when i first hook it up and test it , it sound a little weak , but i go through the menu and everything be turn down , like the volume for the speaker and subwoofer , once i put it up the sound be amazing , the bass come from the woofer seem like a 100 watt system rather than a 70 . i reccommend this for any room small or large , you will not be dissapointed especially at this price .
