Materials best for sound reduction (less echo, more studioish sound)

[powerkor]

Im trying to make my studio better acoustically without having to buy the studio foam that ranges in price 100 and up. Im looking into shelter foam (5.00 for 6 sheets 4'x1.5'), cardboard boxes (as the backing), and egg cartons to glue on top of the foam.

I plan on lining the bottom 3' of every wall with this and also to build a collapsable wall that can be placed in front of my drums.

If you know of better materials (more sound absorbant, id appreciate input)

Ummmmmm...... where did you get the design for this treatment?

It won't work.

You need mass and rigid fiberglass soundboard.

Crappy foam and egg cartons aren't gonna do anything to help your situation.

Ahh, yes. The illusive studioish sound! It plagues us all. Damn it! Damn it to hell!
