- 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.
