For a boomy room, what panels will reduce mid-bass

A nice and inexpensive way to tame you room is to purchase a nice decorate 5
x 9 rug and hang it from the wall behind the speakers. I use a couple of pieces of carpet tack strip and nail that on 16" on center and then just hang the rug from that. I have one on the front and rear walls. Cheap and can look very nice as well.

Good luck

While a tapestry / carpet hung on the wall looks nice and tames high frequencies by absorbing them, it'll not reduce the room boom of lower frequencies that the original poster had enquired about - it's too thin and there isn't enough of an air space behind it.

If anything, hanging a tapestry carpet on the wall will reduce the high frequencies and throw the sonic spectrum further out of balance and exacerbate the room boom problem.

That has not been my experience. My guess is that with the system in question here we are not talking low bass but 120hz. The usual suspect.

panels from ready acoustics go down to the forty hertz range, they are cheap compared to most others , and look great. good luck.

You can select pattern perforated acoustic panels. Because acoustically this type of panels are very effective. Please visit http://www.acousticmanufacturer.com/Pattern-Acoustic-Panels.html to have an idea of this type of panel. They are providing very good looking & acoustically effective perforated acoustic panels at a very competitive price. Thank you.
