Alpine SWT-10S4 10" SWT Series Single 4-ohm Shallow Mount Truck Subwoofer

The Alpine SWT-10S4 10-inch Truck Subwoofer is specifically engineered to deliver high-output bass in the restricted cabin spaces of pickup trucks. Designed to fit where traditional subwoofers cannot, it combines a shallow mounting profile with the heavy-hitting performance characteristics expected from Alpine. With a shallow mounting depth of just 4-1/8 inches, this subwoofer allows for compact enclosures that fit into narrow crevices without sacrificing deep bass performance.

This subwoofer features Alpine's revolutionary High-Amplitude Multi Roll (HAMR) Surround Design, which allows for extreme excursions without sacrificing valuable cone area. The FEA-Optimized Motor Structure, combined with the HAMR Surround, gives the SWT Truck Subwoofers the highest X-max and SPL output in its category, delivering best-in-class bass output, ultra-low distortion, and unparalleled sound quality. A real-world measured 11mm of X-max ensures powerful performance from a compact size.

The SWT-10S4 incorporates four unique Alpine technologies to optimize performance. These include a Radial Vented VC Heat Sink & Airflow Management System that actively manages voice coil temperatures, an FEA Optimized Dual-Sided Machined CRC Motor Structure for a symmetrical magnetic field and reduced distortion, an FEA Optimized Injection Molded TPE Spider with Pass-Through Gap Design for mechanical clearance and massive output, and the FEA Optimized HAMR Surround made with injection-molded Santoprene® for accurate, distortion-free control at extreme excursions.
