DW provides drummers with yet another sonic option, while at the same time utilizing renewable resources, that"s ECO-X. They are big, full sounding drums with a huge fundamental, and all of the warmth, resonance, and attack that Collector"s Series drums are known for. This Eco-X floor tom not only satisfies drummer"s needs with its huge sound, and full frequency range, but it also satisfies our need to be environmentally conscious. The unique hybrid bamboo/birch shell provides increased high-end attack, while DW"s X Shell technology offers unprecedented low-end response. Plus, DW drummer-friendly features such as True Pitch Tuning, STM (Suspension Tom Mounts), Proportional Counter Hoops and DW Heads by Remo USA all come standard. It"s a giant leap forward in shell technology and everyone wins!
