£32 if you collect from store or £36.95 with delivery. There's only three reviews of the system on the site but they're all good. No information about the system on the site though, which isn't very helpful. So I've pasted one of the reviews from a customer below because it contains some information about the system.
Was a little sceptical with this purchase at first but this product is the exception to the popular saying “you only get what you pay for”. For a mere £40 this system delivers quality 5.1 channel surround sound. Crystal clear crisp sounds with deep rich bass tones. I actually bought this for my bedroom after already having a Logitech x 540 5.1 system in the lounge which I think cost double the Asda system and at the time that was cheap. In the end I moved the Logitech upstairs and used the Asda one in the lounge as I think it looks more stylish and less space ship like. Personally I could not tell any difference in the sound apart from when hooking up in 2.1 channel for stereo the Logitech system was better and created 5.1 audio from a stereo input.
The Asda system gives 75W Total from 5 x 10W satellites and a 25W Sub which is adequate for a medium to large size room. It has all the cables built in just plug in the phono plugs into the back it also has phono inputs for Stereo and or 3 x 5.1 systems. Simple and tidy setup no messy striping of wires although you might need an extension if your room is too long.
If I had to pick faults then I would say the remote looks of cheap build quality. It does allow independent volume control for front and back speakers. Also allows you to choose the input method but there are also side mounted volume and channel selection controls on the sub woofer.
The black and silver allows it to look good if your setup is either of these colours and it definitely is comparable in looks to some of the top end £250+ systems. No Asda branding on show so nobody would know where you purchased it from.
For only £40 I think it is a must buy bargain of the year!
