Unsurprisingly the high end sets that we’ve seen recently are superior, but the VS2721 costs £50 rather than £170 or £200. If you can't afford the Corsair SP2500, the Altec Lansing VS2721 is a good but not spectacular alternative and is much cheaper.

Audio Alignment Technology for Superb Accuracy and Alignment
The BXR1221 relies on Altec Lansing's proprietary Audio Alignment technology to make sure all of the speakers' components work together to deliver your music the way it is meant to be heard. Audio Alignment technology offers the perfect balance of the three elements of the speaker system -- the drivers, enclosure, and electronics -- to ensure a natural, uncolored, and rich sound from your speaker system.
