Product Info

This TC family 3.5 inch 4 ohm full-range driver,with ferrite magnet, paper cone, fabric surround and steel basket, 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 Pro column and other high sensitivity full range applications in mind.
