Installation and Sound to Suit Any Car

TS-G1020S speakers are excellent choices to replace a bad set of factory 4" speakers. Their two-way design handles 210 watts max. power (30 watts nominal) and features Pioneer’s extremely strong and lightweight Injected Molded Polypropylene™ (IMPP) with MICA composite cone woofer for improved sensitivity and reduced distortion.

You don't get just basic, run-of-the-mill features either. The conex damper delivers higher power handling and deeper bass, and the 1-3/16" Balanced dome tweeter reproduces highs with great performance and musicality.

These speakers are designed with a shallow mounting depth for easy install into a wide variety of vehicles. Speaker grilles are not included.

P.F.S.S. Spider

Progressive Flex Suspension System supports the voice coil effectively by dampening the large cone vibration and enhancing linearity of sound reproduction. Its soft part makes movement smooth and reproduces clear sound and at excessive input, its hard part controls excessive vibration and prevents movement error.
