Here's more details directly from Alesis...
With the groundbreaking Alesis DM10 module, a comprehensive set of large electronic drums and cymbal pads, and an all-new Xrack, the DM10 X Kit is designed to offer capabilities and features previously only available on kits costing thousands more. The DM10 X Kit features an expansive six-drum, four-cymbal configuration with sizes and spatial relationships that will feel natural to acoustic and electronic drummers alike: a 12-inch snare, two 10-inch toms, two 12-inch floor toms, a 12-inch hi-hat, a 16-inch, three-zone ride cymbal and two 14-inch crash cymbals.
Designed with an emphasis on performance and adaptability, the DM10 X Kit's all-new Xrack is rugged, chrome-plated and features an ultra-solid four-post design. New Alesis quick-release clamps secure each pad in place and allow drummers to rearrange their setup in seconds without tools and without having to the rack apart. A few turns of a T-bolt is all it takes to release a clamp and move a pad. The DM10 X Kit's snare pad comes with a separate, fully adjustable snare stand that allows drummers to place the snare pad precisely where they want it.
With the DM10 X Kit, Alesis unveils a new-look DM10 module, which contains more than 1,000 uncompressed, sample-based sounds that were produced using Alesis' proprietary Dynamic Articulation™ technology.
