Humn, I'm 3 to 4 meters from the speaker depending on where the sofa and media reck is that day, so.
But well, what can I do.
When they are not loud enough, the surround sounds incomplete, and becames a gimmick,
-15db is the minimum i can say i can have any more fun than just using the tv speaker, that well, aside from bass, might as well go higher than the ammount I'm supposed to go with those, now, on daily tasks, -25 is really fine, but on a dedicated time for a movie, -10 is probly what I'll go with
