Tom's comments are correct, and the references are excellent as well. However, one aspect that Everest does not address (and rightfully so as these books have to have their limit) is how to handle this issue with different types of speakers. Planers, bi-pole, di-pole, and rear ported speakers all react differently to front wall diffusion and absorption. The front wall can actually be used almost as a tuning device. When you get the correct balance of diffusion, reflection, and absoption it can be bliss. The reference is very good on discussing how to calculate the total room absoption and diffusion and discusses how to balance it very well. Most people tend to overdamp rooms thinking that getting rid of more reflected sound will leave the sound that was intended by the speaker (or other) manufacturer. This rarely (virtually never) works as there must be an appropriate balance of frequency attenuation and diffusion over the entire frequency spectrum. There are also some good software programs that can help with this as well, such as the CARA 2.1 (which our company does sell, so I do have a vested interest there).
