Let me mention: I am writing here about the speaker 20 category. Not BOSE, YAMAHA not, not B & O !!! The minimum package at first sight suggests worst ...: So small can not be good. After installing 80s music (Funk / Soul) inserted because high damn good. Lo and behold ...: This small subwoofer delivers really good, clear bass and satellite sound clear, almost brilliant. Ok, the acoustic Gourmet hears a certain midrange Lastigkeit, but people ...: We're talking about 20-Euros-Speaker !!! Have already 50-inch speaker is one that were not nearly as good. Sometimes I zocke first person shooter games. That hit me real eardrums wech without the bass wafts or booms. Moderately sound I'm really spoiled, so my conclusion ...: Here sound like 20 60 !!! Is halt Logitech. The building no shit.
