The PMC Twenty5 21i - To kick start off this fantastic series, the Twenty5 21i is the smallest and most compact speaker in this new range, as always when you see a small speaker around this price point, you will certainly not be left disappointed when it comes to sound, the sound from this speaker is something you'd expect out of a much larger cabinet speaker; this is all thanks to PMC's Advanced Transmission Line Technology. The Twenty5 21i is perfect for those small-to-medium listening environments where space is at a premium, but still gives you that detailed bass, fantastic mids and very fragile highs with maximum musicality. Placements of these speakers are entirely down to yourself, you can either have them mounted or placed on some stands. Nevertheless, this speaker will offer you maximum flexibility for placement and not only that, but they will also look the part in any sort of environment; this comes in numerous finishes which you can check out above.

We touched upon PMC's ATL (Advanced Transmission Line) technology, to get some context on what this is, it's a technology that uses sophisticated cabinet construction, proprietary drive units, and patented absorption materials and techniques. The benefits you get from this are rather substantial compared to the relatively simple sealed and ported designs currently available elsewhere.

Although the Twenty5.21i is the most compact model in the twenty5 series, it does not have a small sound. Having listened to the speakers extensively in our Hereford store on a variety of amps from the likes of Rega, Naim and Audiolab they never failed to impress. Ideally suited for use in a small to a medium-sized room where space is limited, the 21i offers maximum flexibility while still offering natural mids, open, detailed highs and class-leading bass performance for a speaker of its size. Happy to be used on a bookshelf or with a pair of stands such as the PMC Twenty5 stand. One of my favourite compact combos with these speakers is the Rega Brio amplifier, perfect for rooms where space is at a premium but still want a quality sound.

Who is PMC?

Founded in 1991 by Peter Thomas of the BBC and Adrian Loader of FWO Bauch. The combination of knowledge and a life-long passion for music led to the production of PMC’s first product, the BB5-A, an active main studio monitor. This design was snapped up by the BBC Maida Vale and Metropolis Mastering and remains the world’s reference, used by Prince, Stevie Wonder’s Wonderland Studio, Hospital HDTV Broadcast London and renowned classical labels such as Decca and Harmonia Mundi. Many of today’s movie themes have been crafted using PMC, by such eminent composers as Henry Jackman, Thomas Newman, Tyler Bates and John Debney.
