What can I use instead of a Vizio subwoofer?

You can get a used AV receiver. The ones without HDMI are pretty cheap and will have digital inputs and subwoofer out. Even a pair of cheap speakers will sound better than the soundbar. James, did you ever solve your problem? I have a Vizio wireless sub for a 3821 sound bar that just stopped working.

Why is my Vizio subwoofer not working with my sound bar?

When your wireless VIZIO subwoofer won’t connect or pair with your soundbar you’ll need to take the following steps to fix it… especially if you’re not in the market for a new sound system just yet.

Where are the rear speakers on Vizio 5.1?

VIZIO 5.1 Sound Bar’s include the center speaker in the center of the sound bar. These are the rear left and the rear right speakers that in our sound bar systems connect to the subwoofer.

Can a subwoofer be connected to a different sound bar?

No, you can not use a different subwoofer connected to a soundbar of a different branded system, especially without a technical expertise. The only case this is possible is if are a sound specialist or have the soundbar bluetooth connect a matching wireless transmitter to plug into the sub out of the soundbar. (source)

How can I tell if my Vizio sound bar is on?

To ensure the soundbar is powered on, try turning the volume up and down, if the sound bar is on, the volume indicator lights will appear. The subwoofer has a power switch. When powered on a light should appear near the switch.

Make sure the subwoofer is powered on. (A light on the back of the subwoofer will light up to indicate the subwoofer is powered on.) Try re-pairing the subwoofer. For instructions on how to pair your subwoofer to your sound bar, consult your models Quick Start Guide or Installation Guide.
