Fantastic Quality - Setup a little unclear
Once opened and laid all the kit and wiring out, I had to decide the layout for the speakers locations. There is a leaflet that comes in the box that demonstrates the most ideal setup although due to my room layout I changed it for my liking. The main unit has colour coordinated ports with the cabling matching the colours so it's easy to find out which wire connects to. Note - the cables are interchangeable (which is what I did). I have the tall boy speakers at the front either side of the screen with the smaller speakers and central one behind me (central would ideally be in the middle by the screen as voice audio tends to me be prominent in this one). Once setup and the cables tidied up, I immediately paired my phone via Bluetooth to test the new surround sound but noticed that the sound was only coming out of 3 of the 6 speakers (sub woofer and either the tall boys or small ones) depending on how I had wired them. Although when running the audio test, found that noise was coming from all of them so wasn't sure of the issue. After re-wiring for about an hour (labyrinth of a room) the issue was still the same. After looking on forums and not finding any clear help, I turned on my projector (instead of TV) and loaded the Units main menu. Only upon analysing and playing with the remote did I discover that the default mode of the sound system is to play out of half the speakers... (Why??) After a couple of clicks I changed the mode to cinematic which highlights in an image that all the speakers were selected. Connected my phone again and hey presto! The audio quality is awesome and you can change each speakers balance and volume individually to benefit the layout of your room. I've connected it to my Xbox via Optical Cable and can say that both games and movies are far more immersive with the audio. You don't know what good audio is until you've had it! I used to have a sound bar behind me setup similarly but with noise only coming from behind. Completely different experience with noise coming from all around! Highly recommend and suggest you take a read of this if you have setup difficulties - I was a little imaginative with how I wired and laid my lot out. I've not tested the full LG capabilities of this system nor the Blu-Ray player due to it being connected to my Xbox but imagine it's pretty decent!

Great Sound & Connectivity
Bought this as I needed to upgrade from an old DVD all-in-one system. I weighed up going for a full home cinema receiver, but they're generally huge and I'm restricted by space. This sounded like a good option, and so far, it's near perfect for my needs. Set-up was easy. I used most of my existing speaker cables (apart from the LG subwoofer, which is wired and has a bespoke connector). I connected my Sky+ HD box via an optical cable, and bought a new HDMI 2.0 (high speed with Ethernet) cable to connect to the TV from the unit to enable the ARC function. Everything works as I expected - and more! I have a Samsung TV, so I wasn't sure if the SIMPLINK function would work - it does. The LG unit powers on and selects the ARC input automatically when I turn the TV on, and even better - the volume of the unit is then automatically controlled from the TV remote control. Sound is great and well balanced. Bluetooth connectivity is brilliant - connected up my phone and was streaming music from Spotify and Amazon Music in seconds. Also if you download the remote control app, and you've connected the LG to your WiFi network, you can get it to output the sound from the amp to your phone instead so that you can listen on headphones. Blu-ray playback and sound is excellent. The only slight downside that I've found so far is playback of some of my media files from an external USB hard disk - the sound would be fine but the picture playback would sometimes stick a little. Still watchable, but annoying when I noticed it. Note, this was only on some files, so may not affect all. I've gotten around it by connecting the hard disk to a USB port on my TV instead - playback is fine and the full surround sound signals are sent back to the LG unit via the ARC input. Life is good!

Super product with a tragic interface and awful instruction manual
I bought this to replace a Panasonic HT system after buying a LG 4k HD TV. Initially I was HORRIFIED as the unit refused to reproduce 5.1 audio from anything but Bluray discs. Then I realised that the problem is not with the product, but with the loons who designed it! It actually defaults to a 2.1 resolution unless you use the "magic" Soun Effect button on the remote and change it to a mode which defaults to 5.1. I had been pulling my own hair out between optical, LG Bluetooth and ARC options, all with 5.1 streams encoded but with NOTHING from the rear pair. Eventually I played with the remote rather than the GUI (which is exceptionally diabolical BTW). When you change the "Sound Effect" mode using the remote, you open up a whole new "world" not offered/presented at all in the "home" or Settings" menus. So, after figuring this all out without ANY reference in the user manual online or the ridiculous paper "quick start" guide that accompanied the product I am VERY impressed and happy. It's a great system with amazing punch and very good quality sound at a price point that's hard to resist. Don't be fooled by sound bars, this 5.1 system is the ONLY way forward IMHO

