Cannot stress Poly-Fil in sound bar enough

I just added poly fil to my soundbar, holy hell, what a difference. I thought just replacing the OEM speakers was huge, stuffing that soundbar was almost like I had a cheap sound system!

How have you guys stuffed your soundbar? Mine is in pretty packed near dome light but loose on edges, I am wondering if I should pack tight throughout, any thoughts?

Poly-fil works wonders. I used to use it in my subwoofer boxes back in my sound system days. I kinda packed them medium firm if that makes sense. Enough to kinda have to push the sub in as you go to screw it in.

Anybody want to give a short tutorial on how to do this for a moron like me? Sounds like a necessary mod, but I'm not exactly sure where to put the filler. Behind speakers? In front of speakers? Both? Contacting speaker cone? Help?

Your not a moron?! Just eager to learn things :-) Poly-fil should be placed behind the speaker inside of the speaker box. I don't recommend that it touches the cone since it could cause problems with the sound. The backside of the speaker has a "cage" so that will protect it from touch. Hope this helps.

I've always just cut upon an old pillow and pushed the stuffing in there. Works great.

Hey Bill!

Just remove one of the rear speakers and begin stuffing it in towards the dome light. As to the rest of your question, I am kind of wondering myself, I am not sure how tight to pack it. I didn't put too much around speakers, and it made a ginormous difference. Just want full potential, so hopefully someone chimes in.

This mod may have prevented me from buying a new deck for a few years at least!

Just pack it in so you have to slightly push the speaker down/up (whichever direction it has to go) to fasten the screws.

Bingo. Thank you for the perfect answer.

And your right, I can't be a moron.... If it is true that one learns from their mistakes, I must know an awfully lot about just about everything!

Great! So you really did mean that you stuffed the sound bar, not just the speakers on the sound bar.

Thanks.

Now to find an old pillow or something filled with poly-fill.....

Haha no problem! And believe me, I'd be a moron myself if I didn't learn from my mistakes. And I've made plenty of those in my short life I've already lived!

What about the dash speakers?

Is this the same white material you buy for pillows?

Sure is! You can get poly-fil for cheaper than you can a pillow. (I think) at a fabric store.

ha, I think the sound waves like the plush effect, maybe even moreso than regular non-plush poly fil

Guess I will go back in and put some more inside the soundbar.

I packed rear sub and two sound bar speakers with polyfill. I did not replace the stock Infinity speakers. Good news was it only took about an hour. Bad news was with the stock speakers the improvement in sound was only very modest.

Did it make a difference with the sub?

I replaced my head, added a powered sub, an replaced all four speakers with kickers. I am hoping this little cheap trick will help especially up front since there is really nothing there to help push the sound.

I would definitely give it a shot, it woke up the Polks in the soundbar.

Apparently it helps with sound imaging too.

I used this song to test before and after, Wowsa, what a difference, I am smiling

I never heard of this. Sounds almost like a bad joke, putting pillows behind your speakers....

But I guess it would be nice if someone could post some (simple) pictures to explain a wee bit better and a sound sample before and after would make it complete off course! However, I guess recording the sound would not really work...

Sound waves technically echo inside of the speaker box. Think of it as when you go to indoor concerts. The walls have the padded squares. This helps prevent/reduce echo and it also helps to enhance the acoustics.

Sound bar speakers, sub woofer done! Took 1 1/2 old pillows. Thanks guys!

After removing the cover to the sub, the speaker did not want to come out. I hooked the short 'el' end of a small Allen wench, held in vice-grips, into the rectangular opening in the bottom of the speaker frame, and it pulled out easily.
