4” 2-Way Coaxial Speaker with Grille

DS18’s S40 is a compact 2-way coaxial speaker that brings DS18’s signature clarity in a form factor that fits nearly anywhere.

Performance in a 4-Inch Frame
With 40W RMS (120W MAX), the S40 is ideal for replacing factory speakers or building out a multi-speaker system. The integrated mylar tweeter delivers smooth high frequencies, while the woofer handles mids with power. The voice coil assembly includes ASV and EISV components for thermal stability and durability, even at louder volumes.

Tuned to Stay Tight
The S40 maintains tight response from 80Hz to 20kHz. Its mechanical design—featuring a rubber surround, black matte steel basket, and a barium ferrite magnet—helps control distortion while preserving output in small enclosures or OEM locations.

Built to Fit, Ready to Play
With a mounting depth of just 1.67", the S40 installs easily into doors, dashboards, and other tight spaces. It comes with grilles included and is ready to drop into your system without needing custom fabrication.

Make the upgrade and experience the DS18 Difference for yourself!
