To be clear, the hardness or sibilance I heard was mild and could be attributable to the other components, or the room or the music sample. What I did note was that the speaker has no controls. This is somewhat of a disappointment—an L-Pad makes it far easier to integrate a speaker into a particular system/room. I know manufacturers are reluctant to include them because customers often don’t know how to use them and complain about the sound, but, I think it is better include controls.
