MDO?????

#1 Post by Badblood »

I was in my local big box store the other day grabbing some plywood for a project I am working on and came across some MDO.

I have never used it, but I did a little research on it and it seems like some pretty tough stuff. I did a search for it on the forum to see if anyone else had ever used it, but got a blank.

It doesn't seem overly expensive, but it is a bit heavy. Just curious what peoples thoughts are on using it for cabinet builds.

At least one outer surface/face is paper.
Since it is well stated in the forum not to use ply with a thin outer veneer (because that could delaminate), especially for sub builds, I would think it's not suitable...
Built:
DR 250: x 2 melded array, 2x CD horn, March 2012 plans.
T39's: 4 x 20" KL3010LF , 2 x 28" 3012LF.
WH8: x 6 with melded array wired series/parallel.
Bunter's Audio and Lighting "like"s would be most appreciated...

Then there's the question of how the glue will stick to that surface. My guess is not well at all.
In build order:
O12 with no tweeter.
3 x WedgeHorns.
2 x Jack 10 without tweeters.
2 x DR250.
2 x 16" T39
1 x Tuba 24
2 x SLA Pro (sort of...)

Seems the boat builders say it takes epoxy extremely well (penetrates the resin) but our PL Premium doesn't penetrate the resin so it floats on top and makes poor joints.

That's too bad, MDO is water resistant and has a beautiful finish for painting.
Built:
17" width 10" driver Autotuba
2 x 29" width dual Lab12 Tuba60
6 x DR250 2510/asd1001
In progress:
2 x DR250 2510/asd1001
For best results, point the loud end of the array towards the audience

That sucks because it looked pretty decent for the money.
