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.
