Speakers definitely improve sound surround with my Samsung Soundbar. You will need to buy stands for them if you don't have a specific place to put them. This was a bit tricky, getting suitable wall mounts but did manage to find some

Not cheap, but do make my S800D soundbar sound better.

Overall, sound quality is pretty good. Both front and upfiring speakers are a little on the quieter side even when channels are turned up further but, with the right content, you can certainly experience some fantastic surround sound. Very easy to connect to a compatible soundbar. During install, you will immediately notice the rather limited length of the power cables supplied. I did need to go and purchase some longer cables in order to plug the speakers in where i wanted them while also cable managing. If you have a Q series soundbar and are looking to get that little bit of extra cinematic experience, i would recommend these speakers.
