We have a number of models in this price point, and generally, people tend to choose the Monitor Audio Bronze as they're the most neutral, balanced budget speakers - BX1's usually for those who want something compact, or the BX2's for those who want a 'bigger' sound, which is a little more effortless. The Wharfedale Diamond 10.1's are liked by those who like a bit of bass, and the Mission MX1's for those who want something in between.
They all have their own signature though, so it's best to pop along to a dealer where you can have a listen to a few and find a pair that suit your music/ears/taste etc.
