Ohm Acoustics Walsh F-5015 speakers

Spacer

I have no doubt that the Walsh 5000 generation of Ohm speakers is a stellar performer. It's just that as an Ohm F owner (I retired them many years ago, although I did set them up out of curiosity a few years ago) the "F" is far more about the pure Walsh driver...not the cabinet. And while my current speakers (like the 5000) are far superior to the F's in almost all meaningful ways there are some attributes the F brought to the table that are not easily matched (in my experience) or perhaps not even measurable, let alone exceeded, such as coherency/"seamlessness" .....and that vaunted soundstage that is as close to live that I can recall (outside of a well executed/high quality 5.0 music system). These are singular attributes of a true unfettered omni directional single driver. Indeed, if it weren't for it's well documented limitations of dynamic range/deep bass I could probably happily live with them today.

For me the "F" model has a certain "reverence" attached to it. So, when I got the Columbus sale email from Ohm Speakers that the "F" name had been resurrected I was naturally excited and was hoping that Ohm had figured out a way to incorporate a modern version of the pure Walsh driver most likely with a sub woofer (such as German Physiks, or Huff) but no seperate tweeter. And for only $10,000!!!

So, yes even though the Walsh 5000 is a great speaker I was disappointed to learn that the "F" designation was due solely only to the inclusion of the Ohm F cabinet and not an improved implementation of the Walsh driver technology over the 5000 series. In my opinion Ohms new flagship should be called the Walsh 5015 I assume the subwoofer is a 15" driver). For me the "F" designation is simply "not right".

"For me the "F" designation is simply "not right"."

My opinion is OHM is very consistent. Names of refurbished models (offered for less than equivalent with new cabinets) are based on a combo of original cabinet and new driver names. Hence mine are F5 series 3 and Walsh 2 series 3 for example.

Maybe OHM should retire the F name, like a baseball hall of famer's # is retired?

Also note that the cabinets come from owners who willingly trade in their originals towards new models for significant discount.

Just trying to paint the entire picture,in the interest of fairness.

From My perspective, I am thrilled to own speakers using modern drivers in refurbished F cabinets. Its the best of both worlds for me. I have no desire to live with the limitations of the originals in this day and age despite the unique attributes of the originals.

****Maybe OHM should retire the F name, like a baseball hall of famer's # is retired?***

Well, I don't agree with that. But I believe it would have been more "fitting" if the "F" designation would have been saved for a speaker that employed an "F" like Walsh driver, a speaker closer to the original in presentation and implementation. Why re-brand the 5000 with the "F" designation over a cabinet? Otherwise, any and every speaker that Ohm Speakers have produced since the "F" that employ the quasi Walsh technology (non omni variations with a tweeter) could also have the "F" designation. Why now and why with the 5000? It's about marketing.

Look, this ain't that big of a deal, not at all. But I and several others I have spoken to find the "F" designation for the 5000 to be misleading, if only benignly so. Like I say this is marketing, no sin in that.

I might add that I and others quickly figured out that the 5015 was employing the 5000 driver and not an unfettered "F" like driver when Ohm Speakers kept this new "F" under wraps. Because Strohbeen knows that an Ohm speaker, especially, that employed an improved, more efficient, F like Walsh driver would generate excitement with significant ripples throughout the entire audio community. If it worked, the new "F", like the original, would be an emblematic flagship for Ohm speakers and not merely a flagship.

****I have no desire to live with the limitations of the originals in this day and age despite the unique attributes of the originals.***

Absolutely! Indeed, I replaced my "Fs" almost two decades ago (although I still own them). And I'm sure that the 5015 is truly a great decision. The 5000 on down the line are also "unique" in that they employ variations of the Lincoln Walsh invention. And from what I have heard they are all exemplary performers.

P.S. did you employ your orginal "Fs" up until you got the 5015 upgrade? Or did you have them in storage?

Please note that i posted picture of the mighty 15" woofer.

Well, i find these last posts extremely interesting. To answer the question: I have several pairs of speakers (you can see one in the background of one the the 15" pictures) and I use them all occasionally. The ohm f is the one however I prefer because its sound is unique and still give me the most pleasure on many recordings.

I'm still testing the F-5015 and have yet to make a definitive judgement about it, but I beleive that the F is not only there for marketing purposes. From what I heard so far, the frequency balance is near perfect ( I say near because nothing is perfect), like it was in the Fs. Moreover, the general
Impression of the sound and music is for me in the same family as the original Fs. The pleasure I find listening to the new Fs finds its source in the similar qualities : live like mids, supreme highs, yet not invading and incredibly smooth, bass frequencies which, like it was the case with the Fs, are always at their place, in perfect rhythm with the rest, in perfect rutic and tonal harmony.

Also, like it is the case with anyone listening to the old Fs for the first time, it takes time to adapt your ear to the new Fs sound because as it was the case with the old Fs, it is different fr anything you' be heated before, at least it is for me.

I'm still testing and will be looking at the mid bass when my amp makes it back home, against my other speakers (equipped with one of the best woofers in the world, the Scanspeak 10" paper woofer.

I will have to be very careful in my assessment because as I said the music presentation if the new Fs is so different, with, amongst other things, the 15" expanding the space between instrument and sounds so vastely, that I will have to live with it a while to make myself a definite idea.

Cheers!

Spacer and Mapman thank you so much for your enlightened responses and photos.

Since my following of Ohm speaker development has been spotty over recent years I have a couple of fundamental questions.

I believe (don't know for sure) the W5000/W4000 series are 2 way designs with the Walsh driver supplemented with a tweeter that kicks in at around 12,000 Hz. I suspect that the crossover is of a first order design although perhaps you can offer some clarification on that.

The W5015, I believe is a 3 way design with tweeter, Walsh driver, and 15 inch built in amplified sub woofer that crosses over at 80 Hz. Is the cabinet sealed, ported, or some other design?

Also, the inference seems to be that the 5015 is audibly smoother in the upper frequencies than the 5000/4000 series. This suggests that there have been improvements/changes over the 5000 driver which go beyond just the addition of that awesome subwoofer. Is it known what these changes may be? Or could it be that that the Walsh drive does not have to carry as heavy a workload (because of the subwoofer) in the 5015 that it peforms better.

Thanks.
