Compact, Elegant Cabinet: Designed for Performance and Beauty

• GoldenEar BRX model-inspired curved (extended-surface) top panel better minimizes cabinet resonances
• Increased wall thickness prevents absorbing and smearing important bass transient information and impact
• Perforated metal grill affords improved sonic transparency and airflow
• Gorgeous and subtle Satin-Black finish

Robust, Efficient Amplifier: Upgraded Electronics Platform Based on the Award-Winning SuperSub X/XXL

• GoldenEar SuperSub-inspired electronics with Analog Devices DSP affords flatter, more extended frequency response for cleaner, deeper bass with lower distortion
• MOSFET output stage and improved implementation result in greater power-transfer efficiency
• Necessary subwoofer Level and Low-Pass filter controls allow easy optimization for home theaters, hi-fi setups, and living environments

Optimized Driver Configuration: Superb Detail, Soul-Stirring Bass

Ultra-Long-Throw Sub-Bass Driver

• Superior transient performance for natural detail
• Computer-optimized ultra-stiff fiber cone
• Massive high-gauss magnet assembly

Quadratic Planar Infrasonic Radiator

• Downward-firing pressure-coupled loading extends usable bass performance to the infrasonic region
• Approximates the near-perfect impedance of a well tuned transmission line, but with superior transient performance and control
• Affords outstanding flexibility for room placement

The overall result is agile, musical, room-filling bass equally suited to thrilling soundtracks, stirring orchestral pieces, propulsive pop music, and everything in between. The new ForceField 30 and ForceField 40 achieve GoldenEar's mandates for any subwoofer:

• To be subtle and invisible, allowing a string bass or a fighter jet’s roar to seem to come out of nowhere
• To unignorably do its job when the pluck of a bass guitar or a giant’s footsteps are supposed to rumble your soul
