Rev 10s

So I'm throwing a pair of Rev 10's in my boat with a syn4. My current inboats are just the basic rockford fosgates, and no sub. I'm planning on buying a new boat after summer, so I'm just doing the towers for now. My question is how do they sound all around? I know they rock when up loud, but how are they for just chilling, how's the midbass at lower levels, and will they help my system sound better when I'm not trying to throw to the rider?