2nd time buying
I read a lot of reviews on this product and im bot really sure of the problems people are having, this is my 2nd unit after the 1st one was stolen I've had them for over 5 years now and just cant fault it, the issue where people are reporting sound/video sync issues or issues using arc I had this in the beginning and found swapping the hdmi cable(cheap) for a proper gold plated high speed hdmi cable fixed this issues after the swap it powered on and off and detected arc instantly even using a no LG branded TV, honestly think some people are to quick to blame a product before realising using cheap parts is normally the issue. Anyway sound quality is superb via any connection method, can't say I've tried the media drive as everything is digital nowadays the small speakers (for those unsure are actually designed to be at the front but if anyone hasn't notcied all 4 corner speakers are actually the same the tall boy speakers appear to have 2 speakers in but only actually reproduces sound from the top speaker but again unless you anally inspect things like me you wouldn't know the system in whole is very powerful I suggest placing the sub behind your sofa or under your bed depending what room you have it in trust me massive difference in how it sounds. Only 1 drawback in my opinion the receiver doesn't support 4k playback from media files but then it's not an issue as you'd generally plug your media source (hdd, usb) into the TV anyway which would use the arc function, also connected to a cheap Samsung TV the TV remote also controls the receiver. P.s if your having arc issues 2 points to make, make sure your using a decent hdmi cable and you have sync link switched on! Also if your complaining about port availability then its time to move with the times, this uses arc tech so plug everything into your TV set your TV to bypass and all sound is sent to the receiver rather then the receiver sending video to the TV, in my opinion I think this is a better set up which requires only 1 remote rather then having several things plugged into the receiver and having multiple remotes.

Great system
I got this from the warehouse deals so I got it for a great price. The only thing different was the box was slightly damaged, the speakers and blueray player are perfect. I bought this for my sim racing rig so they aren't used for movies etc. The sound is really good, the bass is nice and really makes running over kerbs etc sound great. The centre speaker means I hear the engineers voice perfectly when racing. I have the two tallboys behind the sim seat which means I can hear when cars are beind me and which side they are on. I'm am really happy with them, they suit my needs perfectly. The system was very easy to set up and the remote control is full featured and also easy to use.

The sound is wall shattering
Very well packaged and was easy to assemble just a few screws and colour coded wires you can't go wrong, connect to my LG TV and the sound is clear, room filling and fully adjustable to your liking. The centre and bass speakers pump out the normal action and voice then the front and rear speakers engulf you in total surround sound it is amazing. Was not happy with the default settings it came with, lets face it who is? Adjusted the speaker levels, EQ to my liking and never going back to watching even normal TV without these babies powered on. Blu-ray playback is flawless, radio also gives a good sound with presets and tuning easy to do. Inputs to allow other devices to connect and you can get on the internet wired or wirelessly to watch Amazon Prime video and other services. Lots of other features to explore like bluetooth playback from other devices that I haven't tried yet, but if the menu system is anything like the rest its going to be a pleasure and doddle to do. Best money I have ever spent

Ok ‘ish
I purchased as I thought it was time for a upgrade from my 800wt LG 5.1 system to this 1000wt -I guess I expected too much from this system - my old model was a 2011 and this a 2018 I thought sound quality would of been greatly improved..... it sounded nearly the same maybe voices a little more crisp but bass was worse..... I have now returned and spending a lot more on something that should melt my face off 😊

Impressive system
Very impressed with this system. Sounds great and is real value for money. I'm using it with an LG TV and it completely brings movies to life. Crystal clear sound even at low volume. The rear speakers can be put on a shelf, wall mounted or mounted on key hole compatible stands, as I have done. It's a shame the bluray doesn't play 4K discs - I would have paid an extra £100 for that feature, but it's still a fantastic system. Highly recommended.
