I believe that TNT has posted a "project" based on this unit, used without any internal stuffing. This would utilize the reactance of the air trapped in the open squares between the slats.Placing some sound absorbing material inside would probably augment the effectiveness of the unit by itself.
However, note that this would still not be a "true" bass trap, it would be more on the order of a brute force approach similar to the Super Quick & Dirty bass traps, where sheer fiberglass volume does the work.
In that sense, simply buying and using the fiberglass rolls as per my SQ&D recipe
(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.html )would be more cost effective, as then all the money would be spent on the absorbing material, and it's absorbing power would not be altered by a semi-open enclosure.
However, I realize that it is not a trivial thing to create a decent looking bass trap, and so, these Ikea units may be helpful in that regard.
Be aware that if I were going to load the Ikea unit with absorbing material, it would be just as effective to use building grade fiberglass, the 705 would be way more expensive, and may not perform as well.
It might also be helpful to know that filling it with the proper density of polyester fiberfill/batting would also do a good job, and side-step the safety issues of loose glass fibers.
What density of polyester would be best? Probably somewhere on the order of 1.5 to 2.5 lbs. per cu. ft.
Good luck!
