Fps stands for four point stereo and it's different from the fps 1000 because the sub woofer has been redesigned
For my birthday I wanted a good speaker set. I thought that my allowence (£50) would buy me an ok set of speakers. I wasn't expecting a 5 piece speaker set with exelent qualitie. The set comes with 4 little speakers and a fairly big sub-woofer that can pump out some real phat bass!!If you have a surround sound soundcard you will have a tottally amazing gaming and audio experience. You will be immersed in the game. It's still brilliant if you use it with a normall soundcard. I love the way you hear all the sound from behind you as well as from infront of you. Many reviews of this product have said it's a revolution in audio experience.I think it's amazing. The difference between this and the Fps 1000 is the sub-woofer it has been redesigned for a fuller bass response and believe me the bass will blow you away. It also got a little knoby thing to change the volume, this comes in very handy because on some models it's on the bass unit and your supposed to put that on the floor out of the way. To sum up it's a great speaker set and you won't get better than this unless your prepaired to pay alot of money.....Alot!!
