PMC twenty5.24i
PMC’s twenty5.24i pairs deep, controlled bass with explosive transient speed and an expansive, stable soundstage—rare authority from a slim two-way floorstander. Its Advanced Transmission Line keeps low frequencies taut and tuneful, while the revised tweeter brings airy detail and convincing texture. The Ear found it especially revealing, dynamic and engaging across music at both intimate and serious levels.

Pros
Exceptionally deep, fast and well-defined bass that remains controlled rather than bloated, even at high volume.
Explosive dynamics, precise timing and strong transient attack, while retaining subtle low-level detail.
Wide, stable imaging and convincing off-axis performance create an open, almost holographic presentation.
Cons
The slightly laid-back upper midrange can reduce vocal intimacy and upper-register piano timbre.
Needs careful placement and capable amplification to fully control its powerful bass and realise its dynamic potential.
Using the fabric grilles can slightly smooth the treble and flatten the soundstage.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 93/100
Reviews portray a fast, open and highly resolved floorstander with unusually deep, controlled bass for its slender two-way form. Its greatest strengths are timing, transient definition, stable imaging and an ability to remain engaging from low listening levels to high output, although the upper-mid voicing is slightly laid-back and grille use can compromise openness.
Bass
96/100
Reviewers repeatedly praise bass depth, speed and definition, with effective output below 30Hz from the transmission-line loading. Tech Reviews found it never woolly or exaggerated even at volume, while The Ear heard strong bass with notably controlled driver excursion on demanding electronic music.
Mid
90/100
The midrange is described as lucid, forgiving and well integrated with the updated tweeter, with especially convincing string texture and lower-mid body. There is a recurring mild reservation: Tech Reviews and The Ear both heard a slightly withdrawn or laid-back upper midrange that can reduce vocal intimacy and upper-piano timbre.
Treble
92/100
The revised tweeter earns praise for clearer vocal articulation, cymbal texture, air and a more resolved presentation than the prior model. It is incisive and revealing without being widely judged harsh, though The Ear found the top end less smooth when the grilles were fitted.
Soundstage Imaging
93/100
Stereo perspective is described as rock solid by Tech Reviews, while hifitest.de heard striking coherence, level stability and an almost holographic room presentation. The Ear also reports strong openness and image definition, but notes that the grilles can flatten the stage.
Dynamics
95/100
The speaker is repeatedly celebrated for explosive transient attack, serious output capability and the ability to preserve subtle detail at very low levels. The Ear calls its speed and resolve breath-taking with suitable electronics, while hifitest.de found it equally unfazed by subsonic bass and delicate microdynamic material.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
94/100
hifitest.de calls the build outstanding, highlighting veneers applied inside and out for a stable, homogeneous enclosure and noting the long warranty. The Ear also documents substantial engineering in the HDF cabinet, cast-alloy driver chassis and flagship-derived tweeter technology, although long-term ownership evidence is limited.
Value for Money
89/100
At an asking price of roughly 6,575 to 7,890, the twenty5.24i sits firmly in the premium floorstander market. Hifitest.de rates value for money as very good, and the reviews support that verdict with unusually full-range, dynamic performance from a slim two-way design; buyers should nevertheless budget for amplification and source components commensurate with its revealing nature.
