I have the Wetsounds. I "thought" I was going to go inexpensive originally and went to a dealer in town to compare the PRO-80's vs a myriad of others. I thought the Wetsounds projected better and were cleaner than everything else they had in stock. I did save money on the amps and install by doing it myself. I could not be happier. The only thing I am bummed about is the way were ripped off our summer here in Utawh. Sure, a lot of people have them, but they are NOT as common as you would think they are. After all, they cost a pretty penny.
IMHO, to choose the right speaker, you have to listen to it. You also have to balance cost vs sound quality (and sound quality is very subjective). What sounds good to me may be crap to you, so go listen to everything you are even thinking of buying. The final factor will be how good it looks on the boat. You don't want something on your boat that makes it look bad, but then again, how good it looks is also subjective!! LOL!
Good luck shopping!
