SEAS U22RNY/P H1657-04. Superb 8" 4 ohm woofer. High 94.50 dB Sensitivity. Prestige 8” Lower Midrange/Woofer with an injection moulded metal chassis, intended for ported designs.
Featuring a New Curv cone, a woven polypropylene with excellent internal damping together with perfectly matched moving parts gives a smooth, extended frequency response. Bumped back plate in the magnet system together with a high temperature voice coil wound on an aluminium voice coil former giving low distortion and high power handling capacity. A heavy copper ring below the T-shaped pole piece reduces non linear and modulation distortion.
The bullet shaped phase plug reduces compression due to temperature variations in the voice coil, avoids resonance problems which would occur in the volume between the dust cap and the pole piece and increases the long term power handling capacity.
An extremely stiff and stable injection moulded metal basket keeps the critical components in perfect alignment, and large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum.
