Bass Traps that do just that!

bwo you are wrecking heads here. cm is centimetre. Your plastic sheet is clearly one millimetre 1mm.
The sheet needs to be bonded to the fibre batt using Spraytac glue or similar.
The LF absorption bump is pretty broad.

Sorry for the confusing. Not sure what I was thinking. I meant 1-3 mm (millimeters) of course.
Will plastic (1-3 mm!) differ much from FRK when it comes to reflection of frequencies?

FWIW, thin plastic is what is used on the front of Real Traps.

Aah. So the great secret is revealed.
My guess is that it works better then FRK when it comes to reflections of frequencies above bass then.

Not a secret at all. This video shows pretty much everything that goes into making our products:

Made in Connecticut

BTW, the plastic we use is very thin.

How thin Ethan? Less than 1 cm?

Great video! Too bad shipping to Norway is ridiculously high. Do you need a retailer in Norway?

You mentioned in the video that you use fiberglass that have four times higher quality then mineral wool. Can you eleborate?

bwo,

those traps look pretty good.

if I were you, next time I'd just cut a sheet of plastic the size of the face, and spray tac it to it. don't bother with folding it around the edges. any high freq bouncing around in that 45 degree nook between the wall and the trap, you're gonna want to get rid of that anyway.

Thanks for the advice. The way the pictures show are a very easy and a cheap way. They also become very light. I'm also considering building them with a visible frame. They will look better with a frame, but become much heavier.
What's the best way to tighten fabric and membrane if I build a frame? Use only spray tac/glue or tighten it with some plywood on the inside of the frame?

How many do you think you can sell, and how little markup are you willing to accept?

I said the 705 rigid fiberglass we use costs us four times more than mineral wool.

As a humble Viking I'm willing to accept a very small percentage. A large portion of demo models are important though for a good sale.
