S-3502 3.5″ Coaxial OEM Speakers | Clear, Crisp Sound

Bring clear, crisp sound back to your car with the S-3502 3.5″ full-range coaxial speakers, an easy OEM upgrade supplied and expertly fitted by Safe and Sound, the vehicle audio and security specialists with over 30 years’ experience. A simple drop-in upgrade Factory speakers fade over time and rarely do your music justice. The S-3502 is designed as a drop-in replacement for most standard 3.5″ speaker locations, so you can upgrade the sound without cutting, drilling or major modification. It is one of the most cost-effective ways to make your existing system sound noticeably better. Crisp highs and smooth mids Unlike a basic single-cone speaker, the S-3502 is a true 2-way coaxial. A dedicated 0.5″ PEI dome tweeter with a neodymium magnet and SEL (Sound Expander Lens) ring adds clarity and a wider spread to the high frequencies, while a DDC-coated 2-layer paper cone keeps the mid-range smooth and detailed. The result is a clear, balanced sound from the same head unit and wiring. Designed to fit almost anywhere The S-3502 uses a zero-protrusion tweeter design and a shallow 1.5″ mounting depth, so it fits neatly into the tight dash and door openings that 3.5″ speakers usually live in, across a wide range of vehicles. An EFF (Efficient Flux Field) motor structure and a rigid tooled basket keep the design efficient and solid, and the speakers are supplied as a pair. Drop-in OEM replacement – fits most standard 3.5″ locations. 2-way coaxial with PEI tweeter – clearer, more detailed highs. Zero-protrusion, shallow 1.5″ mount – fits tight openings in most vehicles. DDC-coated paper cone – smooth, clean mid-range.
