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 Awsome Sound Bar and Subwoofer! I bought this about 6 months ago and compared to my old sorround sound system that i had its so much cleaner and the bass is ridiculous and being bluetooth is so awsome and not having wires run through my walls and having to make holes. Its so easy to setup to your tv or even if your just using it in the garage to play misic!

Rated 5 out of 5 by from Awesome Sound I am enjoying putting this system on when I watch movies or play games. My daughter is able to enjoy it as well as it doesn't blast her out of the room but it makes her feel like she's at the theater

Rated 5 out of 5 by from it's simply awesome My house is small and my surround system was finely giving me trouble after all these years so I needed to do something. I decided to give this soundbar and sub a try despite some not so great reviews. I started off having some issues with my wifi once I hooked everything up and realized I was running too may things on a 2.4 frequency but since I have a duel frequency router, I moved everything I could to the 5 and no more issues. The sound is crisp and clear and I have no problems with the connection to the sub but believe I would have if I kept everything on 2.4. I'm thrilled that it has Bluetooth and so many HDMI connections so I have more options. JBL has never let me down in quality and value and this soundbar is no exception. Over all, just a few adjustments for me and my world is full of ear pleasing sound and worth every bit of the effort and purchase price.

I am really missing a button on the remote to select a bluetooth source. 1. Is there another way to let the soundbar switch to bluetooth, without having to walk over to the sounbar? 2. Could I program a universal remote to select a bluetooth source?

Asked by: Dwight
Sorry to hear that, for the first question, sadly, no. You have to manually press the Bluetooth button. For the 2nd question, although the SB 400 can learn other TV remote's command, it can only learn Power on/off, Volume +/- and mute.

SB400 Subwoofer without soundbar.  Can you have it alone, how if so?  Even know I'm pretty sure it can't, I ain't an expert.  Hope it might.

Asked by: gmh2
Unfortunately, the SUB would need the SB400 for it to work. It is not a stand alone type of Sub Woofer. So no, you cannot use it alone.

I'd like to ask you about the intern wifi frequency of this device 2,4 GHZ or 5 GHZ? I bought this product and it shows instability problems. Sometimes immediately stop working  although every status display is OK.  After a while it works again. Any idea?

Asked by: Andras
The SB400’s Bluetooth is running on 2.4 GHz. If you are having intermittent connection issues when connected via Bluetooth, this can be caused by any electronic device between the source and the soundbar that is also using that frequency. Please try to eliminate any source of electro-magnetic interference.

My sound bar has lost it's sound. It has worked well for over a year?

Asked by: runman
What you are experiencing is not normal. To isolate if the issue is with the SB400, there are a few things to check – • Make sure that the cables from the TV to the Soundbar are snugly connected. • Check if the TV is set to use external speakers. • Check if you are on the correct source in the Soundbar in respect to what cable you are using. • Press the “Volume +” button on the Soundbar or on the remote to make sure that it is not on Mute. • Try a different cable, and a different port on the TV, if available If what was suggested did not help, please submit a request at www.jbl.com/contactus and the Customer Service team will be more than happy to further assist you.

Is the SB400 compatible with any other JBL wireless speakers that can be added to expand it from a 2.1 to a 5.1 system?

Asked by: MikeJB
The SB400 is a pseudo surround system which means it is a stand alone system and no other speakers/add-on's can be connected to it.
