Audio

How to choose the first receiver? Looking for Yamaha YST SW-030, Yamaha yst-sw315 or similar active subs for my 16m room. Acoustics - Edifier R2700. In films and sometimes in music, there is not enough "airy" bottoms.
NOT audiophilia, NOT major, NOT connoisseur of your unique sarcasm.
Map - Asus Xonar D2, if anything.

Dadada, it's good that they warned ... :)
Look at the real consumer characteristics.
There are 7.1 channels, there are 5.1. But 2.1 is enough for a room of 16 meters, because even at 30% the volume will become PPC to everything.
Next, we look at such a thing as an audio reverse (aka ARC ). Do you watch movies? So look, so that he can receive sound from the TV set via HDMI in the format that the TV set itself receives, directly unencoded, and not squeezed to disgrace (optics), and not by analogy (tulips). We connect the TV to the port with audio reverse and get the bonus control of the receiver from the TV (on / off and volume).
Perhaps your particular TV does not know how, but I'm powerless here.
Then you open your movie via SmartTV or cable, turn on the receiver in the sound settings, it wakes up, receives an audio stream and broadcasts.
I also suffered, but in the end I took the Pioneer ...
