Considering the best that can be had for that price is say a pair of Wharfedales 9.0s or possible 9.1s and a CA amp, I think you'll be happy with them at a guess.
And I'm very fond of the inexpensive CA amps and the cheaper Wharfedales.
As an aside, as the CA Topaz 1 and Wharfedales 9.0s come in at £120 at Richer Sounds I can't imagine why people buy speaker docks and the like?
I bought exactly that combination for my 7year old nephew when I was very poor. In his room it's really something else. Either side of his tv his games explode with zest. Even cartoons sound cool. He loves them.
