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
The W18E001 is a 6,5" cone driver developed for use as a high fidelity Woofer or Woofer/Midrange
unit. The extremely stiff, yet light cone and the acoustically transparent basket give tremendous bass
precision and midrange detail.
SPECIAL FEATURES:
Precision cast and surface treated magnesium cone coupled to a natural rubber surround showing no
sign of midrange (edge) resonances.
Magnet system with bumped back plate makes room for extreme coil excursions.
Heavy copper rings mounted above and below the T-shaped pole piece, to reduce non linear and
modulation distortion and increase overload margin.
Copper plating of the top and bottom plates and a solid copper phase plug, which enhance the
performance of the copper rings and improve heat conduction away from the pole piece.
Gold plated terminals mounted on a glass fibre reinforced plate to reduce contact resistance and improve
reliability.
Extremely stiff and stable injection moulded metal basket to keep the critical components in perfect
alignment. Large windows in the basket both above and below the spider to reduce sound reflexion, air
flow noise and cavity resonance to a minimum.
