Name: SELENIUM High Power 18” Professional Subwoofer, 1600 Watts Continuous
Model Number: 18SWS800

 The 18SWS800 is a high power 18” professional subwoofer
specially designed to reproduce sound at the very low end of the audio
spectrum.This new design is capable of handling up to 1,600 Watts
Continous Music.
A bumped and undercut T-yoke assures a minimum of magnetic
rectification (off centering) and a compatible maximum displacement.
The magnet assembly was designed with the assistance of a Finite
Element Analysis (FEA) software in order to ensure optimization.
The 18SWS800 employs a 4” (100 mm) diameter 4-layer cooper
voice coil using over 80 grams of cooper. This is wound in a fiberglass
former, twice the thickness of typical formers, to drive the moving
assembly with great rigidity.
A non-pressed long fiber pulp cone has the necessary stiffness to
withstand the tremendous accelerating forces involved and is properly
centered by two counteracting polycotton fiber spiders.
An triple cooling system consisting of a large diameter center hole
surrounded by six smaller holes (directly cooling the gap) and six frame
windows (cooling the air trapped between the two spiders) are
responsible for an efficient heat transfer mechanism.
A highly reinforced aluminum injected frame is effective in
absorbing mechanical shocks and acts as a heat sink without interfering
with the magnetic field.
