Dynamat in the fairing is pretty much worthless. It's good for making the fairing weigh a ton and putting unneeded stress on the fairing screws IMO. The Poly-fil actually serves a purpose and weighs nothing.

 

Well,I for one would surely like to know what exactly is polyfil(not very bright) and how do you wrap the speakers with them properly.Pictures would be great.

 

polyfil is a material most widely used in pillows and blankets but many years ago found it's way into the audio world as acoustical shaping material. In other words it has the ability to shape a sound wave to refract (not reflect) movement of that sound wave to allow large speakers to be put in small sealed areas (mostly subwoofers) but also allows the controlling of mid to low frequencies where smaller speakers are installed into larger open air environments.

Now in non-technical terms. It tightens up sloppy bass response when used properly.

 

I get a better picture now.It's the same stuff that you use to filter the water in an aquarium.How do you suggest we get it all snugged up?do you some sticky tape or something.btw,great pictures and thank you so much for the awesome info

 

12" x 12" squares 3 thin layers. wrap tightly around speaker. It ain't going anywhere.

 

What is the easiest way to rid of that dynamat? My hands are sore from trying to remove just a patch...

 

 

if you used the thick polyfil, only 1 layer is needed. too much of this stuff will hamper the speakers ability to breath properly.

 

good luck with that! lol.. I would just leave it in there. It doesn't hurt anything as far as audio is concerned. my point was it's useless for dampening sound for acoustical reasons.

 

sounds crazy, I had the same issue. swapped from a 3" shield to a 7", now its like a concert hall when riding..I enjoy the money spent on everything now.
