I got the PAA3 today and have enough 2" 703/Guildford material to make 384 sq ft of treatment and 32 sq ft of rock wool/Guilford. What decay time would I be striving for in a 14x27x 8' (average) room? Use is movies and personal music time. System is Denon AVR4306 for HT; 2 channel is McIntosh C28/MC2125/Pro_Ject RM-5SE turntable. Klipsch Chorus II/Academy/Quartet and RS-7s for the HT and share the Chorus as the mains. Sub is SVS PB-12/Plus2. After breaking my brain for a couple of years reading up, I not thinking straight now.
