Testing the speaker JBL Flip 6, GT version, in MONO mode (Formerly LFM mod)
P.S: Starting from 3:45 to 6:02 there will be no sound, since KZread has imposed a ban on sound, but from the video you can understand how much the difference in the speaker travel is visible.
This MONO mode, which is an analogue of LFM, is available only on Android devices, if you know how to activate it on an iPhone or Windows, let me know in the comments
And thanks for watching :)
