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

"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
"I am currently waiting one my pair of twenty.23s to arrive, but in the meantime I am loving my 21s as the front stereo pair. They interface really nicely with the REL S3 subwoofer that I am using, together they create a lovely integrated sound even right down into the lows."
Mr R, Hitchin
"Fantastic, best of many speakers I've had by far."
Mr C, Cork
Mr A, Stafford
"Not only do I love the way they sound and look, I just love owning them."
Mr K, Kenilworth
