FTR18-4080HDX 1000W 8ohm LF Ferrite

Caratteristiche

- 18" ferrite subwoofer provides 1000Wrms (AES standard) power handling and a frequency response of 30Hz-2500Hz

- 4" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression

- Double suspension and a "multi-roll" surround provide exceptional linearity at extremes of cone excursion

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

- Less than 10kg - very low weight for this product class

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)Continuous Power Handling is defined as 3dB greater than the AES rating.

(3)Measured on axis at 1W, 1m in 2pi anechoic environment.

(4)Xmax derived from: (voice coil winding width-gap depth)/2.

(5)Small signal parameters measured after unit subjected to pre-conditioning signal.
