SWT-10S4

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.

Alpine SWT-10S4

Sound great in my sealed enclosure. Have 2 in my regular cab Sierra.

Great subs for the money

These subs are great for the cost of them. They hit harder than I expected for being shallow. My wife can hear me pulling into the driveway when she is inside with the tv on! I can't speak for their durability, but they look to be built really well. I would definitely recommend these.

Great for the price!

I built a box specific to the sealed box dimensions it requires. put it in my gladiator, and I am very happy with it. exactly what I needed for the cost. Yes, could I spend more and get more, sure. but this was exactly what I wanted.

Not worth it

Have 2 in a 2012 Dodge Ram hooked up CORRECTLY, nice to have them under the seat and out of the way. They do not BANG hard. If you buy the right door speakers and spend the same amount you'll get the same bang.

Pretty good for truck subwoofers

These were put in a 2017 GMC Elevation and they sounds pretty darn good! Their not completely shallow which helps keep some more depth I feel like but made a nice addition to the truck!
