  • Room Acoustics

  • How should my listening room ideally be?

    • Does the size and shape of my room affect the set up of my surround sound system?

      There is a direct correlation between your room’s size, shape and loudspeaker placement.

      There is a direct correlation between your room's size and shape and the placement of your speakers. In a "long" room set-up, with the seating located in the middle of the room, it is best to mount the surround speakers on sidewalls parallel to the main seating position. If they were mounted on the rear wall in this room configuration there may be a pronounced "hole" in the sound stage, with sounds "jumping" from front to rear rather than there being a smooth transition. In a "short" room set-up with seating on the rear wall you might get away with speakers being mounted on the rear wall. Furthermore, depending on the distance of the side walls from the listener, you might prefer to use floorstanding speakers as surrounds instead of dipoles.
