Auralex

I've got some wedge foam and such. It's good for high/mid absorption but even the bass traps sort of suck for low end compared to resonators or even semi regid mineral fiber (which auralex makes too).
 
We looked at some of their products in an advanced acoustics lecture at university the other week, they are really good.

Now I need to go back to revising for and exam in said advanced acoustics course, yuk!
 
Auralex is pretty much what everyone uses when building a typical home studio. I think that it looks cheesy. I'm very interested in the panels (like Andy has), though.
