Review: Ohm Acoustics Walsh 5 Series 3 Speaker


Category: Speakers

Bottom line: Yes, I think these are world class speakers that are relatively affordable, that work well with good or even great electonics, without spending a fortune, and despite the modest price, and pre-requisites in term of the supporting system, can compete with the best at most any price.

About 1 year ago, after several years of living more or less happily with my then current system, I got the urge to investigate whether my system could be improved to my ideal. Like most, I am not in a position to throw tens of thousands of dollars into my system. A few grand max is the most I could rationalize spending to achieve my ideal.

I have had the opportunity to audition many systems and components over the years, and run different speaker systems in 6 different rooms of my house.

When the urge to explore upgrades came, I had a pair of B&W P6 floor standers in one room, a pair of Magneplanar MG1.Cs in another, a pair of Triangle Titus monitors paired to an M&K v1-B sub in another (for A/V), and a pair of original Ohm Walsh 2s in yet another.

Each of these speakers had different strengths and weaknesses.

The B&Ws were beautiful, had good bass and a nice warm sound, but I could never get the transparency, imaging and detail I heard with my Maggies or good electrostatics when I heard them, like the Quads.

The Maggies were attractive looking, had the transparency, imaging and soundstage, but were lacking somewhat in the bass and hard to place optimally without being obtrusive and lacking in WAF accordingly.

The Triangle/sub combo was very smooth detailed and transparent wit good low end good, very fulfilling, but perhaps a bit lacking in soundstage and the "live like being there" soundstage factor, which the Ohm Walsh 2's owned.

The older Ohm Walsh 2's had the most lifelike soundstage and imaging but the detail and balanced timbre was not there compared to more modern designs.

I realized at this point that the unique "live like being there" factor of the Ohm's were the most distinctive feature of all and would be the hardest and most expensive to achieve with other lines.

So how to get all the best aspects of all this into 1 affordable package?

The solution, at least based on reading, appeared to be current line of Ohm Walsh (Series 3) speakers. From what I read and heard, these retained the unique live performance characteristics of the older Ohm Walsh drivers + 20 plus years of refinement by Ohm in timber, balance, soundstage and detail.

Ohms current line of Walsh speakers are designed to provide similar levels of performance from small rooms to large.

So if your room is relatively small, in theory you could get no compromise sound with the smaller Walsh speakers that start at about $1000. THese would be the Micro Walsh models that received a sixmoons Blue Moon award (http://6moons.com/audioreviews/walsh/micro.html).

For larger rooms, the larger Walsh 300s Series 3 at about $5000 is the solution. The Walsh 5 Series 3 at $5000-$6000 dollars provides level adjustments that enable these to go in any room, small to large, and adjust the drivers to the room acoustics as the user sees fit.

So after some further lower cost experimentation with high quality monitors and the smaller Ohm Series 3 speakers in one of my smaller rooms, I determined that the Walsh 5 Series 3 drivers were the solution for me. But the $5000 and up cost was prohibitive. The solution: John Strohbeen at Ohm offered up a pair of refurbished F-5 Series 3 speakers with new Walsh 5 Series 3 drivers for lower cost. These went straight into my largest room which is about 30'X18' but L shaped, not rectangular.

Getting the high end sound I was looking for in the L shaped family room was a unique challenge. An advantage of the Ohm Walsh CLS drivers (particularly the adjustable Walsh 5 drivers) however is that they are fairly easy to place and still get excellent results.

The F-5s replaced the Magneplanars in the big L shaped room. I loved the Maggie sound but these were very hard to place for optimal sound.

The Ohm F-5's have all the great qualities of the Maggies, but are even better and provide better impact and dynamics, particularly in the low end.

So what do the F-5s sound like?

Well, without, trying to be coy, I'd say they sound like whatever source signal you happen to put through them should sound like in your particular room. I honestly cannot fault them in any way I can think of. Maybe they do not have the nth degree of detail of a good pair of monitors perhaps. But if so, it really doesn't matter because when you listen, you do not get the sense that you are missing anything.

