From the manufacturer:
The answer to the question is drums that give you the sound you need, whenever you need it.Tonal requirements vary among drummers, differ with dynamics, and change, from band to band, song to song, moment to moment. With the Absolute Hybrid Series drums, Yamaha has succeeded in addressing this, with a drum set that possesses an extraordinary degree of expressive power, allowing drummers to pursue a level of expression that perhaps they've not experience before in their other drums. These drums offer a wide dynamic range that allows them to respond accurately to each and every stroke, and follow changes in dynamics, nuance, and touch, letting you play what you want to play.
