I'm dropping it one star for a couple of reasons.
1. There is no included absorption chart included. which other T Akustik absorbers do have.
2. There is no hole for screw mounting, according to the instructions it seems that adhesive is the expected method, which I dislike
However on the plus side, it seems the material is strong enough to support a screw mounting.
The wood-looking stripes are actually made of the absorption material and it's a very handsome panel on the wall.
If they made matching bass traps at a similar reasonable price, I would certainly buy them!
Oh and they also do a good job by the way :)
