Ohm Super Sound Cylinder SSC-4900 initial thoughts kinda review


Recently, and partly on the basis of what I read in these pages, I purchased a pair of Ohm Super Sound Cylinder (SSC-4900) speakers. By sharing my thoughts I aim to give back here but also to provide some information I wish I could have found out when searching high and low for information on these speakers. 

Long story short I am getting back into high-end audio. I once had a pretty impressive and well curated system. For years I lived without. In the Fall of 2019 I upgraded to Amazon Music HD, which led to a pair of Audeze headphones and a headphone amp/dac. After a while I wondered how minimal of a good sounding system I could build. Some parameters I set for the speakers were they had to be full range, play loud, sound good, image well with a wide sweet spot, look good, and be less than $8000 per pair. Oh, and they had to work in a large room with hard surfaces.  

Somehow I stumbled upon Ohm. What little bit I could find suggested they were possibly right for me. More than anything the overall gestalt that they were uniquely good drew me in. That, and the seemingly reasonable price helped seal the deal. It is, however, a major issue that even though I live in the seventh largest city in the nation there was no way to see or even audition these (or really anything putatively good) before buying. Mail order is not how I bought expensive audio stuff in the past. Well, some things change. Another issue was a near complete lack of audio press on these speakers. How can a company so old, and so well thought of not have oodles of reviews from the usual suspects? 

Ok, so, after some back and forth email with Ohm I resolved to get the Super Sound Cylinder aka the SSC-4900. For some reason the speaker is listed as a Beta product on the website. Seems to be a sorted consumer product not a beta. Anyway. Clearly, any interaction with the website affirms that Ohm cares little for the website, which I can dig but it really is quite frustrating. I even had to email to find out what the switch on the back of the speaker does. I'm still not totally sure, but the switches are in the upper most position for what it's worth. Something to do with deep bass EQ and my large room size.

I had plans for a media server/dac/amp all in one. That seemed a wonderful in a minimal way. Some products of the sort are supposed to be pretty good. Well, some don't yet work with Amazon Music, and some seem to have clunky software interface, but none were powerful enough to drive the Ohms (by all accounts). Ok, so, have to get a beefy power amp. Bummer right? Big money coming on a Krell or whatever the kids buy these days. Extensive search later I ended up buying, again on very little information, an Apollon AS1200 ICEPOWER class D amp from Slovenia. Mail order all the way. Go big or go home, right?

Another long story short I bought a Bluesound Node 2i. I had, in fact, demo'd this product so I had seen it, and knew a bit about it. Importantly, it works with Amazon Music and the interface was not too clunky. I hoped it would actually work okay and drive the Apollon with at least a moderately functional volume control. I could always get a separate DAC and preamp later, right?

Got some 12-gauge MonsterCable and some cheap Audioquest interconnects. Played the cable game before. Not again. 

Speaker one arrived. A week later speaker two arrived. Had the Bluesound. Did not have the amp. Crap, okay, so I hooked up an old-ish Denon receiver the AVR-X1100 with 80 W for each of 7 channels. Great functionality in that amp btw. Before the sound, however, a word about my first impressions of the speakers. Arrived in big boxes that barely protected the speakers. Obvious hand work/cost savings. One of the metal hats was bent slightly but I'm not gonna fret. Unnervingly lightweight speaker for its size. I paid five grand for what? Honestly, the materials don't feel very magical, the fit and finish is not stellar, and the appearance, well, subjectively not too awesome. The wife did not even notice the lone speaker hanging out in the corner at first. In short, these do not look or feel like five grand well spent. But, how do they sound mister long winded?

Through the Denon receiver the Ohms did not sound very good on average. Sometimes sounded kinda okay but generally not. The Bluesound was a breeze to set up BTW. Nice bit of kit that. Perhaps the Denon could not handle the Ohms low sensitivity or impedance or so I wanted to believe.

Miraculously, the Apollon showed up two days later. Nice build, or nicer than I expected, and 620W per channel. SIX HUNDRED AND TWENTY WATTS PER CHANNEL. If, as they all said, the Ohms needed power I should clear that up with this thing. Yes by Jove, the Ohms need power. The Apollon is there and not there. I can't hear it, but it made the Ohms stand up and fly right. Things were looking up. 

