A:AnswerThis model does not pair with a wireless subwoofer (natively.) There are adapters that allow you to pair with wireless subwoofers (Rockfish comes to mind.)
A:AnswerYes, this will work with any TV that has optical, 3.5mm or RCA outputs. In addition, this has Bluetooth to allow your phone or mp3 device to pair with it for sound.
A:AnswerIt should be compatible with any TV that has either an AUX 3.5mm out, RCA out (the red/white component connection) or digital optical (highly recommend this connection for best sound quality). I used this on my SOny X850C and it worked fine, but to save you the headache I found, my TV would NOT allow the sound of navigating the home menu apps through the soundbar, only the TV speakers. This was troublesome because when I connected it properly, even set the audio settings to use Audio system instead of my TV speakers, it would play the notification sounds of navigating apps on my Android TV OS through the TV speakers leading me to believe it wasn't working. It worked when I was out of that home screen, but had to find that after a lot of digging up being too presumptuous that it wasn't working immediately.
A:AnswerI have this sound bar hooked up to my Insignia tv which is also a 40 inch. Everything works great and the bar does not interfere at all with the power button or any function of the remote.
