On the surface, if you want stereo sound on your bike, this looks promising. I just wonder where you can go to hear one in action, for $500 or more, it better be the cat's meow. That center mount system looked pretty good but our gages are in the way of that type mount. Definitely something to think about, thanks for the link.
Alright, now I'm SUPERCHARGED!
I'm still a fan of ear monitors. Custom fit to your ears (inside the second bend) and they cut the outside ambient noise by 25 db. Enough to easily hear music or conversation but still they allow you to hear some s noise like horns and it makes HD pipes almost bearable.
They do sell ear phones that are like ear plugs but with speakers in them. They concel out noise like a plug so you can hear your music.
If you don't wear a helmet Bose has a nice pair of head phones that are noise canceling, I see people with then all the time on planes.
My Son is being trained as Rider Coach for MSF and one of the guys there in Detroit has them set up on his Road King and my Son says they sound pretty good and are pretty loud I will know this weekend as I am going to see him Graduate and check them out I will post the findings.
