Need help choosing 6.5 inch speakers!!

I am taking down my west marine xxl speakers(4of them) because the weight on the tower is just too much. The sway going over rollers is concerning me. I am going to use 6.5 inch coax speakers in some custom cans. What brand is going to be the best sounding at high volumes and be able to hold up to the power. I have plenty of amp power, so that is not a concern. Just looking for brand names such as Focal, Mb quart etc. Thanks for the help
