Fixing a disconnected Samsung HW-F450 Wireless Subwoofer

I had a hard time of fruitless Googling trying to find how to fix my subwoofer. Turns out it’s very easy. Here you go. You’re welcome.

In case the URL goes bad one day, turn off the sound bar, plug in the subwoofer, stick a paperclip into the “ID Set” hole on the subwoofer and hold for five seconds,  then press the mute button on the remote for five seconds, then power up the sound bar.

  1. is there anyway to do it if you don’t have a remote? my remote was lost and my girlfriend moved something. Now my sub woofer is not working.

    1. There is a way to reconnect. Mine never reconnect and I have to do it everyday. Annoying. I think there is a problem with mine. This is the process.

      1. Turn the soundbar off.
      2. Insert a straightened paper clip through the reset hole (behind below the label)
      3. Notice the blue led blinking rapidly.
      4. Now turn on the soundbar. It should reconnect.

  2. This did the trick for me too, thanks for putting this fix out there! Had this at least 5 years now and still going strong , and it’s been dropped by cats and children. Durable product for the money .


    The Subwoofer’s linking ID is preset at the factory and the main unit and subwoofer should link (connect
    Wirelessly) automatically when the main unit is turned on. If the link indicator (, _b) does not light when the main unit and subwoofer are turned on, please set the ID by following the procedure below.

    1. Plug the power cords of the main unit and subwoofer into an AC wall outlet.
    2. Press the ID SET button on the back of the subwoofer with a small, pointed object for 5 seconds.
    The STANDBY indicator is turned off and the LINK indicator (Blue LED) blinks quickly.

    ID SET
    While the main unit is powered off (STANDBY mode),
    Press MUTE on the remote control for 5 seconds.

    The ID SET message appears on the main unit’s VFD display.

    To finalize the link, turn the main unit’s power on while the
    Subwoofer’s Blue LED blinks.

    The main unit and the subwoofer are now linked (connected).

    The Link indicator (blue LED) on the subwoofer is turned on.
    You can enjoy better sound from the wireless subwoofer by
    Selecting the sound effect. (See page 19)

    1. Thank You Horice!
      I was on the verge of blowing a head gasket and your info has saved my Brides eardrums!
      And for that she thanks you!!

  4. Thank You Thank you
    After a flustrated husband who even he hid the subwoofer cord so I would not mess with it my first day off of work he’s at his job I did what you said it works!!! Thanks 😁😀😁😀

  5. Perfect. Blue light blinks. Sound bar is OFF, press MUTE on remote. I’D Set appears on sound bar, even tho it’s OFF.
    Turn ON the sound bar. Blue light now is ON steady in a few moments…linked and working.

  6. This fix worked! Thank you! (these are so old, they don’t even show up when you search Samsung’s site!)

  7. I kept pressing the mute AFTER I turned the sound bar on. Your page helped me realize my error, meaning press the mute with the bar off and subwoofer blinking blue.

    Thanks so much!!!!

  8. Very grateful for this info. Worked a treat. Subwoofer was dropping intermittently and bugging me like crazy. Having reconnected with the above process is stable again now.

    First issue in nine years, solid bit of kit, glad I was able to get a bit more life out of it.
    I’ve written the instructions on a piece of paper and taped it to the back of the woofer now.
    Many thanks 👍👍
