From Martin's website,

"The X Series is made to play. The acoustic-electric D-X2E Brazilian 12-String features a hand-rubbed satin spruce top with an elegant abalone pattern rosette and eye-catching Brazilian rosewood pattern high-pressure laminate (HPL) back and sides for added durability and looks, without sacrificing that classic Martin tone. Playability enhancements include a thinner fingerboard with a gently beveled comfort edge and refined string spacing, and a modernized bridge contour for a smooth and comfortable playing experience. It also features a select hardwood neck, fingerboard, and bridge for improved sound and sustain, and Martin E-1 electronics with a built-in chromatic tuner and volume, tone, and phase controls. The D-X2E Brazilian 12-String's iconic Dreadnought body size is loud and projective with strong bass, lending itself to any genre and experience level, while the extra strings provide a unique layer of chime, tone, and texture. All X Series models come with a softshell case."
