Product Q&A
My soundbar is not playing the first 1-2 seconds of audio from a source. When starting movies/videos the audio does not start until 1-2 seconds after the video, but is in sync. Also, when using devices that have menu click sounds, these are not heard.
What are the similarities and differences between this model and the SB 400. They are the same price--is there any reason not to get this one if I do not have a 4K TV?
Hi, would you like to know the size of the subwoofer (height, width and depth) please?
Do I have to switch from HDMI source to optical every time I play usb connected devices on tv
Where can I find replacement feet for the SB 450?
You have an app that connects to sound bar to know the exact power and directions ?
Is my ARC port broken? When i plug my Fire Tv and Cable box into my Samsung One Connect and use the ARC to the soundbars ARC, i get no sound. Those same devices into the soundbar, sound works.
How many drivers does the sb450 sound bar have in the sound bar itself not including the sub woofer?
