Features
- Dual 18" Active Subwoofer Configuration: Bass-reflex design optimized for powerful low-frequency extension and high sound pressure output.
- Superior Power Handling & Clarity: Delivers continuous rated power of 1200 W and peak power of 4800 W with maximum SPL of 128 dB. Symmetrical magnetic circuit reduces odd-harmonic distortion.
- Enhanced Thermal Performance: Utilizes 100 mm flat aluminum wire voice coils on high-heat-resistant TLL formers for efficient cooling and reliable prolonged operation.
- Ultra-Durable Enclosure & Coating: Built with 18 mm multi-layer plywood featuring an advanced coating process that provides 3x higher resistance to scratches and wear than conventional finishes.
- Weather-Resistant Protection: Powder-coated Q235 steel grille withstands 96 hours of salt-spray testing (5% NaCl) and includes backed mesh fabric to prevent direct rain intrusion.
- Optimized Port Design: Aerodynamically refined reflex ports drastically reduce port noise and air turbulence for clean low-end reproduction.
- Effortless Stacking & Array Rigging: Custom stacking bracket enables direct integration and fast, single-person angle adjustments with FLEXA 210A and FLEXA 212A line array speakers.
