Mounted these bad boys in between two sets of 8" tubbies on my tower, at first when I turned it on I was like " they aren't that much louder than the 8s" so I climbed out of the boat and walked to the back, still not that impressed, so I turned around, walked to the backyard to kick the dog, well a song came on that my wife liked and she turned it up and "HOLY COW" they came alive! way louder than the 8s and clear as could be, they were more comparable to a dj speaker! the volume carried for ever and you could hear'em 2 blocks over (from what a not so impressed neighbor told me) I'm very happy with them and gonna get the 8" compressions next summer!
