Highlights
- 3”ASV voice coil wounded for hi-temp performance, 4+4 ohms
- 2X3000 watts max power continuous program power rating makes high acoustical output
- All-black body with metallic feel. Won’t be wrong.
- 87 dB sensitivity, top in the similar class!
- Excellent low frequency ability, high fidelity response
The magnet thickness is increased by 15mm for better heat dissipation, enhancing sound purity and fullness. Features a high-elastic rubber diaphragm, silk wave, and powerful performance.
The pole core is attached to the heat sink with heat-dissipating glue, and waterproof glue is applied to the diaphragm for improved waterproofing. The woven mid-bass unit is injection-molded with high molecular polymers, providing high loss fatigue resistance. Simple, stylish, and easy to install.
