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 ATL technology.

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

"I am still getting used to them, but they are a great deal more detailed than the previous speakers I had. These were a big upgrade for me."
Mr D, Woolloomooloo
"I wanted a bookshelf speaker for a Linn Akurate system with excellent resolution and bass response. Floor standing speakers were not an option for lack of space and my other half insisted on 'small' speakers. I was already impressed with PMC bookshelf speakers having heard a pair of DB1+. The Twenty5.21i fit the available space/size requirements. After about 36 hours run in we started listening to them on a regular basis. They work really well with the Akurate system which is quite lively in character. The Twenty5.21i present music with a well balanced frequency range lending clarity to both male and female voices, and excellent bass extension for the size of speaker. The audio image has a wide spatial spread and good depth, with clearly separated voices and instruments. We are really happy with the speakers and are revisiting old favourites in our music collection."
Mr I, Leicester
"The best stand-mount speaker I have ever listened to."
Mr G, weston-super-mare
"Sound is fab!"
Mr G, London
"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
