NTR15-3018E 450W 8ohm LF Neodimio

Caratteristiche

- 15" neodymium woofer offers 450Wrms (AES standard) power handling and 98dB sensitivity

- 3" edgewound voice coil for higher efficiency and excellent distortion control

- "M-Roll" surround provides progressive excursion control, yielding a smooth response even at extremes of frequency range

- Extremely lightweight design combined with a highly efficient magnet assembly results in exceptional power-to-weight ratio

- Intelligent heat management in both chassis and magnet assembly design further minimizes distortion

Note

(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 2pi 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.
