Tri-traps are awesome! Easy to place, inconspicuous and powerful absorbers.
I like to place them flat along the floor, against the sidewall, one end at the speaker baffle the other end coming forward into the room. This has worked excellent in three (very) different rooms. Then balance a 244 on the tri trap edge at the first reflection, or back farther near the baffle to better quiet down the whole room.
Good luck with the sale Bryan. It is rare (if ever?) that GIK has a sale. Prices are already lower than anyone else. I sound like a shill, but just a happy customer.
