Alpine SWT-10S4

Engineered To Fit And Sound Great In Your Truck

This SWT Truck Subwoofer combines the intense low-bass performance and ground-shaking output of the traditional Type-R subwoofers in a thin package optimized for extremely small enclosures.

Shallow Mounting Depth

The SWT 10” Truck Subwoofer has been engineered to offer more installation flexibility without sacrificing big output to build the ideal sound system for your truck. At 4-1/8” deep, these subs provide deep bass performance where it normally couldn’t fit in a truck. And the vented pole optimized for 4-1/8” deep box is the ideal enclosure size meaning great bass performance can fit just about anywhere in your truck.

More Excursion = More Output

The FEA-Optimized Motor Structure together with our revolutionary High-Amplitude Multi Roll (HAMR) Suspension Design gives the new SWT Truck Subwoofers the highest X-max and SPL output in its category.

The new SWT Truck Subwoofers deliver the best-in-class bass output, ultra-low distortion, and unparalleled sound quality. With a real world, measured 11mm of X-max, the SWT subwoofers perform like traditional models, yet fit in smaller spaces.

4 Unique Alpine Technologies

Radial Vented VC Heat Sink & Airflow Management System

Actively manages voice coil temperatures by forcing air directly across the heat sink system.

FEA Optimized Dual-Sided Machined CRC Motor Structure

Creates a symmetrical magnetic field with evenly distributed flux density to greatly reduce distortion, while further improving power handling and output.

FEA Optimized Injection Molded TPE Spider with Pass-Through Gap Design

Provides the mechanical clearance needed for over 50mm of peak-to-peak excursion, unleashing massive output potential from a small package

FEA Optimized HAMR Surround

The High-Amplitude Multi Roll Surround Design allows for extreme excursions without sacrificing valuable cone area. FEA Optimized for linearity and made with injection-molded Santoprene ®, the HAMR surround is a key part of the suspension system that provides accurate, distortion-free control at extreme excursions.
