B&C 12CXN88 12-Inch Coaxial Driver - 500W RMS, 8 Ohm

The B&C 12CXN88 with larger voice coils for increased power handling. A significant increase in magnet mass also improves sensitivity and cone control, while integrating our latest compression driver technologies improves sound quality and durability in the HF as well. For high output applications where fidelity at maximum SPL is the primary concern, consider the 12CXN88, with 3.5-inch LF and 3-inch HF voice coils. Power handling has increased to 1000W, while also improving nearly every other parameter (including Xvar) relative to our established 3-inch coil CXN76 series.
