Designed for very high SPL applications where precise 90° conical coverage in a compact coaxial system is required
- Ideal for surround systems in medium to large cinema rooms for immersive digital audio formats
- 1250 W continuous program power LF with 4" edge wound ribbon wire VC
- Extremely linear response
- Dual magnet design with independent magnetic gaps eliminates flux modulation and dramatically reduces intermodulation distortion in HF range
- 3" HF driver diaphragm made from proprietary hardened aerospace grade aluminum alloy with highest tensile strength to weight ratio and superior long term fatigue resistance
- Heat stabilized polymer suspension ensures low distortion at high peak SPL and long term stability in most demanding applications
- High performance edge-wound ribbon wire voice coils for maximum reliability
- High transparency and resolution
- Optional premium XO
- Optional matching 70V transformer
- HF driver with 16 ohms impedance option
