MP694 – 6 X 9” PRO FULL-RANGE CO-AX HORN SPEAKER
 
If you're looking for one of the best 6x9 speakers for your Harley Davidson, the MP694 by Diamond Audio is going to be one of the best options. The tweeter is not over-bearing and sounds great with the mid. The MP694 outperforms many other motorcycle speakers in a lot of different categories - midrange performance, tweeter performance, bass levels, etc. Not only are these 6x9 speakers superior in sound, they're water resistant speakers too.
