The twenty5.21 is proof that great things come in small packages. Don’t let its compact size fool you; this loudspeaker is nothing less than remarkable. Its complex ATL and Laminair  vent mean that you get speed, weight and transparency, with the greatest bass extension of any loudspeaker this size.

Whether on a shelf or its performance-enhancing stand, the twenty5.21 excels with all types of music. Its articulate mid-range, clear, open highs and profound bass mean it can fill rooms both medium and small with astonishing ease.

Mr M, Tonbridge
"I loved my 2021 for one and a half years and I've changed it to the 2521 which I hope to love for the next 20 years. When I listen to the 2521 its like I´m sitting at a concert on Gods right knee......"
Mr S, Copenhagen
"I was very impressed with the Twenty5 series when I first heard them demonstrated. Having now added a pair of Twenty5.21's to my own system, they exceeded my already high expectations. Amazing level of detail and balanced sound from such small boxes. They look fantastic too with a very high quality finish."
Mr T, Ickenham
"Excellent speakers for use in our garden room with a Naim Atom and TQ black speaker cable. Holds it's own against the front room system which cost ten times as much a few years ago. But we do love Bryston amps......."
Mr A, Ellesmere Port
