The box I received was large and heavy. This is because the subwoofer is enormous. I placed it next to the TV and the soundbar, which is actually quite modest in size, under my TV.
It's just a matter of connecting a few cables, connecting to Wi-Fi, and it's ready to go. You can also stream music to it via smartphone. Handy and fun when I want to put on some music while doing housework. The sound is unparalleled. Not with headphones, earbuds, or average speakers. The subwoofer vibrates sound waves throughout your body. Music sounds much better, just as it should.
Movie night is what I bought it for, and the Dolby Atmos makes it feel lifelike. The sound comes at you from every direction, and thanks to the strong bass, you can feel it. I find myself watching movies more often than before. I think the sound has improved my experience considerably, and watching movies has become much more enjoyable. Maybe this is the impetus for me to buy a new TV for the ultimate experience.
