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.

"Product is well put together. Looks stunning in Gloss Black. The sound seems more open in the mid's/high frequency compared to my previous speakers. I can hear more music at lower spl and this is a big improvement. In addition, the sound is coherent and not lagging in any way."
Mr I, Victoria

"Outstanding sound and stage! Very easy to set up. Best bookshelves I have ever owned."
Mr G, Winnipeg

"It has revolutionised the sound of my stereo, and given me the tone I've been looking for. So so happy. Thanks!"
Mr M, Horsham

"Good sound"
Mr H, Hong Kong

"Good and improving after only 25 hours of use"
Mr I, Poulton-le-Fylde

"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

"Nachde m ich durch die Fachpresse und einem Nachbarn auf euch gestoßen bin war ich nach dem ersten hören ziemlich schockverliebt"
Mr S, Moers

"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

"Amazing clarity, soundstage, resolution and ‘space” - even at low volumes."
Mr M, London

"Only had them a day, on the demo sounded fantastic, was excited to see how they sounded at home, out of the box, Wow!! And I know they need a run in but I’m extremely happy with my purchase- PMC- keep up the good work-A1++++ from me- thank you.."
Mr J, Hemel Hempstead

"Lovely"
Mr W, Andover

"Great speakers made better with good cable - just bought Audioquest Rocket 11."
Mr R, Sheffield

"nice"
Mr S, Guildford

"I’ve had my eye on pmc speakers for years but unfortunately they were out of my price range bringing kids up etc. I was now in a position to buy a pair and all can say is wow they were worth the wait! The sound quality is fabulous lovely top end, midrange and bottom end - sublime. All I can say is well done PMC, best speakers I’ve owned and I’ve had a lot of pairs from all the major speaker brands. Highly recommended"
Mr A, Sheffield

"I have used for less than ten hours but the potential is there!"
Mr B, Calamba City

"Wonderful!"
Mr J, Harlow

"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

"I had the Twenty5 21 speakers but decided to demo the 21i and could not believe the difference. Sweeter top end and the quieter parts of the music were so much better. Overall the sound has moved on in all areas compared to the previous model."
Mr M, Bristol

"Excellent sound quality, high resolution, wide spectrum, wide stage and amazing space rendering. Very good frequency transmission."
Mr I, Szeged

"Still running in sounding better ever day"
Mr C, Walsall

"As I write, the twenty5. 21i's are fresh out of the box, and sound wonderful without so much as an hours run in. Maybe I should revisit this comment in a few weeks time whereupon I'm sure they'll sound even better."
Mr M, Stoke on Trent

"I'm still running them inattentive the moment but even now they sound great."
Mr P, Cambridge

"Amazing sounding speakers with great looks to match."
Mr B, London

"The Twenty5 21i replaces my twenty 21 speakers. After extensive comparison, I can say that the Twenty5 21i is a significant improvement. The bass is nicer, better definition. The high is more spacious and all details are clearly displayed. Instruments are individually easy to follow. I'm very happy with it!"
Mr J, Nieuwerkerk aan den IJssel

"Very pleased as dealer let me borrow ones in shop already run in so sound in my own house was excellent I like port at front as I don’t have a lot of distance out from a wall This was a deciding factor as I had looked at the KEF R3 as also good reviews. But went for PMC on reputation and clear sound plus new model just out also swayed me Great finish on box also"
Mr I, Bangor

"When first installed, found the sound to be very thin and lean and the treble was harsh and bass very light. 4 hours later the sound had flourished into the best sounding speakers i have ever heard ! So full and musical and exciting to listen to ! Even my wife loves them ! I am using a Rega Elex-r amplifier with Cyrus CDI CD player and Chord Shoreline interconnects with QED 40th anniversary speaker cable. I havent tried using my Rega upgraded RP3 turntable yet !"
Mr C, Houghton LE Spring

"Best speakers I could ever wish to own. The build quality is beyond reproach and the sound is incredible."
Mr A, Witney

"That clean uncoloured sound that I was seeking was delivered."
Mr J, Worthing

"Very well packaged. Clearly both speakers and stands of high quality build. I have only just started to listen to the speakers paired with Naim Unity Atom, so need to run in. However first CD Pink Floyd, Wish you were here, sounds great. Speakers look superb."
Mr K, Tunbridge Wells

"I have owned numerous speakers including Mission, Monitor Audio and lastly Castle and I have never felt so immersed in the sound. It’s difficult to explain but you feel so involved. I have never been so happy with a purchase."
Mr I, Cumnock

"very good, high performance."
Mr M, Tai kok tsui

"By far the best speakers I have owned. As I have upgraded my system over the years, it was time to match it with speakers of a higher standard. The speakers compliment my system very well. They reveal the fine details whilst giving a much more consistent and full range sound over the entire frequency spectrum and at various volume levels. They are really fast and everything sounds more like real instruments and voices. Music is now even more enjoyable."
Mr D, London

"Don't judge straight out of the box, after about 50Hrs use the magic starts to happen."
Mr R, Tavistock

"Excellent customer service. Ian Sutton took the time and patience to talk to me several times, over the phone and via email, about the Twenty5 range. That made a difference and I’m very pleased with my purchase of the Twenty5 22. Stunning build quality and sound."
Mr D, Eastleigh

"Very pleased with these speakers. There are relatively few high quality speakers available that will work in a limited space for near field listening (eg on a desktop). Twenty5 21i are perfect for this purpose on IsoAcoustic desk stands. Bass quality and integration is superb. Mids and highs wonderful detailed. Wonderfully musical overall and very versatile."
Mr S, Okehampton

"Excellent and improving every day"
Mr J, Bristol
