Yes, it CAN work, but there needs to be enough absorbing material of a high enough density, or it will not do as much as it should or could.See:
the original post where I reveal the latest Super Quick & Dirty easy bass traps recipe:
http://www.audioasylum.com/audio/tweaks/messages/15737.html
and petew's post where he goes into detail on what he did.
http://www.AudioAsylum.com/audio/general/messages/70817.htmlThe SQ&D versions are approx. 80% the effectivenes of the full blown ASC style ones that are hollow, and a LOT easier to build. However, they use more raw fiberglass, and cost more to make over all. If you take fiberglass, or ppolyester, that has been left to "unroll" and fluff up, and then merely place some of this inside a frame with cloth covering, the amount of fiberglass will not be enough, nor will the density be high enough, to absorb much bass.
Ordinary building grade fiberglass tends to run around 0.5 lbs/cubic foot, while the same fiberglass still in the roll as it comes from the supplier is at a density approx. 3-5 times higher, and thus has a greater capability to absorb bas energy. The SQ&D is literally a brute force method of bass absorption, while the ASC style is the fineese method.
The ASC style "hollow-in-the-middle" type traps make maximum effective use of the materials, using less fiberglass and getting superior results, but in order for them to work, the frames and the construction must be correct, see:
