sir kindly see high end models of velodyne ,svs, hsu,rythmik jl, sunfire etc these are some of true subwoofers which can go below 15hzThen, Why home theatre subs and amps never claim to go below 20Hz?
Well to be honest, if you are into MUSIC production, you do take out all frequencies below 40 Hz while recording music instruments. If you are into electronic music then perhaps you may add some music/intruments in the 20-40 Hz section but only individual track.This is fodder for the proponents of "Humans cannot hear sounds beyond 20-20K Hz so worrying about them in music system is futile. Take them out of equation."
