Although the twenty5.21i is the most compact model in the new range, there’s nothing small about the sound, which has the impact you’d expect from a much larger cabinet, thanks to PMC’s ATL technology.

Although the twenty5.21i is the most compact model in the new range, there’s nothing small about the sound, which has the impact you’d expect from a much larger cabinet, thanks to PMC’s Advanced Transmission Line technology. The speaker is ideal for use in small-to-medium listening environments where space is at a premium, but where you still want detailed bass, ultra-realistic mids and delicate highs with maximum musicality. Equally happy mounted on a stand or a bookshelf, the twenty5.21i offers maximum flexibility for placement, and also makes an excellent choice for effects speakers in an immersive sound system.

Customer Reviews

"Good sound"
Mr H, Hong Kong
"Amazing Sound"
Mr R, Old Bar. NSW
"A replacement for my 23 year old TB1s. They are similar in character but much more detailed all round."
Mr A, Milton Keynes
"Still running in but already sounds excellent even when compared to my FB1+. May be old but still performing commendably (the speakers,that is ! )"
Mr G, Chesterfield
"Dolci dettagliate dinamiche , con bassi insospettabili per il volume del mobile. La scena è impeccabile con molta aria. Un sound di altissimo livello."
Mr F, VENEZIA
"Compared to the speakers I have been using for the past 12 years they are a revelation. I hadn't realised how much I was missing on all fronts until listening to the PMCs."
Mr R, Sheffield
