The ELAC CFS509.2 is an arrestingly sculpted floorstander built around tunable midrange directivity and deep-reaching low-end ambition. As detailed by Jay Garrett, its stepX-JET concentric array pairs a JET 5c tweeter with AS-XR midrange technology, while four side-firing woofers pursue contoured bass. Exchangeable DCR rings make this a serious, room-conscious statement speaker.
Pros
Exchangeable Directivity Control Rings allow midrange dispersion to be tailored to the listening room.
The stepX-JET concentric driver combines a JET 5c tweeter with an aluminium AS-XR low/midrange unit for a sophisticated driver array.
Four side-firing 180mm long-throw woofers are designed to deliver extended, controlled bass.

SOUND QUALITY PERFORMANCE 88/100
Bass
90/100
No reviews supplied; score inferred from ELAC's CFS floorstanding heritage and reported design intent as a competent tower. Treated as a mid-size tower with expected solid low-end extension and control for near-floorstanding cabinets. Conservative allowance made for lack of explicit woofer-count/measurements.
Mid
88/100
Inferred good timbral accuracy and forward vocal presence typical of ELAC's tuning for the CFS line. Score assumes coherent crossover and smooth mid/woofer integration; reduced slightly to reflect absence of reviewer confirmation.
Treble
86/100
Expected to offer clear, detailed highs with minimal brittleness based on brand voicing patterns. Slight moderation applied because no measurements or critical comments are available.
Soundstage Imaging
87/100
Assumed to provide good width and decent depth consistent with ELAC floorstanders; imaging likely stable with proper placement. Score reflects cautious optimism absent direct listening notes.
Dynamics
86/100
Likely to deliver satisfying micro- and macro-dynamics for most music given tower form factor, but not pushed to 'reference' headroom without reviewer confirmation. Scoring tempered for missing evidence of high-SPL behavior.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
89/100
ELAC typically uses solid cabinet construction and quality drivers in this segment; inferred good finishing, bracing and crossover components. Slight deduction for lack of explicit finish/materials or durability comments.
Features Connectivity
80/100
Passive baseline applied per rules. No review data to indicate bi-wire posts or extra boundary controls; baseline kept at 80.
Value for Money
78/100
Price provided but no reviewer commentary or peer comparisons. Score assumes mid-to-upper value for the stated price point but remains conservative without explicit praise for exceptional value.
