Deliciously Crispy

The Platinum 100 3G serves an eloquent midrange that blends effortlessly with deep, textured bass and a crisp, controlled top end from its MPD III tweeter. Reviewers praise its dynamic control and wide, well-defined soundstage, with Simon Lucas noting its authority and musical coherence across levels.

StereoNET United Kingdom

"this little loudspeaker is the very model of accomplishment."

Pros

  • Deep, textured bass with tight control and low-frequency extension (ported design tuned to 44 Hz).
  • Crisp, authoritative treble from the MPD III tweeter that delivers sparkle without edginess.
  • Eloquent, revealing midrange that conveys vocal detail with seamless integration between bass and treble.
  • Strong dynamics and a well-defined, stable soundstage that remain coherent at both low and high volumes.

&

Cons

  • Needs high-quality upstream electronics and careful placement (rear-firing port) to realise its full potential.
  • Premium pricing for a compact standmount may temper value for budget-conscious buyers.

Sound Quality

92/100

Bass

90/100

Reviewers repeatedly praise deep, textured low end and note the reflex port tuned to 44 Hz and a claimed in-room response to 28 Hz; for its size (6" woofer, ported) the speaker delivers exceptional low-frequency extension and control.

Mid

93/100

Midband is described as 'torrential' and 'eloquent', revealing vocal detail with body and seamless integration with bass and treble; reviewers highlight excellent communicative power and clarity.

Treble

92/100

Top end 'attacks with crisp authority' yet avoids edginess or hardness; reviewers report a natural, convincing sparkle with substance and shine without sibilance.

Soundstage Imaging

91/100

Soundstage is well-defined with good image focus and stability; reviewers note preserved boundaries and no blurring even at high levels, giving clear instrument placement and depth.

Dynamics

92/100

Dynamics and control are repeatedly praised ('control is absolute', clear contrasts between verse and chorus); the speaker conveys tempo and punch with authority and maintains detail at low levels.

Build Quality

92/100

Described as 'beautifully constructed' with anodised metal trims and high-quality finishing; crossover and driver execution are called-out as carefully engineered.

Features Connectivity

80/100

Passive bookshelf baseline applied (single-post passive). Crossover design noted (elliptical filters for time-alignment) but no additional terminals or DSP; baseline 80 maintained.

Value for Money

80/100

At a high price point (~£/€/$4,500) reviewers call it 'among the most engaging loudspeakers pound-for-pound' but stop short of 'best-in-class' value claims; excellent performance but premium cost tempers value score.
