Hey guys...we need a little rallying here... - Page 68

All my speakers are rear access. Its very easy to do. Im doing it with my new QSC build. I molded the QSCs right into the baffle, no seems at all now.

Build the box normally then cut out the access you want on the back. Keep the piece you used and glue it to a 1/4" MDF piece that fits flush on the back of the speaker. 1/4" MDF is easy to sand down to very thin/smooth corners that blend really well on the back of the speaker.

I get that and I was planning to do the same with the big roundover box. It doesn't look like there will be much surface area for a rear access panel on the Seaton box due to its triangular back. That's not an issue with the QSC WG, but the SEOS will be an issue.

I gotta say that the SEOS will look great in that box. In fact, that speaker looks nicer than Seaton's Catalyst and JTR's T8/T12.

Yes, its the QSC + TD15M kit that Mark will be selling. Im definitely curious to what his CD will be. Mark has already posted that it won't be the DE250.

My back is triangular too, its only 6" wide....Still enough. Why isnt that enough. how are you going to mount the SEOS? I would still think you mount it/glue it/bondo it on the front??

I just couldn't tell how much width is available on the back of Seaton's box. I also wouldn't want to take a router to that box and accidentally gouge it. I'm sure that if Seaton makes a box for the SEOS, he will include an access panel for driver mounting.

I don't get the access issue either - both woofer and SEOS mount from the front.

Thanks guys! I was very happy with how it took form. There are a few more pictures in the group buy thread on AE's forum. Do note the woofer was just the closest thing I had on hand, and has a different cone and phase plug finish than the TD drivers. The front vertical edges have a 1.75" wide, 30 deg bevel with 6"x6", 45 deg bevels on the rear corners. The rear panel is still 8" wide, and could easily accommodate up to a 7" wide access hatch on the rear if warranted, which should clear any compression driver of interest. I'm not as big a fan of having to glue parts without mounting holes, but it could be easily accommodated with the CNC's accuracy. After there is confirmation of what will be run, I'll look at making the SEOS an option in the enclosures.

But the SEOS is glued in and I would want access to the compression driver somehow. I guess it might be possible to access it from beneath via the woofer hole.


Thanks for the details. Do you know when you will have price figured out?

Why couldn't SEOS be screwed in?

I thought the SEOS was made without screw holes. Am I wrong?

Drilling holes is pretty easy, no?

I don't know, if they aren't countersunk I don't think it would look so great and if you are spending the bucks on a box like this I'd imagine aesthetics will be pretty important. As nice as the box with the QSC looks, I don't think the waveguide screw holes look so hot. They don't look terrible, but it would look better without them. I'm pretty sure this sentiment is shared as it is the reason there aren't pre-drilled holes in the SEOS.

I believe there will be holes pre-drilled. Most asked for that.

The waveguide is mounted on the front but if someone is doing a complete baffle with the waveguide, they are going to bondo over the waveguide edges,sand smooth and paint to make the SEOS become just part of the baffle. Im not a fan of screws and the PA looks of the waveguides.

In doing this, we need an access through the back of the speaker so we can bolt on the CD. I also do not mount my woofer on the front any more. The depth of the waveguide is usually 1 or 2" more then the center of the woofer so to have a better CTC I set the woofer back. It also removes the bad looks of the woofer gasket.

This is pretty much how I did my last QSC and how i will do any new horn design.

You can't countersink?

so you countersink

Did you guys forget about what else I'm working on?

Obviously these dimensions will be changed a bit. This is just one style and size.

Oh, for some reason I thought most people wanted the smooth look and that won out. I tend to forget things. If that is the case, then it is no big deal.

Hmm....I thought that there wouldn't be pre-drilled holes in the original fiberglass ones. Personally, I'd rather not have holes because you can glue the WG to the baffle. Also if you want to free stand the WG then the holes are unsightly and would have to be filled which would detract from the pristine gel coat.

Erich,

Looks good! What CAD program are you using?

-Roy

That looks great Erich. I would prefer something like that.

No holes on the fiberglass models. Holes were discussed on the plastic ones though.....so everyone's right!

Rajacat, I'd barely be able to draw a square in a CAD program! The front baffle was a project I'm having the guys in Poland help with. I have ideas, I just can't do CAD work. It takes a little extra time because sometimes things get "lost in translation". But we're getting there.

More projects are coming, but they can't be discussed until we get further along with the other companies. I'm sure they'll be trickling in all winter long........

I might be interested in a version suitable for AE TD6H.... or a flatpack kit or something.

I agree, no holes in the fiberglass waveguiudes. For those that need holes simply drill and countersink. Fiberglass drills neatly and can easily be done with a hand brace.

Eric the baffle looks good, but what about different woofers with different OD's. If the baffle allows rear mounting then slight differences in OD will not be a problem and the front of the cutout can be bevelled or radiused which would match the other radiusing and, I think, look very good.

Only short self-tapping screws would be needed to mount the woofer. Fiberglass is immensely strong, so much so that if the pilot hole is too small its possible to shear stainless steel screws right off.

I think a slightly taller baffle with a bit more baffle below the woofer may look nicer by reducing the squat look of your proposed design. Just a few inches needed.

As Eric just posted its the plastic ones that will have holes. Sorry for any confusion, I thought the plastic version was the only one being mass produced first.

I have asked Eric for a rear mounting woofer baffle design. I agree that rear mounting allows for flexible CTC changes.

Except now I think Erich is leaning towards ditching the plastic version due to the risk in tooling costs (which I think is wise BTW). Maybe the FG version could be done both ways.

For an exceptionally nice looking cabinet like Seaton's, I'd love to see the hole-less version. If I'm putting them in my baffle wall though, I'd much prefer a version with mounting holes.

Maybe it will be easy enough to drill the holes yourself if needed.

Im with you, I wanted to remove the idea of holes all together because then it removes the flange issue.

The full baffle is still being worked on. I've offered up a few different designs, nothing is set in stone.

Should I start a new thread to discuss dimensions, mounting options, etc? Or are there enough interested guys in this thread? New one might be better, I don't know.


By the way, the SEOS™ samples that are going to speaker designers will be shipped in the next few days. Here's what I have coming on that order:

At least 1 pair of each:

SEOS™-6
SEOS™-8
SEOS™-10
SEOS™-12
SEOS™-15
SEOS™-18


See, I'm keeping things moving!

ooohhh....can't wait to get my samples!!!!
