there be a rather annoying problem regard the a\/v input which I initially think be originally a defect in my particular unit . however , it seem to be a problem with all t-352 model . when the function be set to Audio\/Video , the subwoofer rumble rather annoyingly , even when nothing be plug into the input . if you plug anything into the input , the sound still remain , and the only way to get rid of it be to set the bass volume to 0 . I do not know if it be a problem with the subwoofer or if it be just a feature , but the sound be nice and clear -lrb- with no low rumble -rrb- when play a cd or dvd directly through the unit . if you plan to connect you video game console or computer to these speaker , however , do prepare to be annoy .
