GTW 11204 D

12.0” Diameter | 4-layer Voice Coil with Aluminium Former


A piece of dual voice coil 12.0” woofer made of the vented pole piece and bumped back plate. GTW 11204 D is a dual voice coil speaker offers wiring flexibility with its two voice coils. It allows single speaker to output both stereo channels through one speaker, creating a stereo sound from a single speaker location.

A woofer is a speaker in your system that handles low-frequency audio signals. The GTW 11204 D offers a frequency range of 32-800 Hz, which will improve your listening experience when playing your favourite song.

Your GTW 11204 D’s capability to convert power (watts) into volume is indicated by its sensitivity rating (decibels). Your speakers' volume will increase as the sensitivity rating rises up to 82 dB.

Impedance is a measurement of a woofer’s voice coil's resistance to the amplifier-supplied audio current. GTW 11204 D has a 4 ohm resistance, thus the music it produces will be fascinating.
