8331ARW

RAW Aluminium Finish
Sustainably unpainted die-cast aluminium housing offers a unique industrial look with reduced environmental impact and added surface durability.

Ultra-Compact 3-Way Design
Combines midrange, treble, and dual concealed woofers in a footprint smaller than most 2-way monitors which is ideal for small rooms and nearfield setups.

Exceptional Frequency Range
Delivers 45 Hz to 37 kHz (−6 dB) with ±1.5 dB precision from 58 Hz to 20 kHz, ensuring accurate tonal balance across all content.

Dedicated Triple Amplification
72 W for bass, 36 W for midrange, and 36 W for treble, all Class D, for clean, efficient performance at any level.

MDC™ Coaxial Driver
Ensures phase-accurate point source performance with ultra-low distortion and fatigue-free listening, even during long sessions.

Acoustically Concealed Woofers (ACW™)
Delivers clean low-end performance without disrupting the mid and high frequencies, enhancing clarity and imaging.

Room-Optimised with SAM™ + GLM™
Works with Genelec Loudspeaker Manager software to automatically calibrate to your room and optimize EQ, timing, and phase response.

Energy-Saving ISS™ Mode
Automatically enters standby at ≤0.5 W power consumption when idle, reducing energy use in professional environments.

Professional Connectivity
Supports analog XLR input, AES/EBU digital input and output, plus dual RJ45 ports for full GLM system control.

Fully Equipped for Studio Use
Package includes the 8331ARW monitor, Iso-Pod™ stand, mains cable (1.8 m), RJ45 control cable (5 m), operating manual, and The Ones brochure.
