Due to its complex ATL™ the twenty.21 has significantly more dynamic grip and depth of bass than any other speaker of this size.

It is a very effective musical communicator, with fine warmth through the mid range and a sweet and extended treble. It all adds up to a dynamite design, capable of dominating the compact loudspeaker market by reproducing all genres of music with ease.
