I've found myself not having to adjust the volume much at all, i leave windows volume at 50 which is also controlled by the G6 and i can change the volume via the knob on the speaker if need be.It's really impressive how they sound, even without cracking up the volume. The bass is good, but without distortion or mudding everything else.
Very solid speakers.
Movies and games here, S350DB where miles better than previous 5.1 Onkyo HT or Sony soundbar.
Playing mass effect last night and the cinematic parts, explosions, warp etc are nice and loud where as the dialogue scenes are at a nice level. Sounds awesome, the explosions sometimes make me jump lol.
