open baffle project
 
Here is a project that I have been working on for a while. It is an open baffle "hybrid" two-way design. Open baffle part is an 8" fullrange driver, there is also a 12" sub in a sealed down firing cabinet.
Bla bla bla......here is the build. Comments welcome......




Here is a 3D model of the finished product.

Onto the construction.

A pile of CNC cut parts to be assembled.

First the sub. It is made up of 3/4"MDF layers. The wall thickness of the cabinet ranges from 1"-3 1/2" thick. Very STOUT.

Now for gluing, stacking, and clamping......

Here is the sub cabinet.....minus the two layers that will make up the top.

Same process for the tower.

Here is one sub and one tower glued together and ready for sanding then fiberglass.

Here with the insert in place. The insert will eventually have an exotic veneer applied.

Now for the sanding......

And some fiberglass.

Next is some filler to make sure these are smoooooooth. After all they are going to be painted a high gloss black.

Starting to get a flat surface.

Here is the fit on the insert.

Here is a close-up shot of the Bosse veneers grain.

Applying the veneer.

tower.....

sub......

https://i290.photobucket.com/albums/...e/photo-13.jpg

Here are the pieces trimmed and ready for a lot of clear to get a mirror finish.

Finally attached the base for the tower.

https://i290.photobucket.com/albums/...e/IMG_0535.jpg

https://i290.photobucket.com/albums/...e/IMG_0536.jpg

Here is the base for the sub cabinet. Both the sub and the tower have spikes as well.

https://i290.photobucket.com/albums/...e/photo-16.jpg

Here is one sub/tower ready for paint. The other soon to follow.

https://i290.photobucket.com/albums/...e/IMG_0538.jpg

Notice the sub doesn't contact the tower anywhere. This is to prevent any vibration that the sub cabinet might have from being transmitted to the tower.

Let me be the first (no offense intended)
YOU SIR, ARE CRAZY !!!!

I love builds like this, a lot of thought went into these, you can tell only by the pictures, and the amount of wood, I don't even dare to guess.
Very nice, very tasty aesthetics
Fingers crossed for the sound to be of equal quality

Wow. Amazing work!

Thanks guys.
I made a couple of prototype baffles before I jumped into this. I also spent a good bit of time on the xover. I am very pleased with the sound.

That's genuinely impressive.

Keep the pictures coming, and which drivers are you going to use?

Wow! Very nice build. One question. How did you make that curved baffle?

larryldspkr 20th September 2011 04:16 PM

Holy Mother of Crap!

WOW That's amazing! Nice work, stunning!

>>> Bla bla bla......here is the build. Comments welcome......

It looks ok.

If you are unhappy with the shoddy work and crappy sound, rather than throw them away, i'd be happy to pay shipping to my house and see if i can make something decent from all these parts you cobbled together.

Curious, are you using one or two downfiring subs?
