Looking to buy some Rev10's this Black Friday and my boat is still getting built. Anyone know what setup is best? I'm planning on drilling a hole in the tower tube and pulling the wires down into the clamp so it's completely hidden instead of buying the mount Moomba sells for the flat welded piece that leaves the wires exposed. Just looking to see if I need the ability to swivel the speakers to get them facing straight back or if the tower is straight enough.

Thanks
