As various people on various pages have remarked - this does not deliver a true surround sound comparable to having speakers and leads all over the place - on the other hand, you don't have to have speakers and leads all over the place! As you'd expect, all the sound comes from in front of you.
What it does deliver is an excellent quality, easily configurable (to personal taste, room size, sofa position etc) 5.1 sound, and with the surround sound feature switched on, it certainly gives an impressive 3 dimensional depth of sound vastly superior to the TV on its own. At last, I can hear dialogue over explosions, orchestral soundtracks etc!
It looks good too! We have a 37" Phillips LCD TV in black and it all looks very complimentary.
Very easy to set up and Amazon offered best price and reliable delivery. It was dead easy to set up and after about 20 minutes of turning center, mid and rear speaker volumes up and down and experimenting with DSP settings I had a sound that I was happy with. I had to turn the twin subwoofers down quite low, I'm not sure why they're quite so powerful - possibly you could use them for some sort of sonic warfare, or demolishing unwanted walls!
I'm very pleased!
