A surprisingly authoritative sound from a small package ; Impressive detail resolution and agility ; Fine build

Don’t sound half as impressive when played at very low levels

Our first impression was that PMC had been a little ambitious with the pricing of the Twenty 21s. Having got them to sing, we feel they’re one of the best speakers around at this price level. An easy five-star verdict.

Incredibly authoritative sound from a small speaker ; Superb build ; Handsome looks

Won't flatter poorer material ; Stands are relatively pricey ; Demanding on partnering equipment
