What's the largest center channel you could get away with using? As in how wide and how tall.

Do you think the center channel components need to be at least as big as the left and right speakers?

I like where this is going. lol

Me personally without an AT screen, I could roll with something like 44Wx14Hx22D or so and put my 65" tv on top of it. Might as well make a beefy tv stand with that monstrosity integrated into it.

Love the looks of the clearwave 4cc se, and imagine something larger than that with your SEOS designs.

If possible, I do indeed prefer the same size speakers all around for LCR.

I also believe LCR should match if u have the budget and space for it. Though I am a fan of matching speakers for all positions including the surrounds.

My goal for my living room theater is to integrate a monitor-sized version of my upcoming seos12/td12 towers into the TV stand, with the woofer box built in and the waveguide in its own box sitting on top in the usual center channel spot. DIY media cabinet slowly under way. I'm somewhat surprised this isn't done more, you just need a media cabinet with a 15" wide space in the middle, and rip out any shelves in the way. cool.gif

So I guess the answer to Erich is, something the same size as a typical sealed 12" SEOS kit but in two cabinets. biggrin.gif

I concur. After hearing what a large center speaker can do there is no way I would ever go back to a small center with 4'' or 6'' drivers. I can say using a large center made more of a dynamic impact with my setup than any other single purchase.

I think it should be identical to left/right speakers. Larger the better. Mine is 50x30x18

My TV is wall-mounted, and I use the top of my conventional TV-stand to hold my center speaker, so I have quite a bit of room to play with as far as your typical horizontal speaker designs - I could go about ~44" wide, and a height/depth of about 20".

Tweeter should be identical. Size, just for me due to room size smile.gif...about 48 wide and max height 24...I gotta go look, but isn't one of your friends doing a Seos horizontal with dual 10" 16 ohms ? That's the bad boy i'm waiting to see smile.gif)))))))

I always try to get the bigger of the center channel a particular company have in their prospective model line, at one time I one B&W 802N, I went with HMTS3, not the biggest they ever made but it was freaking huge, and solid. Before that I owned Dali Helicon the W200, and the center was very impressive as well.

Now I have Ascend Towers, I've matched them with the Horizon center, it's almost the most perfect center I've ever owned.


In genaral always get the biggest you can fit, and afford imho biggrin.gif

Like Starquester, without an AT screen, my max would 60" (w) x 24" (H) x 24" (d) which basically would replace my entertainment center.  I also like the beefier look of the clearwave 4cc se.

It should be the same as the mains. My speakers are 44x22x22 including the center. If I had the room my surrounds would be the same so as of now they are 19x20x22.

hey erich,

another possibility came to me this morning. not sure if it is a new idea or a recycled idea. doesn't matter. :-)

i'm not sure what to call it. 2.1? horn crossed wherever (1-2khz?), mid runs from horn cross all the way down. additional 3 drivers roll in for mid-bass.

the essence would be to use only one driver next to the horn as the midrange. this would minimize off axis cancellations that would occur from using two midranges located next to the horn.

then, to bring the sensitivity up and provide good impact, 3 additional drivers would all be crossed in somewhere below the cancellation point of the outermost two drivers (the point where the difference in distance from each driver to the listening spot is 1/2 wavelength).

of course with something like this, the off axis response to each side will be slightly different, but it may not be a deal killer.

the listening window will be much wider than if the mids to the sides of the horn are both used.



so, not an optimal design, but nothing is really optimal anyways. seems like it may be workable.

the big advantage is of course the vertical height is minimized and that seems to be what a lot of folks want.

it is also a symmetrical *appearing* design and it is undeniable that people prefer aesthetic symmetry.

i'm sure some of the other guys will weigh in.

Listen. It's All Good.

Which size do you guys think makes the most sense:

12.5" x 29"

13.5" x 33"

15" x 30"

15" x 35"

Is 15" too tall for most people?

i have like no room. i could do something thats like 6 inches tall and pretty wide and deep.

height kills me.

does someone make a 6" coaxial? that might actually work

ideally id have more space and just build a 3rd tempest

If possible, they should be identical if not very similar. By it's definition, at least marketed, the center channel is a compromise.

I like the size of my new ones. biggrin.gif

I would love to use a Tempest 12 as my center to match the mains but the extra height from the ports on the bottom kills it. If we could get a version with side or rear ports I think it would work well.

There is a speaker nearly complete with 6" woofers similar to what LTD02 posted. But it uses some fairly expensive parts. A cheaper version might be coming.

There's also a design already done from a new speaker designer using four 4" woofers with the same compression driver as the coaxials. And yet another using four 5" woofers.


But we need something beefy, I'm just not sure how large to go because of the center channel. The center channel pretty much dictates the left and right speakers for this design. They will use the same exact parts.

As often, there are just too many circumstances and variables to account for. I would just go for something "beefy" as you put it and most can design or re-design around it.

To me, the TUX1099 is the perfect center channel. Most because it is only 12" deep and 12" wide. Don't give a crap about height since i'm AT.

I must be guilty because people say I am guilty because they chose to call me guilty because they refuse to see the truth. Much easier to be part of the mob..

Quad 8's or 10's? Or would that be sonically overpowering in conjunction with mains that have single 12's?

22"H, 14.5"W, 16"D, the center is the same as the L&R, except I hang it upside-down above my plasma... By going upside down, the C-C of the waveguide throats are within 10" vertically across the fronts. It's VERY nice, especially coming from a previously weak center channel. I'll NEVER use a center that's different from the L&R ever again.

The deltalite kit uses a baffle that's only 21" tall. I built my center channel Tempest with that 1ft3 box and it sounds identical. Just gotta persuade Erich to make the cutout fit the Tempest woofer.
