Mattias from Helsingborg, Sweden. Sound absorbers.
The sound absorbers creates an impressive centerpiece above the sweet spot while at the same time fighting the firsthand reflections coming from the speakers and bouncing off the back wall, behind the sofa.
When it comes to the acoustical effects Mattias writes:
The sound becomes much more focused and the music is more calm :) Truly well spent money - especially compared to buying new cables and similar..."
