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 Love this sound bar. Great sound looked at lots of different sound bars and found the quality on this one to be great.

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.

Rated 5 out of 5 by from Awesome product Just bought this a week now and got to say it is bad to the bone. Its better than my Samsung 550.

Rated 5 out of 5 by from Technologically experienced and audiophile I've had this for about 6 months now and absolutely love it. Run this with HDMI out of my computer to a samsung 4k and it sounds incredible. Hits lows much better than I was expecting and the bass boost does not distort like others do.

Are the HDMI inputs 2.0 and, therefor, capable of passing 4k video? If not, can you run sound from the TV to the unit?

Asked by: aPlateOfGrapes
The SB400 is not compatible with 4K pass-through. Yes, you can run sound from the TV to the SB400. Simply connect the TV to the SB400 using your choice of either HDMI or optical and make sure that the TV is set to use external speakers.

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.

The remote for the soundbar doesn't work unless I'm in a select spot directly in front of the speaker. Is this normal for anyone or is mine messed up? I have to get up every time I want to change the volume. Might as well not even have a remote.

Asked by: Vmadams
What you are experiencing is not normal. First thing we have to make sure of is that there is nothing in between the remote and the Cinema SB400 that can cause interference with the IR signal your remote is sending to the soundbar and that you have fresh batteries on your remote. If the issue occurs after making sure that there is no interference, complete a reset on the soundbar by following the steps below and retry the learning feature programming. In standby mode - Press "Volume-" (minus) button and "Surround mode" button simultaneously for approx 3 seconds - soundbar turns on - soundbar is reset. If you are still having issues, please submit a case at jbl.com/contactus and our Customer Service Team will be glad to assist you.

I have a jbl xtreme but I wanted something stationary at home .Is this a good speaker for music ?

Asked by: Emilio
The Cinema SB 400 is mainly designed to replace your TV speakers and also has the ability wirelessly stream audio from your smart devices, delivering room-filling, full-range sound reproduction with exceptional bass. This should be a suitable stationary system for your home.

I turned my SB400 system on but I am not getting any sound from the system, tried the Bluetooth, checked my tv connection to the system, system not muted.

Asked by: Rlgr
What you are experiencing with the SB400 is not normal. Since you've already tried different sources and checked if the system is muted, it does look like your SB400 has developed a fault. Please try to complete a reset to try and fix the issue. In standby mode - Press "Volume-" (minus) button and "Surround mode" button simultaneously for approx 3 seconds - soundbar turns on - soundbar is reset. If you are still having issues, please submit a case at jbl.com/contactus and our Customer Service Team will be glad to assist you.
