But as I say, much of this odd sound seems to have worked itself out, and the bass cut switch has helped in this regard. I'll need to go back to critical listening to see where I'm really at. I'm not distracted by their sound anymore, and that's a good sign.
Martykl,
Thanks for your comments! I can't help wondering sometimes if I bit off more driver than my room can chew. It would be nice to compare a smaller version of the Talls, just to see, particularly for quieter listening levels. But again, the sound is improving, and perhaps all these problems will work themselves out as I exercise the speakers?
Mapman,
Let me just add: When I first talked to JS, I brought up low listening levels, and he said the bigger speakers are easier to drive, i.e., more efficient. Does that make sense? I’ve always thought you wanted small speakers for lower level SPLs, and because they have less mass, they should be easier to drive. Anyway, what’s your experience with the different Walsh’s?
Accurus,
Have you popped the top had a look in the cabs? I was reading up on stuffing and cabinet sound, and came a cross this article:

The Cabinet Face & Stuffing

They say that cotton, followed by fiberglass, are the best materials, and that neither are much used today for various reasons, not least of which is cost. Scroll down the page a bit to get to it.
Here is another internal "tweak" I came across. I should say, I haven't tried any of these, but you might find it interesting. Not sure what's inside the Ohms, as I haven't looked inside yet.
Mapman,
I sometimes miss the tone controls and loudness button on my old McIntosh. I worry about my ears as I get older, and a little bump in the treble and bass could be useful here. But just try to find a preamp with these today! It seems only McIntosh still includes them.
I'm sure you'll have no problem selling them. 
Where I'm at is, I decided that I don't like the way the speakers look with the grills on. They sound better without the grills as well. I've been looking around, trying to find some nicer-looking wing nuts to replace the ones on them, or similar type of fastener, and am wondering if anyone else has done something along those lines?
I have also been thinking, wouldn't it be cool if the cans rotated a little? Let us say, forty-five degrees from front/center? That way the cabinets could sit nice and straight, while you aimed the tweeters where you wanted. Of course, I have no idea what it would take to build them like that, but something about that round can makes me think of turning it. And, of course, it offends my OCD to toe the cabinets out, or in an uneven way.
