Where Should You Place Your Sub? 

Where should you put your sub?

If you just bought a new LG subwoofer, it is essential to determine the ideal place to put it. Whatever subwoofer you buy, you should avoid letting it touch the wall. Instead, placing it some inches away from a wall is best.

When you use your subwoofer to play sounds, it will bounce off of your house’s walls. Many experienced people will place their subwoofer below their TV. But, this is not the only area where you should put your sub.

Another good place to put your subwoofer is in your room’s corner, and of course, make sure your subwoofer is some inches away from a wall. 

In that way, your subwoofer will produce more sound and could get the loudest volume out of the LG soundbar.

Don’t leave too much space between your LG soundbar and the subwoofer. It is essential if you use a wireless sub. The reason is that the closer they are, the better the connection.

However, these devices should not be too close to each other. Ideally, make sure the two are at least a few feet apart. Furthermore, ensure there are no devices in between these units if possible.

These devices are connected wirelessly, meaning they utilize the 2.4 GHz band. 

So any other units that utilize the same band, such as a baby monitor and cordless home phone, may significantly affect their connection.

Also, you should try placing your subwoofer in various areas in your room until you get the expected sound.
