Voice Coil - The brains of the operation, directing the force from the magnet to push or pull based on the applied electrical signal.
Basket - Also referred to as the frame or chassis, this is the skeletal system of the speaker. Here to keep everything in its place.
Spider - Second part of the speakers suspension, connects the cone and voice coil to the basket and controls the travel of the cone assembly.
Surround - First part in the speakers suspension, attached to the cone to maintain the centering of the voice coil in the magnetic gap.
Magnet - The heart of speaker, creating the force to push and pull cone assembly. Size, material, and design may differ, depending on performance goals.

ANATOMY OF A SUBWOOFER
POWER subwoofers raise the bar with high power handling and bass that can rattle windows in the next town! Check out Century 2000 pricing.....
Cone - A.K.A the diaphragm, this is the voice of the speaker. Shape and material dramatically change tonality.
“For years, our Power Series subwoofers have garnered accolades from both our dealers and customers alike, and so we are excited to ship our updated Power Series subs for 2015,” said Jake Braaten, Rockford’s V.P. of product development & engineering. “As installs become more and more intricate and space limitations are more common, we’ve redesigned our Power Series subwoofer line to include slim-fit models that accommodate such applications. We were careful not to compromise performance, and even created a revolutionary design that delivers class leading performance.”
Braaten added that technical highlights that contribute to the Slim-Fit subs’ new performance characteristics include injection molded foam surround with VAST proprietary surround technique, encapsulating voice coil to former coupling technology (patent pending), high temperature energy neodymium motor structure, and proprietary split yoke pass thru motor structure (patent pending).
Variations in the anatomy of a subwoofer dramatically changes their performance characteristics. An increase in voicecoil size coupled with a stronger cone material yields a higher power handling and increased output. By combining quality materials with Rockford’s proprietary acoustic technologies, our subwoofer lineup is sure to meet your system’s demands.
