+8 points for making the water dance
-10 points for playing Flo Rider. LOL
But on a serious note that's pretty cool for a Single 12 that's not even pointed at the side of the boat.
DISCLAMER: Making water Dance has NOTHING to do weather your boat is hitting hard or Not.
Some boat's have lots of flex in some areas and that Aid's or enhance's this effect.
also how your box is tuned can also have a effect,
Boat's that have lots of freeboard and span a distance between the floor and the top of the gunnal tend to have more flex. This can work like a Drum head.
My Nautique has a very Short distance "or span" between the floor and the gunnal and its built like a Tank. try pushing on the side and you get little to no flex. Trying to get that boat to do a "water show" is pretty hard.
Other boat's you push on the side of the hull and its like a trampoline!
Dan: No Issues. I have found it's tricky to predict weather your going to have them or not. Some installs have canceling issues written all over them right from the start. I had done another system that was close to this system and it had issues. We had to tune one box to a diffrent freq to sort the issues out. But now with Digital EQ's like the DSP and the New ARC EQ you can Time Delay and do alot of tweaking.
