I buy two of these unit . brand new . one of they arrive DOA . there be no indication anywhere of any packing damage and everything appear brand new in physical appearance . obviously , not the end of the world , as Amazon will send a new one and\/or refund you , but RCA should not be release doa brand new product , even if they be at rock bottom price ! the unit that be work , so far , seem nice . the speaker be indeed tiny , but the cable be nice and long , and produce a good surround effect . the input be only stereo -lrb- eg just leave and right -rrb- , but personally that be all I need . it come with a remote which can adjust the volume to specific pair of speaker -lrb- eg front pair , rear pair , center speaker , subwoofer -rrb- - this be very useful for calibrate a room .
