Like the music mode's response, see little point to the others. Since when does 50Hz not propagate through walls and wake or disturb people? My last system's sub had a mute. Mute on the AVR controls and a mute button on its remote. I took it for granted that subs would have mute options these days, but it seems many don't. I see this one appears to not have one. A mute for a sub is so necessary in homes it should almost be a legislated requirement that no subs be approved for sale without a mute option, plus the ability to turn it down to zero, using a remote or app. What's up with companies selling below 20Hz subs into urban and suburban domiciles with no capacity to press a button to turn the thing on or off? Don't they realize most people don't want a sub on all the time, when everything that makes sound is connected to it and pumping out deep sound 24/7? Don't they realize the wife will lose it if we bring home a sub that can't be muted? = no sale.
