Thanks! You're on the list!


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 how it works, you just have to listen to how awesome they sound!

Greatest Shallow Mount

This is BY FAR the greatest shallow mount I’ve had. I’ve been trying shallows for a while now, looking for the best for my truck. I’ve tried the sundown sd-3 10 (great other than the odd noises that start to appear a couple weeks into use), skar ev10s and 12s, kicker comp rt10, infinity reference shallow, and JL tw3 10. This easily trumps all the others. Clean bass, but easily overpowering if that’s what you want. It handles more than enough power for what it is (I’m running a rockford r750-1d, which had 860rms on the birthsheet) and it’s handles almost all of it. Couldn’t be more impressed with this sub!
