A Sarcastic Statement
Primacoustic Acoustic Solutions
They're Canadian, eh, just like me!
This company makes other bass trapping products as well, but I found these to be something that would pass the WAF (Wife Acceptance Factor) in the "home office" (aka my control room). The ratings seem to look good. Looks like they're using OC705 2" (its 6 lbs density per cubic foot rigid fiberglass). When I called to ask what the ratings are based on, the guy on the phone seemed to think it was with 1 in all four corners of a small-medium-sized room.
I decided I'm going to make some since they seem super easy to make (we'll see if they work). I ACTUALLY found a store that can sell OC703/705 to me...and all this time I thought I had to go states side! All's I need is some fabric and I'm good. Will post pics and feedback once I make and try them out.
In the meantime, as the post title asks, has anyone seen, heard of or tried these corner "bass" traps?

There is nothing wrong with a little shameless self-promotion in the process. There are also very helpful articles on 
Thanks Ethan, I will follow your guidance. I already had the store order me a package of OC705 plain 2" before seeing yours (not sure what FRK means), so I'm hoping doubling the panels to make them 4" thick will yield somewhat similar results as the 4" type. I will try to make these larger as well. May be difficult, since these boards are 4x8, but I will just have to cut other pieces from another board to add together to make a larger triangle...until i can buy the real thing! One thing at a time.
