Hi,
Your amp goes to the 5000 cone, which takes care of frequencies above 80 hertzs, and the built in 500 w amp takes charge of frequencies from 16 to 80 hertzs with its 15" woofer. |
They are in fact incredible. Totally different from all the other speakers you have heard before. |
Hi,
I have a pair at home for trial and will let you know my conclusions if you are interested in hearing them. My own speakers are upgraded ohm fs, which are the best speakers I've heard so far. I'm hoping the new fs will surpass my old ones. And after a week of playing with them, it looks like it is possible they will. |

Hi,
I listen to these two or three hours every day. I just found the right location in my 600 sf room today. I had been close for a few days but I think I finally got it right today. I've listened to a few Bach cello suites and I was quite impressed by the speed and depth of the 15 inch woofer. Frankly, I never heard a recorded cello sound as good as the one I heard this evening.
So far so good.
Regards,

Hi,
Sure they are powerful, but I now start to believe that they are also capable of generating the most subtle nuances at all frequency levels. I just listened to the fabulous Herbaliser's Session One album, and all the density of the rich arrangements was there and very impressive. I then listened to the dire straights On every street, where all the rhythmic arrangements were evermore present without taking anything from the very live sound of the master guitar player.
I will go into deep bass music tomorrow or this weekend and will let you know how it goes.
For those who wonder what system i use :
Oracle mark I've turntable
Mark Levinson 436 mono blocks
Accuphase c-280v preamp
3d lab millennium mark 3 dac |
I know many good speakers owners will say that, but the question is : can a speaker handle real deep bass (like for example in the album "The last resort" from Trentmoller or in the last Kangding Ray album "Pruit Igoe")so well that all the high and mid frequencies are still as smooth and present as if there were no bass, with no degradation whatsoever.
I have tested the new Fs and they can acheive this as well as they can reproduce a piano, cello or violon solo in a really emotional way.
The last test I will perform is compare them to my old refurbished Fs (the best speakers I've heared so far), in my new home (600 sq f room). The competition is tough, but I think the new Fs can actually come out on top. |
I'll start testing Sunday. One of the question I have is this: the new 15" woofer can go very low, we already know that, but it is not only a question of going low it is a question of also doing it right; since the 15" has a 500 w/c amp, I'm wondering if this amp will produce a bass of a quality equal or superior than that on the old Fs 12" with my mark Levinson 436.
Also, the sound dispersion of the old Fs is unique and addictive, I wonder if the new Fs will offer a similar stage or if it will be a more central stage.
I'll have some suggestions a to the answers to these questions by the end of next week. |
Mapman,
You are probably right. I know where to place the new ones in my new room, but have not yet tried the old ones. The will probably have to be spotted differently than the new Fs. |
Hi,
Im going to keep the new ohm Fs. Of course they sound different from the old ones, but the new ohm f sound is fascinating in the sense that they offer a new approach in the sound dispersion, an aspect which was central in the appreciation of the initial ohm f.
The new f sounds extremely good with all kinds of music, which is a exploit by itself. The deep bass is not only as tight as can be but it show new textures in records I thought I knew by hart, thanks to the 15 inch woofer.
The f5000 is just incredible offering a extremely detailed and musical performance, which is perfectly matched with the 15 inch woofer capabilities.
I'd never tought if do that, but I'm going to bring my old Fs to John this week end and I must admit it is not going to be easy letting them go.
But hey, we got to follow progress and the new Fs represent progress IMHO from the old ones. |
Hi unsound,
They are restored properly, but they are part of the deal for the new ohm Fs. |

Please let me know what is your system.
Happy thx giving - even though we do not celebrate it in canada |
You guys have got me thinking if I should not after all keep my Fs.
Concerning the renovation of the fs, i use to make speakers and even sold a few so I know that even the smallest changes can modify the original sound of a speaker. The changes which were made are the following;
1) The foam inside the cone and the surround (suspension) of the cone has been replaced by the exact same foam by a technician who has been doing this for years.
2) the top is now bolted to the bottom with four bolts instead of only two
3) the amp is now connected directly into the cone instead of in the bottom connectors placed at the back it the cabinet, so the inside wiring is no longer used
4) the connectors on the cone have been changed for modern connectors (I've tried many while I was making speakers and I chose the most neutral ones IMO )
5) the quantity of the damping material has been slightly reduced after several hours of testing (two inches were taken at the top)
So you see I've kept the changes to a minimum. I know there is some guy who restored them by changing the cabinet completely (type of wood and thickness of the walls - the result is not an ohm f anymore since it is impossible that with such changes the speaker sound anything ode to the original Fs. |
I forgot to mention one change;
The foam joint between top and the cabinet was changed |
Correction: in the new Fs, my amps take care of frequencies above 80 Hz and the Ohm 500 w/c built in amp takes care of frequencies between 16 and 80 Hz. |
Mapman,
Since it is not yes in production, I will ask John if it is ok with him; if it is I will post all the pictures you mentioned with pleasure. |
Hi Mapman
Hi asked John and there is no problem to post pictures so I will try to post some this week end. |
I have the pictures but don't know how to upload them to this thread.
Can someone help me? |
Mapman
I have no clue on how to built a temporary site. So what I suggest is I email you the photos and you create the site. Let me know what you think |
Hi Mapman
I've built a system under the forum "done for now" I titled
"Ohm F-5015 photos"
Hope you can find it. All photos are there. |
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. |
I will post a photo of the woofer soon. |
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. |
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!
PS: note that English is not my first language, so please try to read the ideas not the words. |
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. |
