Bluetooth­-enabled soundbar with a powerful, 200-watt wireless subwoofer.

The difference between merely watching a movie at home and being fully immersed in a cinema experience is JBL® sound. The JBL Cinema SB400 includes a two-channel soundbar for high-definition audio that complements your high-def video. It features four 2-1/4-inch (57-millimeter) cone woofers, two 1-inch (25-millimeter) dome tweeters, an amplifier that offers up to 120 watts of power, three HDMI® inputs (for multiple sources such as your cable box, DVD player, videogame console and computer), integrated Bluetooth® technology (ideal for streaming music from digital devices), dual-position equalization (which optimizes sound based on the soundbar’s location) and HARMAN Display Surround technology (which creates a surround-sound experience from only two channels). And for people who want more rumble and realism, the SB400 includes a separate, 200-watt, 8-inch (400-millimeter) wireless subwoofer with bass-boost functionality, which lets you tailor low-frequency response. Designed to complement flat-panel TVs that are 46 inches (1.168 meters) and larger, the glossy Cinema SB400 is ready to work with any type of A/V format and deliver the great JBL sound that you’ve come to love – and look great doing so.

Rated 5 out of 5 by from GREAT SOUND BAR I shopped all brands and price ranges of sound bars and the SB400 is the top of the list. Most sound bars either give good vocals or bass but not both. The SB400 fills both of those areas perfectly. I just set up my SB400 Refurb and couldn't be happier. Crystal clear vocals, very responsive bass. Pared with my tv volume control easily. Only disappointment is that the on-screen display doesn't work with my tv, but small issue to have such a nice system.

Hello have a new SB400 Soundbar with sub. It will not connect with the sub. I have attempted to reset it by pushing the - volume button and surrond together to reset it does nothing. Lights don't flash or anything to indicate it has reset. ?????

Asked by: Acejhorn
If you cannot pair the soundbar center speaker with the subwoofer, please ensure that both blue LEDs must flash quickly, one on the center speaker, one on the subwoofer. If just one of these LEDs does not flash quickly, pairing cannot take place. If it is difficult to make one of the LEDs change to quick flash, it may be that the pairing button is held too long, or not pressed in the right angle. Try again with a short, firm press less then a second.

Is there a way to lock Bluetooth connection?  I live in an apartment and I don't want any joker trying to connect to Bluetooth. 

Asked by: vmci
I would recommend that you reset the SB400, removing all Bluetooth devices from it, and then pair your own device (smartphone) to it, so that other devices can't be paired to it. This will stop this from happening in the future. To RESET: In standby mode - Press "Volume-" (minus) button and "Surround mode" button simultaneously for approx 3 seconds - soundbar turns on - soundbar is reset. It is important not to press too hard on the Volume- button, because that will also press down the Volume+ end of the button, and the reset will not work. If you press too hard, two clicks should be felt or heard, indicating you have pressed to hard.

Can I add speakers (not subwoofer) to my JBL 400?

Asked by: Derrick
The SB400, and all of our soundbars, are stand-alone systems. You cannot add any additional speakers to this speaker.
