Could you say a few words about the bass traps?  This is something I'm thinking about currently.

Count me in about these traps, very interested in how good the work, what they do and where to buy.

Hi!

Sorry for a late reply but here it is

The panels behind the speakers are homemade BAD-panels. The function is described at link below:

It´s a combined absorber/diffuser. The panels does an excellent jobb at mid/higher frequencies (not to effective on bass I´m afraid since they are not that thick, 5-6 cm). I had a big problem with reflections in my room before, and those panels are making quite a difference.
I´ve tried to make those as discrete as possible, and also portable. 
The build is quite easy but the holes (I think there are about 1000 holes/panel) was quite a pain to drill

I´ve built these with instructions from a Swedish site, but found an english site that seems to be equivalent:
