I have the J&M speakers in my 2011 SE Ultra and a buddy has the Boom speakers in his 2010 SE Ultra. We were sitting at the hotel with some friends and decided to see which speakers were better. Since we both have xm radio we used the same station. I played my radio for about a half an hour, and then my friend played his. Most of the guys with us thought the J&M speakers sounded a little better. At 75 mph with a full face helmet, I can hear the music clearly at half volume. At slower speeds I lower the volume. I think it's a great set-up.
