Soon writing my exam in sound theory, and as half of it is on a self chosen subject, i was thinking about writing one on how to optimize my listening. I'll probably write a part about the acoustics in the room, with some analysis, and what would be optimal, and then about the different options i have to reach that goal. Any ideas on either concrete tips or reliable sources on this would be greatly appreciated. Ohh, and i have a pretty small room, and just got some KRK v8II's. There's a bookshelf (which i cannot move, neither can i change my listening position much) behind me which i'm thinking of noting/using as a diffusor, besides what would be optimal if i had the resources/opportunities.
