Here's what Sonor say:
With the AQ2 Series, you can choose out of a broad range of pure maple drums offering the ultimate combination of great sound, setup flexibility, a wide choice of finishes and portability.
The AQ2 Series drums come with newly designed shell hardware and a new tom mounting system: the SmartMount. This minimalistic yet functional mount has the true German design and engineering spirit inside: optimal sound sustain with a minimal amount of hardware on the drum shell. Finally, the stunning White Marine Pearl Delmar wrap finish tops off this minimalistic shell very nicely.
