twenty5.21i
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

"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."
