4" insulation housed in 2x6" board frame?

Meant 1x6 in the title, not 2x6

Hey all,

I'm considering grabbing some Knauf 3LB 2" insulation, and doubling them up to make some bass traps.

I was curious if it'd be a good idea to construct a frame for them out of 1x6" boards rather than 1x4s. It'd cost ~$5 more per panel, but would enforce an air gap of 2" + distance from the wall.

Is this a smart idea, or are 1x4s with a mounting-distance based gap the better way to go? Would the panel weight increase significantly?

1x4's are usually 0.75" x 3.5" so if you are going to make 4" thick traps, you need to use 1x6's which are 0.75" x 5.5".

You can rip off the extra 1.5" or keep it for a air gap.
