My L-Shaped desk points into the corner of my room. So all 4 speakers sit on the desk. The "rear" speakers are at the far corners of the L so that they are horizontal with me which has a semi-surround sound effect. I realized that If I reversed my desk and pointed it out towards the room, I could mount my rear speakers on the wall behind my back. So yea, if you have the room, make your desk face the middle of the room / entrance instead of a wall.
