What kind of surround set-up is everyone running with their SEOS speakers?

Just wondering what people are using with their waveguide speakers. Since they give such a good sound stage, are front heights pointless? I'm just running 5.1 currently and am looking at adding front heights maybe. I don't recall ever seeing anyone running front heights with SEOS L/R I don't think.

Also, do you plan on upgrading to 11/13 channels when Dolby Atmos comes out?

Have height speakers, but not installed yet. Will be using JBL Pro 8340's, but may have to build new cabinets for them to fit in my baffle wall. Will probably upgrade to Atmos when it comes out.

I read about Atmos a bit, isn't it just kind of like Dolby's "open source" mastering where you can use a lot of speakers / channels?

Also I'm in the same boat as AV, JBL 8340's for all my surrounds.

Front Center Height, Rear Center and Rear Center Height makes more sense in my room than quad corner heights do.
I hope the home version of Atmos can do center fly-overs with such a config, but I'm not holding my breathe.
That's just my room, every room will be slightly or drastically different.
My fronts are nearly 5ft tall and the ceiling is only 8ft, the front heights would be almost sitting on the speakers like a supertweeter. LOL

My guess is that only the largest of rooms and highest of ceilings, would benefit greatly by wides or heights (9.X or 13.X) above and beyond the current 7.X (which not even ALL BluRay's have, even though the technology is already in place!)
The only way that isn't true is if you are using 13 small bose-cube-like modules in a 6ftx6ft broom-closet.
There just isn't enough space / degrees of separation with pre-existing larger-speaker theater systems like mine.

I'm more excited about a true 60hz or 120hz 3D, unlike the current 24hz BluRay standard of today.
4K 60hz (with or without 3D) would be something to behold too; more so than Atmos me thinks...

I have four Volt V10s, 2 for side surrounds and two for rear surrounds. Cheap Thrills for LCR duty.

I'm using 6 ported v-8 with front heights. I'm still tinkering around with which settings to use, but so far I like them. The LCR is TD12m/SEOS12 which is still on the operating table. From what I have found so far, concerts are killer with the front heights. I have only been able to watch the Dave Matthews/Tim Reynolds BluRay and the Metallica Through the Never, both bring a huge sound stage even without the good LCR in place yet.

I was just wondering how the SEOS would work with Atmos. I can't use my TD12M's/SEOS design in the ceiling because of the direction of my beams. I wanted to match my surrounds, but Atmos presents a bit of an obstacle. The volt seems like a viable option, but not quite what I wanted. Would a different type of waveguide be more suitable?

yeah I wonder if waveguides are needed for ceiling speakers, as they are a lot closer to listening position and don't need crazy volume.

What my original question was and I think some people are reading it differently than I meant, is since SEOS give such an awesome soundstage, how effective are adding all these extra speakers when the SEOS can do directional sound so well on their own. A fair number of people don't even use a center with their SEOS L/R.

Everyone is different. I've had 5.1 and 7.3 and preferred the 7.3.

7.x is my preferred method as well although I have not tried a 9.x setup quite yet, still working on getting the speakers finished for that.

I use 5.1, medium sized living room. I have an Onkyo 717 AVR which supports 7.2, plus wides or heights. I have read that my next best move would be to wides, not heights. Right now I am very happy with the sound stage of 5.1, and I really don't want 7.x.

I have zero interest in Atmos.

I'm considering Volts or the new coaxs for surrounds/heights/wides. From my understanding the Volts are more directional so would work better as surrounds/heights/wides than waveguide speakers. Since front heights are directly above the LR speakers I'm still expecting to get that sense of sound coming from above even though my LCR speakers are waveguide speakers. I think the front heights are suppose to be 3 feet directly above the LRs.


There's a theater with Dolby ATMOS about a half hour away showing Edge of Tomorrow and X-men. I think it's time to get some first hand impressions. Maybe in five years if the format catches on and there's lots of content I’ll add some ceiling speakers and upgrade. From what I read, utilizing 3D sound formats really improves the surround capabilities of speaker arrays. Even if all you have is a headset.

Being coaxial, volts will be less directional than waveguide.

I found heights worked really well for my projection screen. It made a noticeable impact. However I didn't try wides.

Ha! I should have used something other than “more directive” to explain what I meant.

A waveguide has controlled directivity with the SEOS specifically designed to provide good horizontal coverage and to fill a room with sound. Between the coaxial and the waveguide I think you could tell a sound was coming from say a rear left speaker more easily with the coaxial speaker. That's why I'm thinking a waveguide is probably not necessary/beneficial for surround duty.

But I could be wrong. There are people here using waveguides all the way around in their HT setups. Since I haven't purchased my surround speakers yet I was hoping to hear what they think.

All depends on the dispersion pattern. There are horns out there with just as large of a dispersion pattern as some coaxials. Horns are just normally designed as having two different patterns between horizontal and vertical, where coaxials are concentric so they disperse the same in all direction. My Danley horns are actually 50x50 degree dispersion pattern, similar to many coaxials....

I originally thought an DENOVO AUDIO EOS-10 or 8 would have been better for surrounds, but never quite got an answer. bwaslo asked why I thought it would be better over on DIYSOUNDGROUP's forum. I'm gathering he didn't feel it would be better for surround duty over the SEOS12.

The dispersion pattern matters a great deal, but one can't be said to better -definitively - out of context. Some designs might be simply bad based on irregularities in dispersion, but among designs with well-managed off axis frequency response, one dispersion pattern can't be judged always best. The placement and treatment work hand in hand with dispersion to generate the in-room response.

Would fusion 8s that are placed well starting with room design and then laser angled to the main LPs in my big room (36'x25'wide) work better or worse than coax for height, wides, Atmos, side and rear? Opinions ?


Would the bigger room work better or worse for the waveguide?

IMO the traditional monitor design (non-coax) is probably the higher fidelity and higher output design. This makes it preferable all else equal - of course it's not all else equal. The coax has advantages in overall size as well as off-axis behavior vertically.

The larger the room, the less the advantages of coaxes matter.

Edit: if you need/want wider than 90 degrees, you can find that in a coax but I'm not aware of a waveguide that wide.

I would like to do a spin on another proposed design and do a SEOS15 with dual 8" pro drivers below, side by side. Slot loaded to bring down the F3 for a usable 80hz XO to the subs.

Jury is still out on the FL450 thats being cooked up on the Maximus18, but it sounds promising.

I really like the look of the square baffle, and the side by side woofs

I would much rather wait on the Seos Maximus design, and that is what I am doing.

The Seos-15 + DNA-360 + duel side by side pro 8" drivers is already a design that is available to purchase from DIYSG. I believe it's called the Special 88 or something similar. Seems to be a great speaker, although, as I just stated in another thread, I find the center channel to be the most absolute important speaker of the entire system, so going with the Seos Maximus-18 over the 88 would be my preference, although, YMMV.

I thought you were talking about a surround speaker. My plan is to use the Maximus18 as my main 3 LCR, and the SEOS15 with dual 8's as surround channels.

Do you guys have a link to the design i was speaking of.....
