To 'test' the FX6021 system, I ran a wide array of audio and sound through them. First a bit of techno; performed very well. The satellites and their combined 12 drivers really deliver on mid to high range sounds. Next a bit of 'booty music', you know, the songs that really call for some serious bass. With my MC Hammer pants on, I was ready to jam. Sadly, when the music played, the bass was very disappointing. A slight bump here and there, but nothing to really get me going."
