Can you use a different samsung wireless sub with another Samsung soundbar

Question edited for a lot more clarity.
Question moved to a Samsung Sound Bar category.

It is wireless and uses a non proprietary system according to this, so No.

Sound drops out from the wireless subwoofer. The sound on your wireless subwoofer can drop out if there is interference or a physical obstruction between the soundbar and subwoofer. Make sure the subwoofer is within range of a good signal of your soundbar, and that the issue is not with the source audio.

Question about new Samsung HW-F450 setu

try pressing and holding the play/pause button on the remote. This should reset the unit and turn off demo mode.

Check the speaker of the sub=woofer. If found OK, check and replace the damaged component/s at its audio output section circuit. Contact any service technician. Electro help

Because your TV is not Bluetooth-enabled and you are trying to connect it to a Bluetooth-enabled soundbar via Bluetooth. There are other ways to connect your TV to the soundbar:

1. analog AUDIO OUT (L/R) of your TV to the AUX IN on the soundbar (use a 3.5 mm.-to-RCA audio cable).
2. Optical OUT on your TV to Optical IN on the soundbar.
3. HDMI port to HDMI port (this may not work if your TV is not ARC compliant you have to try).

You get better sound quality with option 2.or 3. (if this one works for your TV)

I presume you need link the Wireless Subwoofer to tour Soundbar.
Here are instructions:
How To Link The Wireless Subwoofer To Your Soundbar HW Models Samsung

turn the soundbar off, then press and hold the reset button on the back of the subwoofer until the blue light starts blinking fast. the point the remote at the soundbar and hold the mute button until"ID SET" shows on the display. Then turn on the soundbar and it should find the sub and pair with it.

It is not latching on to the soundbar transmitter. Is the locked light on the device turning on.
Wireless devices are sometimes known to drift. Is the sub silent when the soundbar power is off ?. Even then if its making this sound, the subwoofer amplifier is oscillating at very low frequency. You will need professional help and needs to be repaired.