I've tweaked the speakers position to be closer to the wall. They need that, they really do, which is actually good for the wife acceptance factor and with having a 5 year old kid around. Imaging is funny. It can be precise. It's not all that deep (yet?), and it's not as wide/listening position invariant as everyone says. For sure, it makes a difference where you sit. That said, the best listening location is bigger than what you get from a mini-monitor. Treble is nice. Inoffensive and perhaps lacking a bit of sparkle but far from bright. Bass, deep bass that is, is listening position sensitive. These do not plumb the depths the way I wanted them too or, indeed, the the way I was led to believe. They may benefit from a sub, which I am loathe to add. Midrange is pleasant and present, perhaps somewhat seamless maybe due to lack of crossovers. I like vocals on these speakers. Seems like they will play loud, but I've not really gotten a chance to try that yet. 

So, to sum up my first impressions... These Ohms sound better than they look. They need tons of clean power, are best close to the wall, and are not champions in any one area. They do seem quite musical as they say, but I would not go as far as some reviews and say they are super close to "being there". I like the sound, but I really had to give them a chance. They have gotten their two fair shakes. I still have about 110 days to return them. Probably won't. Need to play around a bit with placement and hear more music. Maybe I will try a big pair of Maggies. What? No, can't/won't pull them out into the room. For now, it seems I have a pretty nice and pretty minimalistic setup. Two speakers, one amp, and one other box that plays the music from a huge online library. Clean, cool, and never have to turn it off. 

Did I get what I wanted? Will the Ohms make me forget and just play the music? Maybe. I might still be an audiophile after all and the Ohms, while seemingly good, are not unicorns with sparkles and glitter farts.

I learned about Tidal only after getting back into the audiophile press. Have not been able to sort the value proposition versus Amazon Music HD. 
Thanks mapman. I am actually noticing the sweet spot takes some getting used to. If I open or close my eyes or move around in the room the sweet spot as it were changes. I think I do have to grow accustomed to it. 

I got to listen to some higher volume today. Scared my cats, which I admit was kinda cute in a sad way. The sound was really great. The Ohms stayed really well composed. They just got louder.

I also placed them yet closer to the wall. Got more bass. Deeper bass. Could feel the bass. Might try putting the mystery switches in the middle position.

As I learn more about them I am getting more impressed and happier with the Ohms.
trudat, lucky that you got to actually hear some of the 5000s or any Ohm for that matter. Glad you liked them. 

I debated the 4900, 4000, and the 5000. Evan at Ohm recommend the 4000 or the 4900 based on my queries. Said they would sound almost identical. With the switch the 4900 can be used in various sized rooms whereas the 4000 is just for large rooms. Like the 4900 I guess the 5000 can be tamed down from good for very large rooms to smaller rooms. As I recall I thought that 4900 was the best compromise between performance, price, and aesthetics. 

I've been tinkering with the setup. Everything sounds good to very good plus at this point. Things are really looking up at this point. Little changes in the speaker positioning can be easily heard.
mapman, I believe they have 4000 drivers but there is only one switch with three positions. According to Ohm its a deep bass booster switch to account for room size. 
@spiritofradio can you share with me here the links to the recent video reviews of current Ohm speakers? Can you suggest another full range speaker I can place close to the wall? I'm open to switching. Also, I can't see any reason to get Tidal in addition to Amazon. I also have Spotify (free) and Sirus XM radio (paid). 

@avsjerry I'm liking the Ohms the more I tweak their positions. I'm gonna give them time to marinate in my mind for sure. Regarding the weight I understand that they can build a rigid speaker in a round shape with different materials and less bracing etc. That is cool in a way. They do, however, sort of present it a more beneficial to them than to the customer in terms of manufacturing ease and cost savings. They are easy to move around and unbox. I just pulled them up and out by the plastic with one hand. My last speakers weight 200 lbs each so the mass of the Ohms was a surprise. There are other little niggles with the fit and finish that I won't belabor here. They look fine. Some speakers in the price range look better but whatever. With the bent hat set at a certain angle it hardly shows; probably only to me.

@cmckasty I've never heard of the Shahinian Obelisk. A brief Google search suggests that they are a very old design perhaps not available now??? Anyway, if they need to be out in the room they probably are not for me in that room at this stage of my life.

