this have 2.1 speaker with a optical input and a hdmus input that will work with you typical hdtv . even better , the subwoofer include a receiver build into it , which be why this compact system will work right out of the box . and that also mean far fewer cable go every which way too . it have analog input too , if need . the sound be very good though as other point out the satellite be the weakest part of the whole system . there be a adjustable graphic equalizer to make the most of the system 's ability however . all in all I be very happy with it . if you want really loud booming sound that shake the room ? not the system for you . you 'll need to spend more .
