WOOFER
Response curve recorded in anechoic chamber (Free-field, 4 pi radiation) with 0.5m microphone distance.
The loudspeaker is mounted in a closed box of 12 l net. volume
G18RNX/P
The G18RNX/P is an 18 cm (6,5'') cone driver, developed for use as a long
throw high fidelity woofer or woofer/midrange unit.
The light weight copper clad aluminium voice coil wire, a composite fibre glass
cone, a bullet shaped phase plug and a natural rubber surround are carefully
matched to each other, resulting in a smooth frequency response, and a clear,
precise reproduction of the critical midrange area.
The large magnet system gives good transient response, and the bumped back
plate together with the very long voice coil allows room for extreme coil
excursion with low distortion.
The extremely stiff and stable injection moulded metal basket, keeps the
critical components in perfect alignment. Large windows in the basket both
above and below the spider reduce sound reflection, air flow noise and cavity
resonance to a minimum.
