panel traps

[figurehead]

does a panel trap have to be connected to a wall or can they be moveable boxes

reason is that i have 2 of the same size boxes made of plywood i think its 1/2" and the dimensions are roughly 3' tall 2' wide and 1' deep

i was wanting to know if this could be turned into some type of moveable trap or if i should just cut them in half and seal them to an existing wall.

also for another situation in the room i would like to somehow take advantage of is the fact that there is another empty garage on the other side of my right wall, and where there use to be a door way which is about 6" deep i currently have a piece 3/4" plywood covering the door way which is just about 4x7. is there a way to turn this into a panel trap or will i have to get a thinner piece of wood

lastly is ther any value as far as bass absorption for a raised floor of about 8", that is not sealed

thanks for the help
always appreciated

Figs,

Yes, panel traps can be built with a back instead of using the wall as a back. But the back must be massive and rigid so it doesn't flex as the front panel moves in and out. Also, there's little point in making small panel traps. You need to cover a lot of surface area for any bass trap to do much, and it's hardly any more effort to make one that goes from floor to ceiling versus only a few feet high.
