Greetings to All - and a Happy Thanksgiving!
Like the title says; I am joining the SEOS DIY club to upgrade my HT.
I am currently running Klipsch all around. What I will be replacing is as follows:

1) First project will be named "BUC" (Big Ugly Center - my nickname), actually a "big Mal" using 4 Auru NS6s.
I have a fixed front screen, and needed a lower profile box to go under my screen. If all goes well; this will replace a Klipsch RC7 that is buried in my overhead soffit (and angled down)

2) Replacing L/R Klipsch RF35's with; SEOS 12 / Delta-light 2512 in sealed boxes.

I have my Aurus, Deltalight 2512s, and the crossover parts for BUC all ready to go. My SEOS12's and 350/360 drivers are on order. I will likely go with one of Erich's flat-pack kits for the L/R fronts.
Below is a sketch of what I hope will become my new center channel:

I am also looking forward to seeing how this turns out. Will this type of driver alignment work just as well as using a regular Seos-12 in the normal vertical configuration?

Not sure how much it will give up to the normal SEOS vertical configuration. I have a fixed screen, so was stuck with going lower profile. Time will tell how much I gave up.

Brought home a sheet of 3/4" baltic birch for the Holiday weekend.
Actually made sawdust tonight, and now have all pieces of "BUC" ready to assemble, EXCEPT for the front baffle.

Tomorrow; I will post photos smile.gif

Reduced a sheet of Baltic Birch to this:

And started gluing it up. The red clamps were just purchased, "Bessey" corner clamps (they work well)

Thanks Guys!

The final dimensions changed a bit.
Outside dimensions are now a follows:

W = 32"
H = 13.5"
Depth = 10.5"

It's starting to become a busy time of year , I will share progress as it occurs.

A little more progress last night:
I will be recessing the back panel, and making it removable. To accommodate this I ripped some of the BBirch into 1" strips. These strips will ultimately be brad nailed and glued around the inside rear perimeter of the back, and will serve as the stop that the back panel is screwed to.


For now they are temporarily attached with some double stick tape. I need to adjust the set back distance of these strips; so that when I add foam weather stripping and screw the back panel on, that it becomes a flush fit.


And as you can see the back panel dimensions are very close. I just need to trim about a 1/6" from the height of the back panel so that it will "just" fit into the box.

Hey Cuzed, for some reason, I didn't pick on you substituting 6" woofer for the 4". I'm looking at your box build thinking that looks awfully big for a Malcolm. Now I get the Big Mal reference.

You are creating quite a beast!!! eek.gif

Thanks! Yeah - it should be interesting. I just did some more cutting, and need to put up some more photos:
I trimmed the removable back panel to fit,
and started on another panel for the interior, for window cross-bracing. Sound familiar? Yes I am stealing from your build, just re-read it this AM smile.gif

Cool. The back panel trimming was a pain. Probably just my crappy wood skills, but I had to do a lot of trimming to get them to fit. Also, don't forget (I did) that the weatherproofing will add like a 1/4" even when compressed. It'll still work, but doesn't look great.

No worries on "stealing" from my thread. It's really a compilation of thread theft, anyway. I learned a lot from other build threads and hoped to pass it on.

Good luck!! Can't wait to hear your reviews.

Java,
I did indeed see your comment about leaving enough room for the back panel sealing gasket. Thanks for noting that in your thread :-)

Big Mal - Weekend Update
Actually spent a couple hour prepping Big Mal ("BUC") for the arrival of my SEOS drivers.

First task was to fit the back panel


Then cut and test-fit a panel for window bracing


After using the sabre saw, rounding all edges with a router/round-over-bit, and drilling for 1" dowel supports


And a test fit of the window-brace "sub-assembly"
(the 3 small black stripes are some sample weatherstrip materials for a gasket seal of the back panel)

Next Up: while I await the SEOS and 350 driver, I might start on the crossover....??

I was a little late to the party, but It looks like I haven't missed the show.
I just got caught up on the main "Hey Guys..." / SEOS thread after being swamped at work, and it feels like Christmas came early.

I also have a fixed screen and have been trying to figure out what to do about getting a center underneath it.
So far this has been a awesome build. I am really looking forward to hearing what you think once everything comes together.
If you to get some pictures of how you mount the crossover in the enclosure that would be extremely helpful.

I will probably start making some sawdust in late January, and seeing this build thread has been encouraging.
I may end up building something similar to this to pair with a pair of SEOS 12 / Designer 12's for my L/R's.

Thanks,

- Max

**How much room under your screen do you have to work with? I am limited to 23"

So far this has been a awesome build. I am really looking forward to hearing what you think once everything comes together.
** Hopefully my SEOS shipment will arrive by Christmas and I will have results to share in early Jan.

If you to get some pictures of how you mount the crossover in the enclosure that would be extremely helpful.
** I will be adding more photos for sure, I'm thinking the crossover will locate just off-center on the window braving, or centered on the floor of the box fastened with industrial Velcro?

I will probably start making some sawdust in late January, and seeing this build thread has been encouraging.
I may end up building something similar to this to pair with a pair of SEOS 12 / Designer 12's for my L/R's.
** The designer 12's sound very intriguing..

Cuzed2- What drivers are you using for this? I am not familiar with the Auru ns6 drivers, are they considered pretty good for the mids? Are you going with the DNA-360 for the CD and then a Seos-12 horn? What do you plan to do for a crossover?

The NS6's are a closeout driver. http://www.parts-express.com/pe/showdetl.cfm?partnumber=299-030

Bill did a design called Daniel, which uses 2 of them and Cuzed2 is using them for an beefier Malcom. Apparently they are very efficient and are quite good for surrounds or centers. MTG has also made a design with a different horn.
