Hi all , I currently have a Yamaha sound bar that's rated at 120watt power output , ideal listening volume is near 80 on the volume slider , my living room is about 13ft X 12ft and I sit about 10ft away from the TV , I'm worried that if I get the gen 2 beam that it won't be as loud because Sonos don't specify the power output , does it go fairly loud ??? Considering the size ??
