SOUND QUALITY PERFORMANCE 86/100
Bass
88/100
Specs indicate strong low extension (LF cutoff -10dB at 20Hz; ±3dB 25–150Hz) and a 10" glass-fiber/PMI sandwich woofer with a balanced drive motor. No reviewer measurements or listening outcomes were provided, so score is inferred from measured spec sheet rather than independent listening comparisons.
Dynamics
82/100
10" driver with balanced drive motor, die-cast basket and recommended 40–200W amplifier suggest good transient control and headroom for its size. In absence of dynamic-response listening tests or reviewer comments, rating is inferred from motor/driver design and power handling.
Assessments of Build Quality, Usability, and Overall Propositions.
Integration
74/100
No reviews or listening reports supplied that describe room integration or 'disappearing' blending with mains. Spec items (wall bracket/floor stand, recommended power 40–200W) enable flexible placement and matching, but Features ≠ Integration; add outcome evidence or lower Integration.
Build Quality
86/100
Solid materials listed: MDF cabinet, die-cast basket, glass-fiber/PMI sandwich cone and rubber surround indicate robust construction. No durability or finish issues reported in reviews because no reviews were supplied.

Value for Money
