Lowest Profile Good Sounding Tower Speaker?

This will probably start a war, but what good sounding tower speaker out there has the lowest profile when mounted on the tower? I have a 2008 SAN 210 with the titan tower and it sits kind of low. And no, I don't want to mount them above the tower as I'm not a big fan of that look. Also, when I say good sounding, I mean I want them to be clear riding at 80'+...I'm not so concerned about the sound inside the boat.

I've heard of NVS, Wetsounds and Exile. Which of these have the lowest profile? Are there any other brands out there you would recommend? Thanks a lot!
