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!
