GoKawiilSubwoofer placement, not facing direction, determines bass quality
Audio guidance clarifies that most subwoofers are nearly omnidirectional because bass frequencies spread as long, powerful waves rather than beaming like tweeters or midrange speakers. As a result, which way a subwoofer physically faces has little effect on sound quality compared to where it sits in the room. The main exception is ported subwoofers, which need clear space around their vents to perform properly.
