I am new in this segment,So can u make these^ more clear?
the satellites use one speaker cone (driver) to play the midrange freqeuncys to high frequency. while the z2300 has 2 seprate drivers, which splits the high frequency and then mid range. so the sound is more precise and pronouced.
the z-5500 has a port which improves effiency of bass frequency, but it isnt designed very well, so it sounds muddy, and 'loose'.
