UPDATE:-
Received the T670 Sound bar on Monday. Installation was done yesterday by Samsung team. Connection with wireless rear surround speakers works very well. Setup looks clean in my parents room. Now coming to sound quality compared to previous sound bar(F450 Samsung). Sound is more clear without overpowering bass. Bass is punchy but subtle(better than q60t i tested in showroom). I tested the sound by playing several 5.1 movies on Netflix and prime. You get the surround feeling like in cinema. But one thing that is bothering me a bit. When I play these 5.1 movies on OTT, the vocals are sounding low. Not sure why. I've tempered with settings like increasing the treble, decreasing the bass, changing sound modes (only game mode has bit clear vocals compared to others like surround, Dtx virtual etc.). While playing YouTube, cable etc. the vocals come through rear speakers as well so in that scenario vocals get prominent and well balanced. Don't know what could be the reason behind this. I've hooked up this sound bar with tv using an digital optical. Anything I can do to increase the vocals when playing OTT 5.1 Dolby content. Please do share your suggestions on how can I make it better?
Overall for the price I paid i am happy. Also got a free 32inch Samsung tv free with it( have hooked it up in my office).
Have a great day. Cheers!
