How to Mount a Subwoofer Under a Couch

Get some bass in your couch by adding a subwoofer.

Are you looking for the ultimate low-frequency rumble in your home theater system? If so, take it to the extreme and mount a subwoofer under your couch. This will direct low-frequency sound waves right into your furniture, and provide you with a truly immersive experience when you're watching a movie or listening to music.

Things You'll Need

• Utility knife
• Tape measure
• 3/4-inch plywood
• Jig saw
• Subwoofer
• Wood screws
• Screwdriver

Instructions

1. Turn your couch over so the bottom side is up. Cut away the fabric from the underneath of the couch where you plan on mounting the subwoofer. On some couches, you may be able to remove the fabric by taking out staples.

2. Measure the wooden framework underneath the couch. Each segment of the couch will have a square wooden frame underneath it. You'll be cutting a piece of wood that will attach to the four edges of this frame, filling in the space with a panel that will hold the subwoofer.

3. Cut a piece of 3/4-inch plywood to match the dimensions you took in the previous step. Cut an opening for your subwoofer in the center of this piece of wood. Place the subwoofer into the panel and attach it with wood screws placed in the holes in the subwoofer's mounting ring.

4. Place the panel with the subwoofer onto the bottom of the couch, with the magnet of the subwoofer extending below the couch, and attach it to the square wooden frame on all four sides with wood screws spaced every 3 inches around the perimeter. Turn the couch back over to use it.
