Ohm Acoustics Walsh F-5015 speakers


Hi everyone

I too received the msg stating that Ohm Acoustics in Brooklyn is having a Columbus Day sale. In the message there was a mention of the new Ohm F-5015 speakers. Upon reviewing the site there was no mention of the F-5015 speakers. I then saw in the forum a couple of members inquiring about these speakers in the main Ohm Walsh thread. I figured for these new speakers they deserved a thread of their own.

Well what do you think these F-5015 speakers are? My guess is that these are the latest generation of new drivers/speakers to replace the original large Ohm Walsh F drivers. I'm thinking these speakers will be enormous and sound awesome.

Any thoughts/comments are more than welcome? If you get in touch with John Strohbeen about the F-5015 speakers feel free to post your findings.

Thanks

Hi rclang

The ohm f-5015 has the most powerful low end I've heard, but it not only powerful it is also extremely faithful to the sounds recorded. Weather it is the double bass in Beethoven 5th by Karajan in 1962 or the more recent extreme bass of kangding ray album, or a duke Ellington big band recording, the bass is always perfectly fitted with the rest, and the rest is so dynamic compared to the old f that IMO ohm has really made a giant leap in sound reproduction, miles ahead of any other brand of speakers.

Moreover, I know I can locate it better in my room and regime the adjustments the 5000 offers, as you can see on the picture.

I have a pair of ohm, but I do not listen to it anymore since I got these marvelous new musical boxes.
Hi blueranger,

One of my mono block just let me down this week, but when I get it back I will try them with another pair of speakers equipped with a Scanspeak 10" woofer and let you know how it feels pressure wise. I can already tell you though that they will not withstand the comparison.

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.

Tweeter kicks in at ~ 7khz as I understand it. Not sure about crossover type.

"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? "

Yes, 3 way as described. Not sure about crossover point or controls ie similarly adjustable or not to an outboard sub or more fixed. Spacer might know or I would have to study the pics of teh controls he provided further to venture a guess.

I suspect the cabinet is sealed and not ported like other Walsh CLS designs, in that sub would relinquish benefits of a portm but not certain. Spacer would know. If not ported, that would be a first in the Walsh CLS line I believe and more like original OHM F.

"Also, the inference seems to be that the 5015 is audibly smoother in the upper frequencies than the 5000/4000 series.

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."

My understanding is it is a standard configuration 5000 driver used based on the descriptions I have read, but John Strohbeen might be the only one to know for sure. Also, I believe he has indicated it is currently a prototype, so details could change.

One of the benefits IMHO of the standard 2-way Walsh CLS driver (all generations) is that the Walsh driver does most of the work and CLS design seems to minimize demand on the tweeter. This helps account for the Walsh CLSs ability to go very loud seemingly with little or no compression (with enough power behind them), breakup or distortion, that I have observed both with originals from the 80's and the newer descendants.

Adding powered subs to any speaker otherwise pretty much always translates to further lowering the demand on the rest. German Physiks uses this approach with their DDD Walsh driver. I know other OHM Walsh owners (MartyKL for one)have expressed considerable success using external subs with other OHM Walsh speakers, especially to help enable the OHMs to perform well off of tube amplification.

I use an external powered M&K sub with my Walsh 2 series 3 OHMs running of 180w/ch SS Tube Audio Design 125 Hibachi monoblocks in my large open family room/kitchen area. The sub crossover frequency and level setting is minimal with the OHMS, compared to how set with my other monitor speakers I have used the sub with from time to time.

The sub definitely adds something, but I could probably live without it. THat room is fairly big but not huge and is my second system where I do not do as much critical listening.
Hi reclang

It is a scealed design. For the rest of your questions, I suggest you contact John via the Ohm site. I'm sure he will be able to answer them.
Spacer,

I know this is an old post, but, if you have time I would still love to hear your thoughts on the F-5015's. I had a pair of Walsh 4's I purchased in 84'. Upgraded them to the 4.5000's around 2012. Had John and co build a custom center channel for me, then lost everything in the 2018 #campfire.

Now, I'm in contact with John to build me a couple of F-5015's, plus some additional speakers. So, any more insight you can provide would be helpful. Are you sending full range frequencies to the 15"sub, as well as the cls driver? How has the sub amp performed through the years? Do you find it not necessary to breed an additional sub for movie listening?

Thanks, buttecreeker
I had a chance to get one in 2012 that was being beta tested. I regret I didn't take John up on his offer but I had just spent my money on a bigger amp. Oh well maybe I will have the funds one day to get one. He said it goes down to 16 Hz for some scary bass.
Well, once I get these in house and start playing with them, I'll report back with some feedback. The speakers are the final piece of the puzzle for my system rebuild. My hopes are that an additional sub won't be necessary for movie soundtracks.
Sorry for your loss in the fire, that was all quite a sad time for many. I hope that things are well with you moving along from it! Better times for you! 
As to the F-5015’s, if you have questions or thoughts on setup etc., give John a call, I am sure he can give you as many tips as possible! Not that it hurts any to poll the audio population either! Have fun!
