Air Suspension Excursion Control System
Secret: Enjoy deep big bass from a small enclosure. In order to create a subwoofer that is three and a quarter inches deep, Pioneer had to develop revolutionary subwoofer technology. A traditional subwoofer uses the spider design to keep the voice coil of the speaker aligned while it moves. This type of set-up can become soft over time degrading the subwoofer’s performance. Pioneer created a patent-pending air suspension system that locks air between a main cone and a drive cone. The cones move together in unison, with the locked-in air behaving like a spring. The dual-cone structure is a spider-less design that maintains better sound linearity, and reliability even after many of hours of hard use. The pressure from the trapped air results in a consistent bass response across a wide frequency range. The result is a tight, precise movement with powerful and clean bass output.
Angled Push Terminals
Traditional subwoofer terminals are mounted horizontally or vertically. These mounts force
wires to be bent to fit which can be difficult if low gauge high performance wires are used. The Pioneer shallow subwoofer’s patent-pending, angled push terminals make it easy to connect speaker wires. The straighter connection saves space and makes installation easier.
Downfring Subwoofer Technology
By directing the subwoofer diaphragm downward, the TS-SWX251 radiates bass with superior efficiency for richer, deeper low-frequency sound regardless of the enclosure’s installed position. Thanks to its innovative enclosure design, the TS-SWX251 enclosure can be installed freely in the cabin or luggage area for optimal utilization of space. Compact space-saving dimensions make it easy to install the subwoofer in a variety of trucks- standard-cab, extended-cab, or crew-cab.
