hey everyone, does anyone know if this is true: using pillow stuffing inside your sub box to slow down the air movement thus "tricking" the sub into thinking its in a larger area than it truly is.

i bought a kicker L5 a fewyears back and if i recall i thought it mentioned it in the owners manual.. hmm, maybe i just read it up someplace online too. i dont see how it can hurt anything but i didnt notice anything dramatically different from any other setup ive had. interesting idea however hah

Kicker, for as long as I can remember, has always recomended polyfill inside their enclosures. I don't know if it helps or not, but I've always had it in my enclosures. ------------- Kevin Pierson

Polyfill is the shizznit lol. It worked in many boxes I built.

polyfil works by creating a longer path for the air inside the enclosure to travel over, thus making the driver act as if in a larger enclosure. not much larger though, it only adds up to a 10% perceieved increase in space to the driver.

And in order to achieve that sound, about 40% of the airspace needs to be filled. Typically, that is about 1lb. for ever cubic foot of airspace in the box. But hey, that 10% "increase" might be just the thing one needs for the dreamy sound they wanted. Ganbatte ne! ~~~~~~~~ ps. Hi Kevin...

I know from experience that stuffing your box will give you a much richer sounding bass, much tighter. sounds cleaner. An empty box resonates, and you can hear it at the right frequencies.
I will always stuff my boxes, or line them with some padding, like 1/4" felt.

does this work in ported boxes as well as sealed? which would sound better with 4 10" kicker cvr's?

kicker's prefab enclosures have about 40% polyfil in them from factory... Its not terribly expensive so just try it out!!! The road to audio bliss is a long and expensive one....

If your ported just use the sheet batting and spray adhere it to the inner walls of the box. Sealed boxes, use the bulk fill and try not to let it plug any vents around the driver.

there are some pretty cheap options i buy a sound deadening material from jaycar at like $10 a bag which is enough for a box where my pillows cost like $50 :) it does give a better sound noticebly in the boxes ive built. im not entirely sure about the technical aspects but ive been told it makes the box appear bigger to the sound waves and removes/reduces any extra beats being produced by the backwards travel of the sub which gives you a nice tight sound. so it may not be ideal if you have cheap 15" subs and listen to hiphop :)
