For a 3.1.2 system, it is a very impressive sound bar. The quality is top notch. Once you get it calibrated, this system produces very good surround sound. For those wondering about the sub, it is very capable of producing very good LFE. Much more deeper than the Yamaha (Ysp-2700) I too was wondering if I could get good surround with a 3.1.2 system and it proved very satisfying. The key is good calibration. It took me 3 tries to get it right. Its important that you set the mic at ear level and seating distance. Finally decided to use a tripod and that worked to perfection. MAD MAX ATMOS was excellent. TRANSFORMERS AGE OF EXTINCTION ATMOS was a great test because of all the effects and rumblings in the movie. Again, this unit handled it with no problems. My last test was SUICIDE SQUAD and again, great audio. This system can get really loud. Calibration is key for this system. Will see how this system fairs with gaming. Below is a picture to give an idea of the size of the unit. Tv is an lg Oled 65"
