Put ~$400 into these - have an overkill 2x4 frame in the back, then wire holding in a bunch of mineralwool triangles. According to my GF, they are not pretty, but they work really well IMO.
They need to go asap, so I'm offering them for free. Since they are a gift horse, you need to come to my place in Chicago and pick them up.


they are not horizontal:)
