This pair of Pioneer G-Series 5-1/4 in. 250-Watt 2-Way Coaxial Speakers is an excellent, entry-level choice to replace a bad set of factory 5-1/4 in. speakers. Their two-way design handles 250 watts maximum power (35 watts nominal) and feature Pioneer’s extremely strong and lightweight Injected Molded Polypropylene (IMPP) with MICA composite cone woofers for improved sensitivity and reduced distortion. These speakers also have Progressive Flex Suspension System Spider to increase vocal and bass performance..
