If you've read any of the speaker reviews on the 'Net you've no doubt realised that good speakers cost good prices. The old addage that you get what you pay for is particularly true when it comes to PC speakers, while those designed to turn your living room into a mini home cinema often carry ludicrous price tags. So what can you do? You're fed up with lifeless, tinny sound but you really don't want to lay down in excess of £150 for the privilege of something that only seems to matter to you when you've got a film, MP3 or music CD on.
