High-End Driver Configuration

The Echtelion Towers feature a premium European driver lineup selected for transparency, speed and tonal accuracy:

Tweeter
• Scan-Speak Revelator Ring Radiator R2904
Extended response up to 40 kHz, exceptional micro-detail retrieval and controlled dispersion.

Midrange
• Audax Aerogel HM100Z0 Prestige
Ultra-light Aerogel cone for extremely fast transients and outstanding neutrality in the critical midband.

Woofer
• Custom carbon fiber cone woofers
Woven carbon fiber cones combining low mass and high rigidity for precise, controlled and articulate low frequencies.

Reference-Level Crossover

The crossover network has been designed and hand-assembled in dual-mono point-to-point configuration, with no compromise in component quality:

• Mundorf MCap® EVO Oil capacitors
• Mundorf MResist® Supreme resistors
• Air-core inductors

This layout ensures minimal signal degradation, preserving harmonic structure, dynamics and phase coherence across the entire frequency range.

Cabinet Construction

• Fully handcrafted enclosure
• High structural rigidity to eliminate unwanted resonances
• Precision driver mounting and mechanical decoupling
• Carefully engineered internal damping
• Carefully engineered internal damping
• Custom support feet in solid milled stainless steel
• Custom rear binding post plate, machined from solid stainless steel

Each pair is individually built and calibrated, following a coherent acoustic philosophy rather than commercial constraints.
