LF Cast Chassis / Neo
NTR12-3018D
Features
12" neodymium woofer oers 350Wrms (AES standard) power handling and 98dB
sensitivity
3" high temperature Inside/Outside voice coil eciently dissipates heat,
preventing sensitivity loss through thermal compression
"M-roll" surround provides progressive excursion control, yielding a
smooth response even at extremes of frequency range
Extremely lightweight design combined with a highly ecient magnet
assembly results in exceptional power-to-weight ratio
Intelligent heat management in both chassis and magnet assembly design
further minimises distortion
8 Ω Frequency Response
1. Tested for two hours using a continuous, band-limited pink noise signal as per AES standard. Power
calculated on minimum impedance. Loudspeaker tested in free air.
2. Measured on axis at 1W, 1m in 2 anechoic environment.
3. Xmax derived from: (voice coil winding width-gap depth)/2.
4. Small signal parameters measured after unit subjected to pre-conditioning signal.
