Surely great for movies. We reduced going to a theatre as the sound effects are better with these compared to some theatres.
My room is around 3m x 3.5m (Considering the viewing area alone)
Pros:
1. Thundering Bass. My Sofa literally trembles.
2. Excellent Surround (ambience) sounds
3. 4K HDR Passthrough
4. Wireless - Extremely convinient
5. Individual control for Surround and Bass
Cons:
1. No Dynamic range compression except with DTS
2. No separate control for Mids and it could have been slightly better for sure
3. Interference with 5Ghz Wifi in some channels
4. Surrounds have to be charged
