    Customers like the sound quality of the speakers. They say it has a bass boost to enrich the sound, the bass that comes out of the subwoofer is incredible, and the sound is clear. They also say the external speaker is clearer and does not buzz like the TV. The mode is good for late night listening with the sound turned down so that others are not bothered by the sound. The included subwoof and independent subwoofar volume make the sound bar virtually invisible as a sound source.

    Great quality and a very crisp sound
    5 Stars
    Great quality and a very crisp sound
    I was skeptical seeing a Polk soundbar being priced so low, but I’m happy I ended up purchasing it. I toggle between the 3 voice adjustments depending on what I’m watching. I saw comments on the remote, so set it up to where it is controlled with my Apple TV remote automatically. I still use the original remote for voice adjustments and I haven’t experienced any issues with it
