Dont have the 4s, but have the 2s and are very pleased with them. I just didnt want to spend that much money on the speakers or have that much extra weight up there
Brooks, You never got back to me.. Is there too much weight with your setup? When you pull a wakeboarder, does the tower flex much or make a lot of noise?
I have them on my swoop tower, look and sound good, but the extra weight makes the tower flex a little bit in rough water. I believe they weigh 33 pounds a piece, although it adds extra ballast too I guess.
