For the first time I am at a loss for words. From the moment you pick this sub up you will realize what a sub should feel like. There is nothing negative I can say, no bad comment, and no regrets for getting two of these. I listened to several bass heavy songs and all I can say is a quote, " T1 subs thump bass period."
I’ve got a P1 sub from Rockford before. I’m now trying their more expensive options, especially the T1s. This 15 inch T1 sub is so powerful. Really shake things up with its power output. So much better than old RF sub. Perfect upgrade to have with the same brand.
