Actually I came from a 5.1 full HT setup, but since I live in the Metro and condo living is our preference, sakto yung ganitong setup.
I was at a low 40s sa volume when I had a AVR and separates. With a soundbar I'm at 50's to mid 60's sa volume percentage.
Plus, subok ko na talaga yung Sound Projection ng Yamaha. Pwedeng pwede na. (Dapat lang at that price though)
HTH!
