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.
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.
