Sabian HHX 17 Inch Studio Crash Description: HHX Projection. HHX puts out rich, simmering tones that burn through the coolest music. Super-sized hammering and an exclusive Tone Projection feature add bite to project the musical sounds of HHX through everything from pumped-up grooves and thickly textured tracks, to guitar-heavy, high-end wailing. HHX combines the best of two worlds, Traditional Tone and Modern Projection. With HHX compromise is not an option. Thin design for fast and full accents loaded with a bright tone that shimmers with pure musicality.
