These are studio monitors so, as the above review says, they are going to sound pretty lame if you're trying to play to a crowd of thousands in a sweaty, packed warehouse. However, for studio recording (or i guess sat in your front room, bedroom) they are simply superb. Very flat response across the board no matter what the volume, ideal for studio work and if you are using it for TV, hifi etc at home, you will probably need to buy a bigger TV and stereo to do these bad boys justice.
