| The B&C Speakers 8NDL51-16 is an efficient and lightweight cast frame 8" neodymium driver. Its ventilated voice coil gap ensures long term power handling and reduced power compression, and a copper cap on the pole piece reduces inductance and extends high frequency response. The 8NDL51-16 is highly recommended for compact 2-way speaker systems or as the midbass/midrange element in high-output 3-way and 4-way designs.
- Great for line arrays and horn loading
- Neodymium magnet assembly
- Ventilated voice coil gap for reduced power compression
- Inductance-reducing copper cap on pole piece extends HF response
- 2" copper voice coil on polyimide former
- 400 watts continuous program power capacity
- 65 - 3,000 Hz response
