Kallax (Ikea) Bass Traps?

Hi,

I was thinking of buying a couple of these and filling them with some 60kg mineral wool. Then cover the back and sides with material. (Leaving out the middle shelf when assembling).

They're made of chipboard basically; would the sides reduce the effectiveness? They're not solid inside...only a few mil thick...maybe I could drill holes in them...

I'm basically only after stuff below 200Hz with these...

Honestly, I couldn't buy the wood for that price, but more importantly don't have the facilities to make stuff...but basically the idea is a soffit trap, sorta like those GIK soffit traps (which I can't afford; enough of anyway...I am going to buy some for the actual soffits...these are for ground level).

...cheers for any thoughts.

Hello,

You don't know how is made the soffit bass trap.

Do don't waste your money by buying ikea product.

Make panels with plywood and rs60 with the good thickness and a great area.
Don't hope a great performance under 100 hz.

I know, there could be an air gap, or something diaphragmatic...

The standard way to make these seems to be to have all four sides open, and solid top/bottom...I wonder if the solid (ish) sides would make them less (or more!) effective.


TBH, I was going to buy four of them anyway to use as table legs/storage.

Making wood stuff isn't going to happen. And the wood would cost as much as that unit!
