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.

Customer Reviews

"I'm very satisfied with my speakers."
Mr A, Calden
"I bought second pair of PMC loudspeakers. I have good experience of twenty.26 pair and now I'm ready to hear how twenty.21 works. After couple of days first experiences sounds promising."
Mr H, Helsinki
"Astonishing product. Please stay in the UK, don't sell out like some other brands have done. I love everything about my purchase. Exceptional build, sound quality and heritage."
Mr B, Reading
"Brand new and straight out of the box they sound a great deal better than my KEF Q300s, this is before they have even been run-in. The bass is more defined, the mid-range is a clear step up in quality with the highs showing great potential. Thanks PMC"
Mr J, Gainsborough
"Très bonnes enceintes, associées à un ampli Nuprime ida 8 et à un caisson de basse Vélodyne spl 800, l'ensemble marche très fort."
"Sounds amazing"
Mr T, Whitstable
