Celestion NTR08-2011D 8" Neodymium Woofer 8 Ohm
Celestion NTR08-2011D 8" Neodymium Woofer 8 Ohm
The neodymium NTR08-2011D 8", from Celestion, incorporates a 2" copper voice coil, and a copper-sleeved pole for reduced inductance. An octagonal chassis profile is great for line array applications, while the M-roll cloth surround allows for progressive excursion control, and generates a smooth frequency response. Intelligent heat management built into the motor assembly and chassis enables reduced thermal compression.
