How I built my bass traps...

Nope...as long as the density is right the rigidity makes no difference whatsoever.

Thanks again.

Because frames improve absorption as I think I read, I thought the rigidness would change reactions.

It's not the frames that improve absorption. The effectiveness of absorption is a factor of density, thickness and the amount of square footage covered. The frame is incidental, related mostly to form rather than directly to function.

You are my savior mate. Very thanks for the advises.

I just need to get paid or this dream will not come true...

Ok, so I've been really lazy in doing my show and tell side of things but here you go. Thanks to this thread I had a good idea of which materials to use and how to go about building my traps.

A friend and I bought a pallet of insulation material (Gutex Thermoflex) along with a whole bunch of wood pre cut to the lengths we required as we were going to be building the bass traps together. In total we were building 42, 22 for me and 20 for him. During this time my house was somewhat chaotic with stuff everywhere, it's times like that that I really miss having a garage or the likes.





I then set about calculating and drawing out the holes on a template that I planned to drill through the wood. This was a little more difficult than it sounds because I wanted the holes perfectly spaced, even at the joins. In total there are 19 holes on the long piece and 9 on the short piece. I first built a prototype to make sure everything would work out.



I decided I was going to stain the frames black and white as my whole room is black and white as is the material I chose to cover them in.



Keep in mind, to get to the stained stage there was a hell of a lot of drilling and sanding which almost drove me insane!! After the staining I then countersunk holes on the lengths of wood where the screws would go through to keep the frames together. Unfortunately at that time of year in Berlin (summer) it was either very hot or raining which meant some of my wood warped slightly. Kind of pissed me off but what can you do?



Once the frames were assembled it was a simple matter of getting the material in and stapled tight to the frames.

I wanted the material flush with the front panel so I bought some long thin strips of wood and staple gunned through it into the frame to give a nice edge that is invisible from the outside.



As you can see, nice and flush with the front...



After that part it was a downhill run, I just had to fit the insulation into the frames which was a snug fit as I'd deliberately undersized the frames by 5mm.



After stapling the fabric into the top sides I then decided to just sew the back up, it seemed like the easiest solution at the time and worked out really well.



And that's it. A finished product. I had a real deadline as my wife's 30th was coming up and I'd promised the apartment would be in order by the time that came around. So all in all it probably took me about a month and a half to get them all done, it was really a lot more work than I'd bargained on but definitely worth it in the end.

Those look killer! **Love** the frames.

Thanks

From experience, I can tell that drilling those holes into the frame is a heck of a job.
And you did more than me!
