What People Are Saying

Rated 5 out of 5 by from EARTH SHATTERING BASS!Crystal clear top end. OK... So having both read and watched hundreds of reviews and videos about this system, I'm well aware that it's not regarded as the best system available especially at its price. However,I just want to share my thoughts on this soundbar for anyone considering purchasing it. So I got a substantial discount,a quarter of the asking price was knocked off making it much more competitively priced. I also have an LG OLED 55"4k SHD Dolby Vision TV and I found that other bars didn't work with my TVs remote control meaning yet another one!, which I didn't want, so knowing these two worked well together factored strongly. Now to the nitty-gritty... The bar is beautifully designed with a stylish retro feel to it in a dark silver/grey finish. It's a hefty wieght and the longest bar I've seen at 120 cms in length. It's also quite deep at 15 cms and 5 cms high and the only bar I've seen with a scrolling led display informing you of settings etc. So the sound?... With every single sound system I've ever purchased, I'm constantly left wanting in the bass dept,craving more oomph and rumble and richness.Maybe it stems from my years as a DJ with 2,000 watt amps driving 5,000 watt PA speaker systems, but I can now honestly say that my search for that earth rumbling bass is finally over. The bass this sub gives out is incredible and thank goodness LG gave the ability to reduce the subs bass by a whopping minus 15! But when I crank it up, even with the subs bass knocked down to - 15 it's still wall shaking. To get around this i activate the night mode which knocks the bass off drastically and I then introduce some bass back by putting the sub at minus 9 or 10 which won't alienate the neighbours lol. You can also up the treble and bass output of the bar from a minus to plus 6.The top end is sweet and clear and my favourite sound processor is bass blast, with movie, music and adaptive sound control being the others. My main use for this is to play house music through and I'm looking for all my old favourites to hear through it. The Bluetooth is excellent, never drops out and works perfectly with both my TV and smart phone. My house is an advert for LG lol. 3 LG TVs,2 LG sj9 soundbars{my father has one too} LG washer, smart phone,4kblueray DVD player, the list goes on. However, I absolutely love this sound system. It's incredible watching transformers or mission impossible through it,it's so intense and immersive that it truly raises my heartbeat feeling like I'm actually in the movie! the soundtrack comes to life through the Sj9. I've downloaded the app and streamed music through it via chrome cast and with "auto on" enabled I don't even have to turn the bar on, I just use my remote to switch the TV on and the bar turns itself on greeting me with a hello and automatically pairs with my TV,and the volume and mute functions on my TV remote operate the bar. It's a quality piece of engineering and when playing back high quality audio on animal programs, my cats are all over it as my picture shows, trying to work out where the tweeting birds are coming from! However, I just have to come back to that sub and it's incredible bass. I'm blown away at how effortlessly it provides such earth rumbling bass that you can feel in your chest and tummy and I marvel at it every time I hear it. I've only had this system on number 26 which resulted in my neighbour at my door asking me to turn it down! Luckily we are great friends and I explained I had a new speaker system and was just opening it up and won't happen again.... It goes up to a hundred, I can't imagine it at that. A 2 year gurantee brings peace of mind and I for one am extremely happy with it. I look forward to coming downstairs and turning it on its so good! Well done lg, a sexy looking and sounding speaker system with endless capabilities. It's a pleasure just watching the news through this bar!

Rated 5 out of 5 by from Excellent I've been using the LG SJ9 Soundbar as my main sourse of A/V in my living room and I am absolutely blown away by the performance of this unit. Its extremely easy to use and the setup is very simple. It had absolutely no issues with compatibitity with other devices. I have my 4K Apple TV passing through it straight into a Samsung 65" UHD TV and everything looks and sounds absolutely fantastic. I controll I/O, Volume and functions throug Apple TV remote and its awesome that the LG SJ9 supports this. My bluetooth devices like iPhone, iPad, iMac connects instantly on demand. The sound performance of the SJ9 is mind blowingly good, I've streamed a few 4K movies with Dolby Atmos and its an absolutely great audio experience! I HIGHLY reccomend this soundbar if you are looking for a full features quality audio powerhouse. Its also a beutifully designed product that looks and feel like a high end product.
