LF Cast Chassis / Neo

NTR12-3018D

Features

12" neodymium woofer oers 350Wrms (AES standard) power handling and 98dB

sensitivity

3" high temperature Inside/Outside voice coil eciently 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 ecient 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.
