Overall I am not very happy with these speakers. These are the new version of the NKA 169, which in my opinion were much better. The NKF 692's dont seem to sound as good. I have a pair of them in the front of my boat and a pair of the NKA's in the back. You can definitely tell the difference. Also, the metal grill over the tweeter started to rust within a few weeks and drip rust down the front of the speaker. Not sure why they changed the speaker design.
On another note, the speakers are still good compared to other marine speakers. if I didn't have the old ones, I might not have anything bad to say, other than the rust issue. I would rate the original NKA's with 5's all the way across.
