A:AnswerI would keep the JBL sound bar unless you upgrade to Martin Logan or a super high end sound system. Polk and JBL are great just as well. The high end Samsung sound bars do sound good but no reason to switch
A:AnswerUse the button on the remote to turn down the woofer, that's where all the bass comes from. I run mine around -2 for vocal movies, and around +2 for action movies. Also toggle the different surround modes to see if one does better for vocals.
A:AnswerI have this soundbar over 6 month. My advice for you - buy it. Sound wonderfull, bass on +6 (glass collection under the soundbar on shelfs start shaking), very easy to connect to my phone(Bluetooth). Worth every penny. Don't think - BUY IT!
