This article provides an overview of connecting multiple subwoofers in a home theater setup.

Just because you have a subwoofer in a home theater setup doesn’t mean you’ll get the bass impact you need or want. If you have a large or irregularly shaped room, or if you have acoustic issues, you may need more than one subwoofer.

Subwoofers deliver that overwhelming low frequency impact that every solid home theater system needs. They deliver the energetic explosions in sci-fi and action movies and the oomph of bass and kick drums in music.

Before adding a second subwoofer, you should perform some basic room placement and bass management settings to ensure you're getting the best performance from the subwoofer you already have.
