I looked at the Wetsounds, HSE Trident's, and the NVS extensively prior to my purchase.
The setups I listened to...
Two pro 485's - too bright
Two NVS 10-10's - to bright
Wetsounds Threesome - less bright, but still too much.
HSE Trident - the fullest sounding of the horn based systems. I didn't like the mounting, and the price seemed a little high compared to others.
Two NVS Addictions - didn't sound bright, but didn't sound full enough either.
Two Pro Eighty's - same as the Addictions, maybe a little less.
Four Wetsounds Pro Eighty's - Sounded great. Full, loud, and no brightness. The down side for me was the amount of space they take up on a smaller tower. Maybe you could try this setup prior to swapping out of Wetsounds completely.
I was on the fence trying to figure out what direction I was going to go when I talked to Duane. He asked me to demo the Tyrants and see what I thought. After trying them out, I have to say they were what I was looking for in a pro audio setup. Their very loud, very full, priced right, and relatively compact on a tower compared to other setups that produce the same sound.
One thing some people don't understand is the fact that no matter what you do with the pro audio systems, they are never going to sound good in the boat. They are designed for the rider. If great sound in the boat is what you want, you should look at the car audio tower setups.
Hope this helps.
