Impressions of Coincident Speakers

Wanted - Impressions of Coincident Super Victory III

Would like to find individuals owning or hearing the Coincident Super Victory III (or other similar Coincident Speaker Technologies speaker) and / or the Devore Super 9 speaker.

I am in the market for a new pair of high sensitivity / high-flat impedance curve speakers with a nominal impedance of 8 ohms or greater. 1st order crossover, highly dampened woofer, etc.

I’m researching Devore Super 9’s and Coincident Super Victory III, so if you can describe tonal accuracy, treble and bass specifics, scale, stage/image, coherency, etc would very much be grateful for you taking the time to add to this forum your views on these speakers. It will mean a trip to SFO to listen to the Devore Super 9’s and since the Super Victory III’s are sold factory direct, my only option to purchase of these speakers would not include listening to them, buying unheard (so to speak). I’m wondering if those 12" woofers are more tame then what a sealed subwoofer would normally provide. My current speakers follow the base line with well defined and articulate notes; and thats what I am looking for. I have neighbors, and knowing I may be disturbing them with thundering room pressurizing bass distracts from my listening pleasure. I have an REL R305 sub for those times when I want to feel the kick of a bass drum and need the option of turning off subterraining bass. Coincident specs the speaker goes to 28Hz and the woofer is well damped for tube amplification. Any views / info regarding bass of these speakers would be very helpful in my selection between the above reference Devore and Coincident


My current speakers are Sonist Concerto 4, Genertaion 2, driven by 30 Watt P/Pull Class "A" (mostly) EL34 (Ars Sonus Filarmonia, with Jupiur Copper Foil / Bees Wax coupling caps)

Front baffles of speakers are approx 5’ from front wall, 9’ apart tweeter to tweeter, 3’ from side wall (center of tweeter to side wall. I sit 10 to 12 feet from front baffle of speaker. Opens up to kitchen behind where I sit, about 22 feet to wall behind my seat. So basically the entire area is 15’ wide X 37’ long, speakers on the narrower wall (15’)

I have purchased a LTA ZOTL 40 Integrated W/ EL34 Mullard tube upgrade. The LTA will be the primary amp in the new set-up.





Hi Bill.

To better understand the speaker and room interaction you encountered while configuring your room to achieve the resulting SQ; would you please provide your room size, What type of wall, ceiling, floor material, etc.. Dedicated room or multi function., etc

Thanks again for all your time and help. It's a definite benefit in helping me make an informed decision.



I just believe that the more scrutiny applied will uncover concerns about literally any speaker as none represent perfection. 


Your right, I do have a tendency to open rocks to see how they work


Woofers, firing in or out - ?. Sonic differences between the two positions?




@bradf @hilde45 ​​​​@charles1dad, thanks for your kind words!  Now then, my room is a second floor bonus room that has been appropriated as a dedicated listening room and is roughly 14-15 wide, 20 ft long, and with 8 ft ceilings.  I'm using a short wall orientation, and my rack is behind the listening position.  Amps are on the floor right next to the speakers, keeping the speaker wire as short as possible per Ralph K's instruction. The room is nicely symmetrical forward of the listening position.  The flooring is a really nice Luxury Vinyl Plank over OSB, and the ceiling is fairly heavily treated above the listening position.  I have a clever arrangement along my side walls that deflects sound from the first reflection zone back towards the front of the room, so that I have suppressed most of the reflections in the 8- 20 millisecond range that is most responsible for compromising image.  This is a much better solution, in my opinion, than using absorption at first reflection points.

I have the woofers facing outward, with the outer edge of the speaker about 32 " from the side wall, and with the speaker about 30" out from the front wall as measured to the back of the cabinet.  I found, on my flooring, that the speakers performed MUCH better using Herbie's footers that using the Coincident supplied spikes. 

Outward firing was much better in this room than inward firing.  I suspect that having the woofers firing towards each other in a narrow room gives too much cancelation due to out of phase waveforms

If one is not careful to dial in speaker position and the main listening position, these speakers are capable of inarticulate bass.  If one is careful, they are capable of nice articulate bass.  This just isn't a speaker that you can plop down anywhere and get it to workup to its potential.

The Auricaps are a nice improvement over the Solens caps. I've used them in other crossover rebuilds, and they offer a nice performance at reasonable cost. The tweeter cap in the SVII is an 8.2 mF cap, so they aren't going to be cheap.  I went with Jupiter coppers and have Duelund Silver in parallel.  The Jupiters are humongous and went for about $550 a pair.  The Duelund Silver parallels added another $200.  If I were doing this again, I might try the VCap ODAMs for the tweeter. 

This is a tough call for you.  If you don't have the luxury of a dedicated room, you are pretty much playing Russian Roulette with any speaker you can't return.  Every speaker, regardless of design, is going to have an optimal placement and relationship to the main listening position in a given room, or said in another way, no speaker is going to reach its potential in a given room if you can't accommodate the optimal position.   So you will be wanting to find a speaker that is happy with what you can give it.  It is essentially impossible to predict that a priori.  



It's been a long time since I heard some coincident speakers.   But when they were the "new thing" back in the late 90's a local dealer carried them and I always found them way too colored for my liking.  Hence I wasn't surprised by the notorious Stereophile Review:


I don't know if the designer has upped his game since then.


At the same time I really like the Devore O speakers which some say are colored as well,'s pretty subjective.   I don't know where one hears coincident speakers these days.
