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.

Customer Reviews

"the speaker is simply excellent."
Mr A, Harrow
"Fitted all the criteria I had in mind, hearing them in the showroom ticked the main box, the sound, Once home they confirmed I had made the right decision, in a word, superb."
Mr R, Derby
"lovely, thank you."
Mr O, Abingdon
"My second pair of PMC and they are everything I wanted, I still love the 2021's but the 2521's have a much fuller sound. They are a different sound, they bring out natural warmth to my ears. They have detailed power, but still retain that unique PMC speed accuracy and control. Yet again I'm very happy. After a hard day I play music to unwind, sometimes for hours and my ears never tire. Thank you to PMC for your hard work."
Mr R, Grimsby
"Fantastic! previously hidden instruments & sounds now appear as if live."
Mr A, Sandy
"They’re amazing speakers for the size. They produce some excellent bass, amazing timing and sweet treble. Can’t praise them highly enough. Fantastic job PMC"
Mr J, Exeter
