Design: This woofer has a
five-sided polypropylene cone. This design stiffens the cone, resulting in lower
distortion and higher power handling.
Foamed Rubber Surround: The
foamed rubber surround provides high power handling, enhanced cone control and
flexibility. "Hash Marks" in the surround provide added stability.
P5 Center Cap: The five-sided
dust cap adds strength to the cone assembly.
Inner Cap: The inner cap at the
top of the voice coil former stabilizes the former's "roundness" and
strengthens the connection between the cone and the former.
Three-layer woven dampers provide enhanced cone control and have the lead wires
woven in to prevent shorting to the frame.
Voice Coil: The
four-layer, edge-wound voice coil provides plenty of copper to pass the current
necessary for high power reliability.
Binding Posts: The gold-plated
binding posts will accept bare wire, pin connectors, spade lugs and banana
plugs. The binding posts are spaced too far apart to accept dual banana plugs.
Enclosure Compatibility: This
woofer can provide extended bass in sealed and ported enclosures (please see the
"Enclosure Compatibility" section for more information on the
