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.

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.

I can't comment on the older models, but my Ohm 100s absolutely go towards the leaner, more articulate side through the bass region.  If anything, I'd call the bass ever-so-slightly over damped.  It's possible that a more recent model may better serve the OP's preferences.
