I don't know where to start. These speakers are just amazing, the clarity this speaker set delivered was unmatched. Even the Logitech Z-680s could not compete with the Z-5500s. Both sets are incredibly loud and offer superior bass than anything I've owned before and yes, I've even owned Klipsch and Bose Speakers. The control over the surround effects was also impressive, turning my room into a venue many times bigger with a twist of the control knob on the Surround option.
