What people are saying

Rated 4 out of 5 by from very good if you know what your doing i have had this sound bar over a year now and love it. i noticed tho that the rear speakers looks connection with the sound bar then after a 30 seconds or so they come back on. it is a pain but hey it corrects its self. another note this bar actually does work in a very large room i have mine in my basement and its still sounds amazing. one this i dislike is that there is no option for custom EQ settings like bass mid high there is only sub rear speaker volume and tone. overall really good product.

Rated 1 out of 5 by from Not happy at all. I just purchased this product like a few days ago. Right away the rear speakers keep going in and out. Now reading the reviews it’s a problem many are having. So I’m returning for a different brand

Every time I move the cord on the sound bar Slm4r it cuts of sound bar as if there is a short in the power cord.

Asked by: Darrel22222
The cord may be faulty or it may have a faulty connection which causes the LG SLM4R 420W Sound Bar w/ Bluetooth Streaming and Surround Sound Speakers to cut out when you move it. You will need to have the unit inspected by an LG Authorized Service Center if there is one in your area. You can visit our site at https://www.lg.com/us/support/find-service-center to see if there are any LG Authorized Service Centers near you or you can contact our Support Center at (800) 243-0000 for assistance...^IFV

This does not have HDMI ARC, so the TV wont turn this on automatically correct?

Asked by: yeko
That is incorrect. If the HDMI ports on your TV are HDMI-CEC compliant then your TV will automatically turn the LG SLM4R 420W Sound Bar w/ Bluetooth Streaming and Surround Sound Speakers on if you activate HDMI-CEC in the TV's menu settings. Different TV manufacturer's package HDMI-CEC under different names so check your TV's owner's manual to see what name HDMI-CEC is packaged as. On LG TV's, it is packaged as LG Simplink...^IFV
