A masterclass in controlled low-frequency authority, the twenty5.24i couples PMC's ATL and long-throw woofer to deliver fast, tuneful bass and remarkably low distortion. Its wide-dispersion tweeter yields an open, natural soundstage with smooth off-axis response, while the design rewards high-quality amplification with breath‑taking transient speed. Reviewers (see The Ear) praised its musical clarity.
Pros
- Deep, controlled and tuneful bass delivered by PMC's ATL and long-throw woofer, with minimal cone excursion even on heavy material.
- Wide-dispersion tweeter and low 1.7kHz crossover create an open, natural soundstage with smooth off-axis response and excellent imaging.
- Exceptional transient speed and dynamic control when partnered with capable amplification, giving punchy attack and rhythmic drive.
- High mechanical refinement—long-throw g-weave cone, ferrofluid-cooled Sonomex tweeter and tuned plinth dampers—reduces distortion and tightens definition.

Cons
- Needs more amplifier power than the 89dB sensitivity suggests; reviewer recommends roughly 50–200W per channel for optimal headroom and dynamics.
- A gently laid-back upper midrange can reduce intimacy on stripped-back, singer-songwriter recordings.
- Slim magnetic grilles cause minor diffraction that may soften the top end and slightly flatten the soundstage when fitted.

Bass
95/100
PMC's ATL loading and 6.5" long-throw woofer extend to 27Hz in-room and deliver controlled, tuneful low end. Reviewers noted woofers 'barely twitching' even on heavy bass and praised the speed and authority, indicating sub-bass competence beyond what the driver size alone might suggest.
Mid
90/100
Mids are lucid and resolving with immediacy to plucked strings, though the upper mid is described as slightly laid-back, reducing singer-songwriter intimacy. Overall timbre is accurate and coherent through the crossover, benefitting from the low 1.7kHz XO point.
Treble
91/100
Tweeter is incisive, airy and refined (Sonomex soft-dome with ferrofluid cooling and tech from the flagship), giving detailed highs and smooth off-axis response. Minor grille diffraction was noted when drivers are covered, slightly softening the top end and soundstage.
Soundstage Imaging
92/100
PMC's wide-dispersion philosophy and low crossover deliver an open, natural presentation with excellent image definition and reverb clarity. Damping between cabinet and plinth improves separation and focus; grilles slightly flatten the stage.
Dynamics
93/100
Reviewers highlighted 'breath-taking speed', exceptional transient attack and thrilling dynamic control when partnered with capable amplification. The speaker rewards power and high-quality upstream gear; more drive yields greater slam and headroom.

Build Quality
92/100
Slender HDF enclosure, cast-alloy chassis for the driver, long-throw g-weave cone and a tweeter derived from the flagship indicate high engineering standards. Included plinth-damping discs and solid finishes underline careful mechanical design and resonance control.
Features Connectivity
80/100
Passive two-way floorstander — baseline passive tower score applied. Standard single pair 4mm binding posts; included plinth damping is useful but feature score capped by passive baseline.
Value for Money
78/100
No price provided; reviewers describe the 24i as 'infectiously peppy' and highly revealing but recommend quality amplification. Without explicit pricing or peer comparisons, value is judged cautiously positive based on performance claims.
