PMC 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 ATL technology.

An impressively large, coherent soundstage and refined midrange define the twenty5.21i: a compact transmission-line standmount that delivers low-distortion, low-noise playback with tight timing and surprising bass weight for its size. Reviewers from hi-fi+ and The Ear praise its smooth neutrality and studio-like control.
Pros
- Exceptional, expansive soundstage with layered imaging and off-axis tolerance.
- Smooth, neutral and detailed midrange that renders vocals and instruments with clarity and low coloration.
- Transmission-line loading and Laminair vent deliver unusually controlled bass for a compact standmount with low distortion.
&
Cons
- Limited low-octave extension and dynamic headroom compared with larger floorstanders; benefits from a capable amplifier and careful placement.

Bass
89/100
Transmission-line 5.5" woofer delivers surprisingly deep and well-controlled low end for a compact standmount. Multiple reviewers note reasonable 50Hz pressure, controlled cone movement and low distortion, and that placement near a wall increases extension; overall bass is exceptional relative to the cabinet size.
Mid
92/100
Reviewers consistently praise the smooth, neutral and detailed midrange with seamless integration to the mid-woofer. Comments highlight timbral accuracy, low distortion and an engaging, refined vocal/present midband that is both transparent and musical.
Treble
90/100
Soft-dome HF provides refined, airy treble with good dispersion and no notable hardness. Reviews mention delicate cymbal detail and consistent tonal balance across the top end.
Soundstage Imaging
94/100
Multiple reviewers report an impressively large, coherent and layered soundstage with excellent instrument separation and off-axis tolerance. Descriptions include 'incredible size' and 'large-scale imaging' giving a strong sense of presence and depth.
Dynamics
87/100
Timing and transient control are repeatedly commended ('impeccable timing', 'fine competence in timing'), though dynamics are naturally limited by standmount size and sensitivity; reviewers note good punch and power handling that exceeds expectations when paired with a capable amp.

Build Quality
92/100
Robust construction: folded HDF transmission line bracing, long ATL, high-quality crossover implementation and premium terminals. Reviewers emphasize inert enclosures, careful damping and durable component choices.
Features Connectivity
80/100
Passive single-pair binding posts — baseline passive bookshelf score applied per rules. Terminals are high-quality (rhodium-plated) but no bi-wire/extra connectivity to adjust baseline.
Value for Money
90/100
Reviewers call them hard to fault and among the best small standmounts for the money; price points cited (~£1,995–£2,195) and strong peer comparisons underpin a high value rating for their class.
