I spotted these while looking for a set of 5.1 speakers and thought it was worth posting on here.
You get two pairs of Monitor Audio Vector 10 speakers for the front and rear, the Vector 20 centre and VW-8 subwoofer plus a reel of half decent speaker cable.
Mine turned up yesterday and the build quality is excellent and they sound lovely - vastly better than you'd expect for £300.
Original retail price was somewhere between £600 and £700 and it shows.
Here's a review of them when they were twice the current price.
A big thumbs up to the retailer as well - next day delivery for free with tracking updates sent by email and text message to my phone.
