Alright, read me out.
The sound bar squeals at certain high frequencies, and for the subwoofer, if the bass has a sizzle/ripple effect (the wubs), then the dust cap is going to shake. Let the subwoofer cool off if the dust cap begins to shake, because the heat impacts the glue.
Overall, I'd still recommend it.
The subwoofer also goes on standby, so you wouldn't have to shut if off from the back after the sound bar goes off.
Movie mode loudens vocals, and Music mode loudens bass and stuff.
You may have to switch between True Volume (TVOL) and Virtual: X (surround sound), for certain sources. Because some songs and performances I've listened to, depending if one is one or the other, or if both are on/off, you may hear the lead singer lower than the back up singers.
Movie mode - Best for vocals.
It sounds great no matter the volume. The bass, it's dominating. The system isn't bass heavy. This small subwoofer can vibrate through multiple rooms. Even on low I could feel the vibrations on the couch.
Be careful with Bluetooth, because if the source is buffering or has low clicks in the stream, the sound bar goes quiet for a quick sec. And the Bluetooth wave and WiFi wave can interfere with each other, basically cutting connection briefly to the system.
For me, my WiFi router is a few shelves below the sound bar, so that cutting would happen if I'm playing something that's increasing the air frequencies in the room.
So if there's cutting in the sound, either switch off the router, change the song, or allow whatever you're streaming to load.
Again, this compact system can really resonate. I'm using it in a closed living room. So for me, sound waves are able to bounce better. So I can comfortably listen to it on low.
Just get it.
It's not ugly.