@djones51 what did you buy to replace the Ohms?
@spiritofradio 

"just search in YouTube"

I did, I have. You said negative reviews were out there. I asked you to share because I've yet to find one.

"I really don’t want to get into a pissing match with the crazy old farts on here about who’s favorite speakers might be better for you.  
Dude you made a very well articulated plea for help.  You were fishing for somebody to just be honest with you and so I threw you that lifeline.  
There are fantastic speakers that work best against a wall or in a corner.  Do a little of your own research and you’ll find one."

I can, and have done research on my own. I asked you to share since that is doing research and you seemed to have some ideas. I don't see how that is getting into a pissing match, this is my thread and I'm not pissing on anyone.


@dep14 Thanks for your thoughts. I can only alter the speaker positioning. There will be no special room treatments this time around although I appreciate what they might do. 

While everyone says the Ohms are not the most detailed speakers available (and I basically echo that) they paradoxically manage to reveal even small changes in positioning. That, and the switches on the back of the hat make a noticeable difference too. It seems then that they are very revealing but not uber detailed for whatever that means. 

Now I've got them aimed more or less at the center of the room with the switches in the middle position. Bass was too boomy from one listening position with the switches up. Makes sense with the instructions since my room is large not very large. 

At this point the Ohms are outstanding and vexing almost in equal measure. They can sound fantastic but not always. Certainly, the source material matters. But I find images, that is, voice and instrument localization can move around seemingly based on my concentration/head tilt/eyes open or closed/or whatever. In one notable case imaging was better than I've ever experienced from any system at any price. Vocals often sound palpably realistic and also sometimes lack warmth sometimes at the same time. The volume levels they can reach before you are aware of just how loud they are is almost incomprehensible. I do like to rock out.

One limitation I have is that they sit astride a cabinet that holds up the TV and contains the media player and amp. According to Ohm they speakers like to see each other. The only way for me to do this is to pull the speakers out from the wall more than the recommended amount. The closer I've put them to the wall the better they have sounded and the more they disappear physically into the room. Can't see pulling them out.

I'm very interested in your Salk experiment. I did consider them but like the Ohm it's a mail order risk.   
@dep14 

Seems like great minds think alike. Yesterday, I had some time to play around with the positioning. Wanted to see if pulling them out past the TV stand/cabinet would improve things even if the bass suffered. Ohm says the speaker like to see each other. 

I immediately noticed a big positive difference. As mentioned by everyone (and me) these speakers really show every small change in position, much more so than conventional front facing speakers. I have no experience with open baffle designs but I suspect they are also tricky.

Then I again boosted the bass with the switch back up to the upper most position. Then a slight toe in adjustment. Voila!!!!

Now I have consistent, mostly precise, wall to wall imaging with some depth. Satisfyingly deep bass response without bloat or boom. Smooth and detailed midrange with an incisive snap/fast leading edge transients. Pleasant and satisfying if not airy, and certainly not bright, treble. They sound pretty darn good now. Really amazing actually. 

Low sound levels make be happy, this can do background music well. But I can also wake the neighbors, which is lots of fun. This great sound just gets louder. Amazing actually. Some songs that when played loud I know, I expect most setups to get congested (even expensive kits) just get louder with the Ohms. The composure at high volume is super fun and not just for rock. Symphonies and even chamber music benefit from near realistic SPL.

Thanks to all for chiming in here. I can heartily recommend the Ohms. Now time to enjoy the music.


@maxnewid that's awesome. Seems like you are getting good results. The Ohms do love juice. I also considered the Peachtree. Are you close to the wall or out some? How about bass switch position? Toe-in?

I was rocking out last night with my 5 year old daughter. There are still many albums I've not yet heard on the Ohms yet. They constantly surprise me. "Time" on DSOTM actually scared me. Was not paying all my attention to the music and the alarms going off were so realistic it gave me an anxiety attack ha ha. 

It is so easy to locate individual instruments in space and pull them apart acoustically. Accurate timbre and weight and attack makes for some realistic or at least highly satisfying musical experiences. The cohesiveness of the sound is also beguiling. Having essentially one driver really seems to work out well.
