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.
DEEPER, CLEARER, CLEANER BASS & MORE
The source of PMC’s legendary natural, realistic sound is the Advanced Transmission Line (ATL) bass-loading technology, professionally proven all around the world.
ATL uses energy generated by the bass unit in a much more intelligent, efficient way than speaker designs based on ported or sealed boxes.
