Default Polyfill vs Speaker Baffles

I've seen the suggestion on the forums here to wrap the back of the speaker with polyfil to improve the sound quality.

How does that compare to speaker baffles?

speaker baffles were designed to be used as dust and rain covers in doors of vehicles. They do serve a purpose other than that and it's mainly to separate speakers in a combined enclosure such as putting 6x9s in the same enclosure as subwoofers to keep the sound waves from cancelling each other out.

With that said they can also be used to "contain" a speaker's sound waves or make an enclosure smaller.

Polyfil is a whole different beast and is used to trick a speaker into thinking it's in a more suitable enclosure for the speaker.

The only time I'd use baffles is when you have a large opening.

Im just wondering will polyfill absorb water? I certainly wouldn't want a wet sponge around my speakers.

The polyfill is a PITA to keep on the speaker. Any tips would be a big help. Thanks.

negative. It's a man made material that will not absorb water.

In a batwing fairing, you simply wrap the speaker tightly with polyfil then put the outer cap back on. The cap holds the polyfil in place.

In a Sharknose fairing, you'll need to secure the polyfil with zip ties to hold it in place.

Take a look at Beav's pics here. This is a Sharknose install but the principal is the same.

Default A pics worth a thousand words...

The pic now explains why I'm having such a tough time with getting the polyfil to stay. I purchased Polyfil that is more like a foam sheet.



The pics here look like light fluffy stuff like what's in a pillow...

I wonder if my contraption will work?

Haven't tried to put it together yet...

yeah I don't know what that is but it's not the rolled polyfil batting that I'm referring to. That looks more like a foam. I personally would remove it and get the batting type material to wrap the speakers in. Otherwise you'll need to trim some of that off to get the fairing cap back on.

Also the LOC80 in the pic needs to be rotated under that wiring harness as I feel it will be in the way of the inward curvature of the fairing cap. Under the harness should be perfectly fine.
