DIY Bass Trap....Will it Work ?

[Bluum]

OK, no answer.
A more direct question then: Will it help with a membrane absorber?

I'm thinking of this design:

Based on a 3mm (1/8") thick plate with dimensions of 60x120cm (24"x48"). About 2/3 full of insulation.
One in each corner behind the speakers.
It is a sealed design by the way.

No effect? Better or worse than a "superchunk" design?
Is this one too small?

It's a waste of a good corner IMO. If you have a live room, you need Full Broadband absorbtion - not something 2 octaves wide at most which is what a real membrane will give you. Do you have any idea what this trap tunes to? Do you know how to calculate it? You give the thickness of the front but don't specify the material. Without knowing the MASS of the front, we can't calculate anything. Also, the absorbant should be within 1/2" of the membrane and likely only needs to be 1-2" thick. A chunk like that behind a membrane of that thickness is most likely a waste of material.

Normally, membranes are used at the ends of a specific dimension where a specific issue is identified. For instance, you might use a membrane in the middle of the rear wall of a room to kill a length related issue without adding more high frequency absorbtion.

Also, you may find that you'll get more and better responses if you start your own thread instead of coming in at the end of someone elses.

OK, I don't mean to be nagging people.

And no, I have noe idea which frequency this one tunes to.
I'll start my own thread then, that might increase the responce as you say
