I've had this since December 2019. I just plugged it in to use it in my new house and heard a loud crack and saw a flash of light inside the unit. I've never seen a piece of audio equipment do this ever before.

Had to restart everything to get rear speakers to work. Samsung tv and sound bar/bass/rear speakers. Once this was figured out all was fine. They are rear speakers, as such, if dialogue is from front then that is where the sound comes from. They do add atmosphere and rear sound effect if that is the film's 5.1 sound system. You do not get 5.1surround sound from non 5.1 source. Better systems are available but for what cost? JBL 9.1 in living room sounds better but would not be at lower volume in bedroom at night.

I recently upgraded my sound bar to a Samsung HW-N650 which is excellent in itself but found out about these speakers and decided surround sound would be even better. Set up was simple. No need for the included Bluetooth dongle, these pair direct with my sound bar. Positioning the receiver box was easy (for me), just out it to the side of my sofa by the wireless subwoofer behind the sofa. The long wires for the speakers are out of sight behind the speakers, which sit on a shelf behind the sofa. Sound wise, there's very good. Once I had adjusted the volume of the rear speakers I had a perfect balance of surround sound. I watched Tomb Regards on Netflix and the sound was incredible. Immersive sounds that you just don't hear from normal speakers. You really feel like you're in the action. Overall, I'm really impressed with these.
