Higgs,

Most DIY traps use rigid fiberglass as the absorption mechanism. The wood panel traps in my plan are a completely different design and work on a completely different principle.

You can do that, but it will be easier to just use rigid fiberglass. And that works well too.

> If so, should the backs be of the same thickness/material as the fronts? <

No, the rear panel, if you do that, needs to thick and rigid and massive so it doesn't flex at all. Such as 3/4 inch plywood or MDF.

Besides the bass trap plans you referred to, see my Acoustics FAQ HERE.
