I guess this idea is out of the question?

I just bought two extra large foam rubber mouse pads and used silicone adhesive to glue them to the outer fairing, directly behind the speakers. These pads are about 1/4" thick and very flexible. They contour to the curves of the fairing very well.

http://www.officedepot.com/a/product...a-Large-Mouse/

These things are big (13.3" x 13.3"), a little trimming to fit and they look like they were made for the fairing. I should have the fairing back together tonight. I am hoping for an even better sound than I have now.

I was told by a friend with many years in the audio business that this was all that I needed to do. He says that the foam rubber behind the speaker soakes up and dissipates the presssure wave from the back of the speaker. This helps prevent bass distortion, cleaning up the bass.

Thanks troop, I'm going to try the male side of Velcro around the speakers and see if it holds. I did this to 6" PVC speaker cans that I made for my golf cart and its incredible the depth it creates.

....but I used one of those mats for in front of kitchen sink. Bought it at Costco for about $15.

Been there done that -- Worth it. Reduced the resonance in the fairing quite a bit.

Are you going to notice a huge difference in sound on the highway? No. You'll probably notice more listening to talk radio than with music. But I wouldn't consider it a waste in any case.

It's definitely worth it, but was it necessary to line the entire inner fairing? My understanding was that a square attached directly behind the speakers was sufficient. No?

First, IIRC John Scrip is an audio engineer and has a blog with useful info.

Second, I'd you go to Dynamat's website you'll see a product called Dynaxorb and am explanation of what it does. Dynamat's calls it a backwave that's created behind the speaker by the back and forth movement of the woofer cone. Dynaxorb and /or polyfil disperse the backwave so the sound from the speaker is not compromised.

You can feel the difference in the reduction of the backwave by doing a before and after test--just place your hand on the outer fairing and play some tunes. After installing Dynaxorb or polyfil, play the same tunes and you'll notice much less vibration

Apologies for the typos--pita type on the iPhone.

I did mine and it worked great. It acually pushed the sound our through the speakers much better. I was getting a rattle when I cranked it up...not any more. I would do it. It's sticky to work with though...
