How Do You Update a Soundbar Firmware?

If you want to upgrade the firmware on your soundbar while it is linked to an audio/video receiver (AVR), you must do it through the AVR. To find out if your AVR has a firmware update capability and how to apply it, follow the owner’s manual. If your soundbar isn’t connected to an AVR and doesn’t have an Ethernet port, it probably can’t be upgraded. 

 If that’s the case, the soundbar’s website may have a firmware upgrade available in such situations. But you will need to follow these steps to complete the process.

Step-by-Step Instruction

  1. Download the latest software from the website. 
  1. You will find a JBL Bar 9.1 bin file after unzipping it.
  1. Make a blank USB flash drive, create a new folder in the root directory called “UPG”, and copy the bin file into the newly created UPG folder.
  1. Then carefully attach the two separate speakers to the main soundbar.
  1. To begin the software update, please put the USB flash drive into the Soundbar’s USB port on the back panel and long press the Power and Volume buttons on the Soundbar for 10 seconds.
  1. On the Soundbar’s front display, you’ll now see “UPDATING” appearing. This means the update is in progress and you’ll be able to see when it’s complete.
  1. Please wait for the software upgrade to be completed. After the device has been rebooted, it will be in standby mode.
  1. The soundbar’s firmware must be updated to the most recent version after a successful upgrade. You can now check the software version by following the above-mentioned steps.


  • Your soundbar’s software will update automatically when it’s not in use during the night if it’s online.
  • JBL Bar 9.1 China version won’t work with this software upgrade.

Can You Add Speakers to the JBL 9.1 Soundbar?

A wonderful method to enhance the audio in your home theater is the JBL 9.1 soundbar. Can you, however, put external speakers on it? The JBL 9.1 soundbar can accept external speaker connections. Therefore, the answer is yes. You can put external speakers on the soundbar, which will greatly enhance the audio quality.

There are a few things you should be aware of first, though. At First, there are only two audio output connections on the JBL 9.1 soundbar: an optical port and a 3.5mm Aux port. Therefore, you’ll need to use an amplifier or receiver with numerous inputs if you want to connect more speakers than two. 

Second, the JBL 9.1 soundbar’s amplifier can only drive two small speakers or one large speaker at medium volume. Larger speakers or more speakers connected together will probably sound muted or distorted.  Third, the wireless subwoofer on the JBL 9.1 soundbar uses Bluetooth 4.2; thus it cannot be used with earlier Bluetooth versions (3 and below).

Therefore, make sure that your new rear surround speakers have Bluetooth 4.2 or higher if you intend to use them wirelessly with the JBL 9.1. Finally, this soundbar is not the best speaker for music listening because its drivers are set up primarily for TV/movie soundtrack use. Despite this, it can still play music quite fine, although stereo speakers designed for music are better.


I hope this information will be useful if you want to upgrade the firmware on your JBL 9.1 soundbar.
