Celestion NTR12-3018D 12" Neodymium Woofer 8 Ohm
The neodymium NTR12-3018D 12", from Celestion, incorporates a 3" high-temperature, inside/outside, copper-voice coil to effectively dissipates heat, and prohibit sensitivity loss through thermal compression. Intelligent heat management built into the motor and chassis assembly for reduced thermal compression. An M-rolled cloth surround for progressive excursion control, generating a smooth frequency response.
