  • I’m happy

    from Best Buy US on October 2, 2019

    I’m pretty happy with my purchase. This isn’t the loudest subwoofer, but this does a pretty decent job with the low end, and makes my system sound very balanced with what I have. I wish there was a remote to turn the sub on and off. The standby mode hasn’t worked very well for me. It would turn off ok, but has a problem turning itself back on when needed.

  • Seriously?

    from Best Buy US on September 29, 2019

    I bought mine because of brand, features, price, and overall reviews. I set it up, read through the detailed operation instructions, and noticed a surprise. The auto-on/off feature doesn't work for movies! So you have to find the power button low and in the back at the beginning and end of each movie you watch. I returned it and bought a great Klipsch sub.
