It is very compact so you are not going to vibrate your neighbors windows

Again, it is not windows shaker but much better than 85hz and will void your warranty on the subwoofer.

Loads of extra kick for me, wasn't looking to blow out the windows, just add some bass is all, and it delivers perfectly

Like some of the other reviews this unit will not vibrate your windows but the bike doesn't have windows

No, you're not going to win any window-shaking contests, but this thing hits MUCH harder than I'd think it could

While this powered subwoofer wont rattle your windows, it will rattle your side mirrors and will produce bass that you and your passengers can feel

Now it won’t rattle the windows or shake your mirror