What the Ohms do perhaps better than any other speaker design I've heard is transform your room into a concert hall. If you think about what more can you ask from a pair of speakers than to provide the best sonic rendition possible in your particular room? Take any recording on any system or any live performing group or ensemble and put them in different rooms or concert halls to perform, and they will sound different in each room everytime. There is no ideal concert hall just like there is no ideal speaker or system. Each is different. Furthermore, you will hear something different in even a great venue depending on where you sit. So location in the room relative to the performers is a factor as well.

The F-5s sit about 4 feet apart and about 3 feet from the rear wall. The rear wall is about 20 feet wide. The Ohm CLS drivers seem to work like what I would call sound projectors.

Much like a video projector projects a picture onto a wall, the omndirectional Ohms project the sound in all directions, upward and 360 degrees around, similar to how the sound eminating from a live act is projected in all directions, reflect off the walls and other solid surfaces, and eventually reach your ears.

As I indicated earlier, what reaches your ears with the Walsh 5 Series 3 drivers is for all practical purposes whatever the music signal input was.

In my case the soundstage extends fully from left to right wall, about 20 feet, even though the speakers are only 4 feet apart. Despite the fact that my speakers location is skewed about 3 feet to the right of center, mono signals occur exactly at the mid point between the walls and extend to the walls fully both left and right. The soundstage extends well back behind the rear wall as well.

Individual instruments and recording mix elements are crystal clear and balanced from top to bottom and can be picked out easily due to the huge soundstage.

Furthermore, the soundstage and overall clarity of presentation holds up no matter where you sit in the room. Like sitting in different seats in a concert hall, you will get a different somic perspective in each location, but the presentation is full, complete and yes coherent regardless (hence the Coherent moniker in the driver name?).

The Walsh 5 driver are only 87db efficient, however my 150 w/channel Musical FIdelity A3CR has no problem driving them to realistic listening levels. I've found both the Walsh 5 series 3 drivers in the F5s and the smaller 100 drivers in the super Walsh 2's can take whatever power you thow at them and deliver the goods.

My only wonder with the F-5s is what they might be capable of if I threw a top notch high current monster amp at them. This may be the next frontier for me to explore someday.

See my sonic comments on the Walsh 5 Series 3/4 in a more recent thread, "Ohm Walsh 5 S3."

Mamboni had reviewed the Walsh 5 S-3 in Audio Review before I purchased mine. I have never been able to approach the measured flatness of response he gets in his room. There is a strong peak in my room in what I label the lower midrange, between 150 and 300 Hz, seemingly a floor-to-ceiling mode resonance since it doesn't vary much with room placement. In another room with a drop ceiling and insulation above that, this peak is not really apparent unless you are listening for it.

I think that the Walsh speakers work better than most modern speakers with a wall close behind them. John Strohbeen told me he designs them for placement about two feet from the wall behind them. As Mapman says, in such a position they act like a video or sound projector onto the wall behind them, but there still is excellent depth of field, unlike most speakers so used. In my main audio room, I oscillated between having them set up firing into the long dimension of the room with eight feet behind them to the wall, and firing into the short dimension with the long wall only three feet or so behind them. The bass response was far flatter but not quite so extended the latter way.

Bass response is quite extended. In my room response is only 4 dB down at 20 Hz with the speakers firing across the short dimension. Firing into the long dimension, response does not fall below the 1 kHz level unti 16 Hz. Yes, the JL Audio subs add yet-further extension (flat to 10 Hz) and punch, but for the size and price the Walsh's bass extension is uncanny and unmatched in my experience.

The debate over whether the Ohm CLS driver is a real Walsh driver is pointless. No original Walsh driver could play as loud or cleanly as these could with any amount of power behind them. You needed 200 watts to drive them to moderately loud levels and less than 300 to break them. And beginning with the Series 3 CLS drivers, the amount of power needed for high SPL and great dynamics decreased greatly. With my Series 4 prototypes, driving them loud and clean is now child's play, well within the capabilities of a modest home theater receiver.

