Received my Sub Mini yesterday. Installing it was a piece of cake. I connected it to my Playbar. Performed Trueplay. Heard no difference in TV sound, whether speak or music. Toggled Trueplay on and off. Heard a difference in sound of the Playbar, nothing from the Sub Mini. Toggled loudness on and off. Heard a difference in sound of the Playbar, nothing from the Sub Mini. Toggled Sub Mini on and off. No difference. Tried various combinations of these parameters. No difference. Tried all of this at 2 different locations; one underneath the Playbar and one abt. 3 meters away. No difference. Throughout testing bass and treble levels at zero.
Then connected it to my 2 grouped Play:1's. Performed Trueplay. Once again: no difference in sound. Performed Trueplay. No difference. Toggled Trueplay on and off. Heard a difference in sound of the Play:1's, nothing from the Sub Mini. Toggled loudness on and off. Heard a difference in sound of the Play:1's, nothing from the Sub Mini. Toggled Sub Mini on and off. No difference. Tried various combinations of these parameters. No difference. Tried all of this at 2 different locations; one close to the Play:1's and one abt. 2 meters away. No difference. Played music from my library, mostly flac’s. Then played music from Sonos Radio. No difference. Throughout testing bass and treble levels at zero.
Made sure the Sub Mini is working by feeling the cones vibrate. They do.
Called in the wife. Let her listen to all configurations. She didn’t hear any difference.
Called in the son, who’s quite a bit younger than I am so has a better hearing. Let him listen to all configurations. He didn’t hear any difference.
The only time all three of us heard any difference, is when I changed the Sub’s audio setting from level 0 to +15, then the Sub Mini was audible. When I changed from 0 to -15 no difference was to be heard.
The “helping you feel more immersed in every scene and song” and “a richer, more powerful sound experience all around” were nowhere to be found. The next couple of days I'll keep on trying and experimenting, but if it stays like this, the Sub Mini is going to be returned. Really disappointed.
