You said it Mark!!! planning stage pa lang iniisip ko na tunog. Kaya hoping yung ginawa ko na may space sa sides and rear so I can adjust pa. If I need to put additional absorber I'll just pop out the frame then singit ko insulation.
Regarding the rear portion I have alloted 8" of space in the rear, dun ko din ilalagay rear channels and the aircon (split type). The rear portion acts as first reflection too, isip ko why diffusion? diba dapat absorption since it is first reflection. My 2nd row seats are 3' away from the rear wall.

Jay, for first reflection, you can treat that with either absorption or diffusion.
Naalala mo ang HT ni Alvin? Meron syang diffusers sa likod - yung mga slats. Makikita mo rin yun sa "Legends of Jazz." Their purpose is to scatter sound. If there is too much absorption and too little diffusion, the HT will sound too dead. Mawawala ang high frequencies. There needs to be a balance.
In most cases, what is recommended is that the front part of the room is dead (marami absorber) while the rear is live (diffusers). I would suggest you try to put diffusers sa walls sa likod and then cover them with tela. Yun ang ginawa ko sa HT ko. Yun din ang ginagawa ngayon ni Ernie.
Or at least, you can keep in mind that your 8" gap sa likod can also be a space for diffusers. Now, diffusers can have all sorts of complicated designs! D ko na kaya yun.
Cheers!
