The TS-351M is a 2-way coaxial 3-½" speaker. Its Injected Molded Polypropylene woofer cone stands up to the harsh in-car environment while providing natural sounding tonal qualities with an OPEN & SMOOTH transition to the polyetherimide Tweeter. The TS-351M is an A Series speaker.
All A series speakers share the OPEN & SMOOTH design concept and are voiced to sound great together.
