They Look like logitech z506's. In a totally please do not set them up like that arrangement. The center speaker is facing to the ceiling, the front satellites are facing the back of the monitors and the rear satellites are facing forward. Ideally put the center speaker on the desk. The front ones can be placed to the sides of the screens inwards or under the screens on their sides. The rear ones really should be behind you either mounted facing the front ones or facing each other on opposite walls behind you.
Don't auction it off for charity and maybe we'll find out. Now its been bought up. I loved MCM's Gramps build. That is precisely the sort of vehicle modding I like. Sleepers.
