Designed for Spaces Where Traditional Sized Woofers Will Not Fit


The Power T1S2-12 is a slimline 12" subwoofer designed for spaces where traditional sized woofers will not fit. Features a single 2-ohm voice coil for simplified wiring configurations.

Need bass but don't have a lot of space?  How about more power handling than your average shallow subwoofer?  Well, the T1 "Slimline" subwoofers are not your average shallow, in fact, they have been painstakingly designed to near exact performance characteristics of traditional sized Power T1 subwoofers you're already familiar with.


We're calling these "slim" subwoofers because they don't take a lot of depth and offer bass response similar to a traditional sized model.  How can this be true?  Well, let's just say the Wizards-of-Fos engineered an ingenious slotted voice coil assembly that exhibits long excursion travel.  Don't worry, you don't need to understand it, you just have to listen to how awesome they sound!
