Great little soundbar, $30 more expensive than the Samsung HW-T450 Soundbar and missing the separate sub. But it has far more features e.g. Bluetooth 5, hdmi arc and aux . After owning both I think this is far better.
I have mine on my desk so the built-in subs are more than sufficient and the DTS Virtual:X 3D surround works really well too.
Has an option to add an external sub if needed too.
Had a quick look, this was $159 last year…
