Re: Tritrix HT Build with Ceiling Bracket Design

Holy crap that's a rediculous amount of work! Wow! Fantastic build again!

Thanks for the compliment greywarden. Way up in Alaska I see, wow...

Nicely Done!

Both the write up and the execution of the design are top shelf.

The brackets look well thought out and are a nice touch as well...

Re: Tritrix HT Build with Ceiling Bracket Design

Mr. Soundslike, oh wise one, I've been throwing this idea in my head I cannot shake so let me throw this by you...

I have thought about getting 2 TriTrix sets, using almost every piece that's already cut and creating my own Defenitive Technology BiPolar setup. I would seal off the 5 1/4's with the 2 front firing and 2 rear firing with matching tweets on each side. Using the sealed bottom to throw in a side 10" and 10" passive on the other side. With everything pre cut and using the baffles already cut it wouldn't take much to make it work. My logic is that for $400 I can use everything that's there for the top part. I've even thought about using a 8" side passive for the sealed top to get the lowest response out of the 5 1/4's. I'm curious what your thoughts are.

The ideal filler is one that is strong, never comes out, and sands easily, but I've yet to find it.

I believe the word your looking for is BONDO! It is thought of as an automotive only product, but it works great for projects like this. Sands easy, very hard when fully cured, and doesn't shrink.

You're getting way over my head here, unless you're addressing how the enclosures might be modified and adapted to your project. I do pretty well with the "put it all together and paint it stuff," but as for how all these components would work together, that's probably a question best addressed by Curt. It looks like a very interesting project. Is this the concept you had in mind? If so, I'd build the enclosures from scratch, using the sealed variant, mainly because of size considerations. Were you thinking all four of the mid woofer drivers would be in the same enclosure, or were you thinking of two separate enclosures for them? I'd be curious to know how the passive radiator would work. If this is a viable concept, you ought to start a thread in the Tech Talk forum -- you're sure to get a lot of input on this one.

I'll give that a try. I've seen other posts where builders have used Bondo but I've always assumed there would be a problem caused by different sanding rates (I'm referring to abrasives removing material -- the Bondo probably, I thought, would be more resistant to sanding than the MDF which would leave a bump). I can't wait to try it. Thanks for the tip...

Re: Tritrix HT Build with Ceiling Bracket Design

Don't use bond brand, use rage gold or a similar light weight filler. Bondo brand is terrible. Sand when it's green and it's easy to work with. With any luck I'll have some pictures on my build this weekend.

Re: Tritrix HT Build with Ceiling Bracket Design

This is a fabulous build thread. The amount of work, quality of work, documentation, photos, creativity is just staggering. Thank you.

Coming from you, I'm very flattered, thanks for the compliment. I've followed your projects and admired them all. Outstanding work...

Re: Tritrix HT Build with Ceiling Bracket Design

You, my friend, are leaps and bounds, plus a few giant strides, above me in the woodworking and finishing aspect of speaker building.

I'm just slack jaw awed by your work. Seriously.

Stunning, just plain stunning.

Mark,

That's a great compliment -- thank you very much. Now if I could only live up to it... By the way, as you will recall, I've seen your work and I'm very impressed. We should collaborate on something in the future...

Beautiful work on the cabinets.....hideous soldering:D

Yes RDR75, welding can be challenging at times, to me at least.:o I used a stick welder, a type that doesn't produce the pretty welds that we're so accustomed to seeing made by wire welders. I think I said it before but, I actually did consider not posting those photos showing the welds. They don't exactly improve my reputation, but I thought the photos were needed to better explain how things are held together..., just in case somebody wants to build their own set. You can expect to see better work in the future. Point taken...

Re: Tritrix HT Build with Ceiling Bracket Design

Earlier in this thread, in the area pertaining to making the knobs, I wrote that I had an improved design in mind. Cutting pockets in the knobs where the 1/4" nut will reside, works fine but there are more durable methods. Whenever I adjusted the mounted speakers during the install, I was concerned about twisting too hard, lest the MDF give way. To prevent that problem from occurring, a design similar to the following drawing should be considered. It's more trouble, and depending on which knob is chosen, requires more welding, or acquiring another part called a nutplate. But, once done, there shouldn't be any worries about twisting the knob too hard. In the following drawing, you can see modifications of the original design, that utilize nutplates, rather than rely on a glued in nut. The top Knob involves a little fabrication, and the second two utilize a purchased nutplate -- the second two show what should result if the purchased nutplate is flush mounted and left exposed. Knobs with brass and black screws are shown.



Oops..., looks like I somehow drew left-hand thread wood screws... Anyway, to continue, the nuts used in the first knob are called "coupling nuts" or "extension nuts." They're commonly available anywhere hardware is sold.

http://www.dhcsupplies.com/store/p/3...l?feed=froogle

In the drawing, the coupling nut is welded to a disc cut from sheet metal to make your own nutplate. Cutting and shaping the discs will involve more than a little elbow grease, so substituting a large fender washer might be a more attractive way to go, if something suitable can be found. But, it will likely be difficult to find one with a large enough diameter, and a small enough center hole. Or, you can buy a nutplate, such as this one, available from Rockler. Note that 5/16" threaded rod would have to be used in the cross piece since a 1/4" type is not available. This option would also need a spacer between the nut plate and the vertical straps.



Although not shown in the drawing, trim pieces could be made and installed over the nutplates for a finished appearance. If the purchased nutplates are used, and mounted flush, they might very well offer a nice look, left exposed without trim pieces.

If I make another set of these brackets, I'll use this design.

Actually, I was talking about the soldering on your crossovers.
...but I'm probably a little jaded - in my line of work I regularly have to inspect class 3 electronics construction - the type used in military applications....
