New house, using sunroom as HT. Elac Debut b5.2/c5.2/b5.2 and in-wall, in-ceiling to flush out 5.1.2. Difficult room to work with. 14x14x9, windows cover 2 walls (left and front w/blinds), 1/2 open along right side into larger area, couch against back wall 12' from cc, 65" Samsung TV. Old ears and damaged hearing make HT dialog a challenge. Have done the basics - speaker positioning, rug on floor, chairs to help absorb 1st reflection, EQ, DSP, avr settings, etc, etc. Not much room for panels except back wall behind couch. Don't listen loud, mostly on/near axis, 95% movies/TV.