As to coherence, the Walsh S3 and S4 drivers sound like a one-way speaker. The single capacitor crossover to the tweeter at 8 kHz is not audible. Period. They are like Quad electrostats in this respect and far better than Magnepans. Only a very few other speakers I've heard can be listened to in the near field (as I often listen) without hearing out the individual drivers.

Calling the driver a "line source" IS a stretch in terms of the driver dimensions. However, if you listen from back as far as the speakers are apart, the name makes sense. The apparent sound source expands vertically to fill the floor to ceiling distance, despite the fact that the actual driver is less than a foot tall. You have to hear this for yourself to believe it. And if you listen in the near field with the speakers far apart, as long as you listen at the correct height (ears just below the top of the driver can) they sound like pulsating sphere point sources, disappearing into a very coherent, open soundstage.

My only sonic caveats about the Ohm Walsh speakers relate to what I mentioned in the other thread. They share, with all other wide dispersion speakers, the quality of imposing more of your listening room's acoustics on what you hear than narrower dispersion speakers do. Whether that is bad or good, you have to judge for yourself. Many find such designs sonically very attractive since they make all music sound big and very open. Combine this with the very canny tonal balance Ohm has chosen and the other qualities of the CLS driver and you get a mighty attractive total package of coherence, generous warmth, space, relaxed openness, size of presentation, and extended highs and lows which I've labeled the audio equivalent of comfortable old shoes.

No, they are not the last word in nuanced detail either spatially or in terms of what is usually labeled "transparency," but they are not slouches in these areas. No, the cosmetics of the driver can are not the best, but the grills look very nice and will cover that if the look of the cans bothers you. The binding posts did not take kindly to ProGold, so I replaced them. The driver cans form a death grip with the cabinet once screwed down and are very difficult to remove when necessary, as when one of my CLS drivers developed a case of high distortion and needed replacing. I do not find the switches useful, but then I have a TacT RCS 2.2XP to handle frequency tailoring; users with such tonal control could save $1,000 and buy the 300 without the switches. Nothing men make is perfect. The particular set of compromises Ohm has chosen here will please most users a lot, I think.
I think your review is spot on. I've had my Walsh 5 Series 3 for about 4 years now and I just love them. I listen to them every night after work and every weekend. They just produce beautiful non-fatiguing music, great imaging and a tactile acoustic - they disappear in my room. As I write this I am listening to Hurford performing Bach organ works - the huge expansive sound, reverberent field and bottomless yet taut bass is astounding. The Walsh's are totally coherent and clean from subway train rumble bass all the way to evervescent cymbal partials.

My greatest fear now is mechanical failure of my Walshes; I've got my system finally sounding perfect and do not want to change a single component - most especially the loudspeakers!

How did you get the Walsh head units off the cabinets? Mine are stuck on tight as well. I suppose I'll just play the hell out of them until they wear out in 20 or 30 years!
I wanted to share some tips based on some recent experience.

The Ohms are fairly easy to locate compared to most designs, however I have found that optimal placement achieved via critical listening and experimentation with location is critical to achieving the true "magical" results that many who have heard Ohm Walsh designs associate with the brand from experience over the years.

When properly located, imaging accuracy in the horizontal plane should be razor sharp and well defined and extend significantly from floor to ceiling, not fuzzy or blurry as may have been inherently more so the case with the original Walsh CLS design from the 80's.

Also, once fully broken in the bass foundation in good recordings should be rock solid and have a lot of impact and dynamics, not sound soft or mushy or diffuse.

The original Walsh CLS line from the 80s is by far the most commonly found. The recent Series 3 line (~2005-present) is a major improvement. If you've heard original Ohm CLS speakers from the 80s and liked them but had some reservations, the new Series 3 line is definitely worth a try.

Interconnects can also make a difference with the Ohms. I have noticed major differences in micro and macro dynamics from IC to IC.

DNM Reson interconnects work very well with the Ohms in my system.

Speaker cables may make a difference as well but I do not have much uselful info to offer up on that topic.
