The scene opens with a young man, drill in hand, loaded with a counter sink bit. He stands nervously over a perfectly good 24" waveguide, hands shaking before drilling the mounting holes......

ahhh crap, I can't get myself to drill these things for mounting. I drilled one of my other ones and now have exactly three that aren't drilled. Anyone see an issue with silicone mounting and being able to use a utility blad to cut them out and clean up for reinstall if driver changes, etc are needed??

Ya, I'd just go for it.

Whatever method you use for attaching the waveguide make sure it is really secure. My method of using brackets at the corners is not the best as you can feel the waveguide move with bass heavy material and only a hundred watts or so. Lots of surface area for that pressure to push against. I would say use at least 10 screws if going that route. eek.gif

Separate chamber?

I think they are talking about the Waveguide to baffle connection?
post #1272 of 1502
The CD almost touches the rear of the enclosure so encapsulating it in in it's own chamber would eat up a lot of enclosure volume. It just needs more then 4 brackets in the corners to hold it down. Actually now that I think about it my brackets have gasket material on them, that along with the gasket on around the waveguide leaves a bit more play then there should be, so screws even if only in the corners may do much better at keeping it secure.
post #1273 of 1502
Excuse my previous posts, lack of sleep and excess of stress lately...

Now for something helpful, Bob Crites makes brackets for both 1.4" and 2.0" CD's: http://www.ebay.com/itm/Horn-and-Driver-Support-Bracket-for-1-4-inch-Exit-/380451199667?pt=US_Speaker_Mounts_Stands&hash=item5894a89ab3

I'm using the 1.4" with the inside of the front lip of the SEOS 24 resting on top of the midrange cabinet, no issues so far.
post #1274 of 1502
isn't there a way to rig something up with a couple of threaded rods where as the bolts are "tightened" they push against the inside of the baffle on one end and push the inside of the cd or a little cd jig thus "pulling" the waveguide up against the cabinet?
post #1275 of 1502
have to use your imagination a bit on this one, but something like this:

red lines are threaded rods

blue squares are bolts (washers not shown)

brown is a wooden block or something that mounts around the waveguide cd mount/cd

gray line is the baffle

as the blue bolts are tightened in opposite directions they would push the brown jig back thus "pulling" the waveguide into the baffle.

I think they are too good looking to drill up, but then again, its not like you will see them anyways.

The more and more I think about it, I may as well just drill them all. I'm thinking a screw in each corner, one in the center of each side and two additional across the top and bottom, Silicone would probably work, but make for really messes removal and re-install. I'd love to think removal and re-install aren't ever going to be needed, but who are we kidding, they will biggrin.gif
post #1277 of 1502
Couldn't you just epoxy on some bolts on the waveguide?
post #1278 of 1502
Jake - Drill that b*ch!!! All this time spent discussing fastening could be valuable time spent listening. biggrin.gif Use some nice black anodized fasteners if you're worried about looks. You could even do t-nuts or some other type of insert if you want to make it extra sturdy.

10 weeks to go until the GTG. biggrin.gif
post #1279 of 1502
Use a center punch or nail to indent all the drill spots first so the bit doesn't dance on you.

As far as the waveguide moving during use. How about wrapping the back with rope caulk and covering it with gorilla tape?

Here is an example of how I wrapped the ones I used when I built the cornscalas.

Ahhh, the voice of reason biggrin.gif

Yeah, I'm drilling em'. I think the fact that they aren't "readily available" is what made me so nervous.

BTW, Brandon and I had an interesting discussion last night about how many ceiling tiles are gonna have to come down to put 8ft tall speakers in your room biggrin.gif We may not be able to run the quads, I hadn't even thought about that

spot on with punch...to much possibility of slipping on the waveguide without a "dent" to start the bit in. I plan to wrap them as well.

Yeah, we were discussing the same thing last night as well. I believe I have 7' 11" from the carpet to the ceiling tiles but that is not including any stands you would want to use. It might be easiest to integrate "just" the twin 15s anyway with the limited time we will have for setup and placement with each setup. BTW hit me up one of these nights so we can discuss what you need to get your stuff set up in the front of my room. I know I have twin 20A outlets/lines up there for amps and a L/R RCA run already from the receiver.

7'11" would do it, as the top woofer is only at like 88". No stands necessary. I'll call you later on to chat a bit. Hopefully the quads would be fine tuned to the point that it really wouldn't take any extra effort except the time to plug in the detials on the dsp. We could always run through the duals, all other speakers and then if there is time like in April when we let the Noesis rip, just do quads then. Somehow though, I don't think there will be much "extra" time, plus it will be nice to hear them all without worry about only getting a few minutes on each speaker.

I'm just getting nervous now and want to be sure I have all my ammo biggrin.gif

Yeah, redesigned and built the top and bottom modular pieces so the quads will go on Andrew's stage without height issues. I have to post all the pics, was waiting to get the prep work all done and post a series. I will update soon. Can't wait to finish them and get going on the room construction.

+1 . Just cut threaded rod to the desired length , put a gob of epoxy thickened with microballoons or just saw dust, glue the studs to the waveguide and bolt from the backside.

Just a little teaser....I will put the next set of pics up once I finish the prime/paint. Wanna keep a little to the imagination biggrin.gif The below are pics of the top and bottom modular that I've put together just for Rilla's GTG in January in order to fit the quads on his stage. The bracing isn't installed the way it shows, just sitting there while the glue dries..

Haha...I honestly keep beating myself up becuase I feel like I could have done much better on these. My workspace is soooo limited while waiting for our house to be finished. My dad is kind enough to let me use some space in his garage, but it's so crammed full of crap it's tough. I wanted to do these with some nice contours and a "higher end" finish, but it will never happen until my space is done...by then I'll have these hiding behind the screen and I'll have no desire to do anything but listen to them biggrin.gif

C'mon man, everything looks great! I know how it is though...we are our own worst critics.

I can point out little imperfections in my HT that no knows are there except me. They bug me, but no one will ever see them unless I point them out.
