Peerless by Tymphany TC9FD18-08 3-1/2″ Full Range Paper Cone Woofer



This TC family 3.5 inch 8 ohm full-range driver,with ferrite magnet, paper cone, rubber surround, and plastic basket with front sealing gasket, is designed to be a cost-effective high performance full range driver. The cone utilizes Tymphany-patented PentaCut NRSC cone technology to help dampen and control cone resonances, optimizing the listening experience. The motor contains a copper cap to lower inductance and distortion. The product was designed with portable and compact applications in mind.
