I finally had a chance to hear these the other day and I was very, very impressed.
I installed them in my buddies boat paired to an Alpine PDX-F6 and they did not disappoint. Actually, they sounded better than I figured they would and were incredibly loud. They were very crisp and clear even at high volumes and handled the power well without the tones bleeding into each other and distorting.
Thought I'd throw a little FYI FWIW
out there for anyone looking for some nice in boats.
PS. The only reason I don't have them in my boat is because I currently have seperates in and don't know what to do with the tweeter holes
