    The NB4540 is extremely easy to setup , all you need to do is connect your various devices, place the soundbar in front of your TV and find a convenient location for the subwoofer

Rated 4.6 out of 5 by 199 reviewers.
Rated 5 out of 5 by Great sound bar This was brought to accompany our new TV. Its is great. Really easy to set up and connect. Bass connect through bluetooth. Really improves the quality of the sound on a lower volume level . Like the fact we can connect any device and play our music through it. Kids love it. Have to keep telling them to turn it down. Great value too , being middle of the range. Would defiantly recommend. 10 February 2016
Rated 5 out of 5 by Lovely :) Lovely sound ..lovely product...extremely satisfied. 02 February 2016
Rated 5 out of 5 by Small & Compact Excellent product to sit alongside my LG Oled, purchased this on offer from Currys as an impulse purchase, Previously owned an LG soundbar without problems for several years so no doubts in the brand whatsoever, I feel the sound quality is excellent for watching movies etc, if you want to fill your room with loud music it appears the bass takes over and slightly spoils the sound clarity, however it suits my needs as have 3 children and playing loud music in the evening is off the cards anyway, overall scores excellent on quality and appearance can be wall mounted so numerous options on placement, wireless is also excellent just remember it is wireless but both the sub and bar do need to be close to a power source to function. 29 January 2016
Rated 5 out of 5 by what a difference Bought when we got our LG tv, never had a sound bar before, thought it would be beneficial for our son who has a hearing loss, found it was a big help 29 January 2016
