    Sound quality is good considering the price points. Wireless subwoofer and rear satellite speakers work flawlessly. Bass is good as well. I recommend purchasing a set of speaker stands for the rear satellites.

    Great set of speakers... A couple flaws

    The speakers are great. Set up is super easy. The set comes with all of the possible cables and mounts which is awesome. My main issue is that the ends of the plugs for the satellite speakers are too big to fit inside my speaker mounts. So I can't route the satellite speakers cables through the speaker stand which is a bummer.

    An easy solution to get decent sound from your TV that, with HDMI pass-through controls, can be controlled like your native TV's volume. No need to mess around with handshaking or compatibility; this will take up an HDMI port, but then becomes a native extension of your TV. The TV then manages your inputs (PS4, Xbox, etc).

    I bought this to replace a 10 year old system. The dialog was almost impossible to hear over background noise. It took several days to get the sound close to where we wanted it. The center volume really does pull out the dialog. I have yet to find that "mellow blending" of music using the Bluetooth with my iPhone
