Room coupling

[vitalstates]

This is prompted by a conversation on Saturday evening at eggfest:

In my experience it is possible to transform speakers into a completely new/different sound by experimenting with the room coupling. I have found that by sound treating the listening room the speakers change their characteristics completely.

The real mcCoy is auralex:

and it can be obtained in the uk at:

a cheap version for experimenting can be found here:

I know that in normal circumstances the WAF is about 0.1 on a scale 1 to 100 but for those with a dedicated room it might be worth an experiment.

The most obvious changes I have found come about by identifying the reflection spots and obliterating them. There are further gains however by putting in bass-traps.
