I had used the klipch promedia ultra 5.1 surround system for 5 years until the subwoofer failed.... I decided to purchase the logitech Z-5500 after reading the reviews here and I am totally impressed with the sound quality the logitech performs......I recommend this system to anyone who is a serious gamer.
