Size doesn't matter!
I started my Sonos adventure with the beam gen 2 because I've only heard good things about this brand. Installation is very easy using the Sonos application! The sound bar is installed via HDMI ARC on the TV and is directly recognised. The sound coming out of this bar is clean and high quality, and watching films and TV series with it is a real pleasure every time! The only downside I can find is that trueplay is only possible with Apple devices. If you have the budget, go for it with your eyes closed, you'll be pleasantly surprised!
