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 Stellar sound quality Bought the SB400 a few weeks ago. Sound quality is superb, subwoofer makes it sound like I'm in a theater. Used for TV, movies, and music and I am never disappointed. Looks great in front of my 65" And the wireless sub allows more freedom in placement.

Where can I find a copy of the warranty?

Asked by: Hawkeye62
There is a warranty card included in the box of the SB 400. Basically, you do have a one-year warranty from the date of purchase that protects you from manufacturing defects.

I have the sb400 subwoofer, but have broken the sound bar..... Will any blue tooth sound bar work with subwoofer.

Asked by: Wayneukboy
Unfortunately, no. It will only connect to another SB 400 soundbar. As for the broken soundbar, please submit a case request at www.jbl.com/support-contact.html for further investigation.

I have a new Samsung 60" 4K TV (un60k8000fxza) and have hooked up the SB400 sound bar via HDMI (arc). The sound bar sometimes turns on with the TV and other times does not? Also on screen information display does not work?

Asked by: drm3826
It seems like a cable issue where the HDMI cable is not providing a solid connection between the TV and the speaker. Try replacing the HDMI cable to isolate the issue. As for the OSD, this is because, when watching TV, the TV set cannot at the same time show, or blend in, OSD information from the soundbar. This is because the TV shows a signal sourced from its own, internal tuner, and not from the soundbar. The TV can only show OSD info when the soundbar is selected as the source.​ If you have other questions or concerns regarding our products, please submit a case request at www.jbl.com/support-contact.html and the Customer Service team will be more than happy to assist you.

we have had our JBL SB400 for almost two years and over the past 7-8 months we are hearing a very loud pop or crack. Sometimes it is so loud it knocks out the sound and we have to restart everything. VERY FRUSTRATING!!

Asked by: Shellsn1
Please try connecting a different source (phone, different TV, etc.) to the SB400 and see if the problem persists. If it does, please submit a case at jbl.com/contactus and our Customer Service Team will be glad to assist you.
