5. Second subwoofer
A subwoofer is probably the most important speaker in a home theater system (well, maybe the center channel is more important), so why settle for just one? Bass can be a tricky beast. Depending on where you set up your subs, you can have multiple boom and dead spots in the same room because sound waves wash around the room and get into fights with each other. Adding a second sub helps balance the bass and reduces dead zones so every seat in the room gets the same punch in the chest.
Sunfire Atmos and Velodyne MicroVee subwoofers.
Adding a second subwoofer isn’t hard. Because the bass channel (the .1) is mono, you can use a Y splitter on the subwoofer output of your receiver. Manufacturers like Velodyne include room correction software to adjust the subwoofer to your room. Sunfire’s new Atmos subwoofer includes a throughput so you can add a sub by just tethering two of them together.
