This Infinity Hardrock 210 gives a deep disappointing bass as I felt. Although the specification says that the subwoofer has 20-120Hz frequency range, what I felt, the sound around 40Hz is mostly attenuated and below that it is hardly recognizable. That is the real deep bass what we sound lovers know. I bought it after reading some reviews, hoping to replace any of my older sound systems, logitech, creative and sony. However it is no near to my expectation. My money got wasted:-(, and I am still thinking to repair my old sony system to satisfy my need of a decent response across the audible frequency range.
