This pair of Pioneer G-Series 6-1/2 in. 300-Watt 2-Way Coaxial Speakers is an excellent, entry-level choice to replace a bad set of factory 6-1/2 in. speakers. Their two-way design handles 300 watts max. power (40 watts nominal) and feature Pioneer’s extremely strong and lightweight Injected Molded Polypropylene (IMPP) composite cone woofers for improved sensitivity and reduced distortion. These full-mesh-grille speakers also have Progressive Flex Suspension System Spider to increase vocal and bass performance..
