Which direction should your subwoofer face?

Setting up your dream audio system or surround sound setup is no simple task. Whether you’re looking to determine how many surround speakers your living room actually needs, what equipment you should purchase, or where to place your hardware to ensure you have the most immersive audio possible in your space. Your subwoofer is a key component, providing bass sound that can make spaceships, marching dinosaurs, and wild car chases feel even more real.

There are different ways to configure a subwoofer to get the most out of its sound. Generally speaking, most subwoofers are designed to transmit omnidirectional sound, emitting low-frequency vibrations in all directions. With this in mind, you generally don’t need to point the subwoofers themselves in a specific direction, since the bass radiates from the speaker cone. As a result, you can generally face a subwoofer in any direction, as long as you leave about four inches of space between the subwoofer and other surfaces to minimize the amount of reflected sound.

What matters most when trying to get the best sound from your subwoofer is where it is placed, rather than which direction it is facing. For this reason, the best way to choose where to place your subwoofer is to test its sound in your room to get a feel for the characteristics of the space. Start by placing your subwoofer where you usually sit and move around your room to find the places where the bass sounds loudest. These locations can be other options for placing the subwoofer instead.

If you have multiple subwoofers, you naturally have a few more options for where to place them and which direction to point them. When working with a dual subwoofer setup, you don’t need to place both subwoofers in roughly the same location or direction to get the best bass possible. In fact, they may have minimum distances that you need to keep from each other for optimal sound. Also, wherever you place them, remember to make sure they are both at least a few inches away from any other surface.

Just like with a single subwoofer, multiple subwoofers working together will sound different depending on the characteristics of your room. What sounds best in your living room may sound terrible on an outdoor patio.

There are different placement approaches that tend to work well in a variety of spaces:

• In the front corners of the room, facing where you might sit.
• On the inside of each enclosure.
• Also arrange them on opposite sides of the room, in front of the sofa.
• On opposite diagonal corners facing the farthest walls.

Audio device maker SVS says you’ll likely get the best sound with the opposite corner arrangement or by placing your subwoofers so they face each other in the middle of your room. Your exact results may also vary depending on your environment.

Installing a subwoofer is one of the best ways to upgrade your car’s audio system. But if you mount it anywhere and without much consideration, you won’t be doing yourself or your audio setup any favors. The interior of your car is an unusual environment, with many competing elements when it comes to sound. It’s a small space, but it has many different surfaces that can reflect or absorb vibrations coming from your speakers and subwoofer. There’s also road noise coming from outside, and this can be different depending on the weather and also where you’re driving, like a winding country road, bumper-to-bumper traffic, or a fast highway.

Most car subwoofers are mounted either in the trunk or under the seats. Aside from that, your subwoofer can also point toward the roof, face the rear, or be angled toward the windshield. Which direction you choose depends a bit on your taste and the type of car you drive, but the most common position is usually to have the subwoofer facing rearward. Indeed, it’s an effective way of making the most of your car’s dimensions, sending vibrations towards the boot before they bounce through the rest of the car to reach you. In turn, it makes the most of your car’s cabin, where sound wave reflections can gather and sound even louder. The amount of space needed for low frequencies to bounce around can also give the waves time to develop before reaching you, making those low frequencies sound softer than they would over a shorter distance.
