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

"The PMC twenty5.21i replaces the previous PMC twenty5.21 in my main Linn/Naim system. The original twenty5.21 speakers are now in my secondary system in the bureau (all Naim apart from the PMC speakers). I therefore have a direct comparison between the old and new speakers. For the first few hours the sound from the new speakers was slightly thin and trebly; not surprising as many new components show this before they're run/burnt in. Twenty hours in and they are now sounding really good, with the treble sweet, bass communicative and a definite improved depth to the sound stage. The original speakers are excellent but the new range is certainly a step forward. Vocals are more "there" and the sound stage more authoritative. A definite recommendation!"
Mr C, BROMSGROVE
"From the box they filled my room with clear detailed sound with surprising bass. Haven't felt the need to add subs, the aesthetic is classic and unobstructive with their small form factor. Looking forward to hearing them develop as I run them in."
Mr J, West Albury
"Delighted!"
Mr G, DEBDEN
"Cristal clear dynamic sound even better than expected."
Mr J, Paris
"They seem to have played-in very quickly. Great sound already. I particularly like mod and contemporary jazz and have over 7000 CDs. I now just want to play everything again, but the wife and dog won't let me ;-) Love the detail, love the bass. Not missing my B&W floor standers one bit. Soon moving to a new house where my music parlour will be slightly smaller that what I'm used to, but don't really care, my new PMC's will sort everything out. Blessings!"
Mr D, Brtistol
"Love the sound so far - still running these puppies in. I'm stoked to have some speakers that reveal the music (for good and bad frankly) and my system! - I'm going back over my CD / records collection to find the good stuff that has been properly recorded ... AND I feel I can actually benefit now from the expensive upstream electronics that I have purchased over the years. thanks PMC :)"
Mr M, Amberley
