Good and deep but not overpowering. I was going to go RcX but when I saw the monster squares I just had to go with them . . .
They look great! Especially the black with your two-tone black on the bike. I see you went with what looks like the Power Duals as well? I almost got the same ones but opted for the Oversized model. Hope they sound as good as you say yours does. Good riding!
