how tightly should it be packed in??

Thanks!

 

depends. try different things and see if you hear a difference.

 

depends on what??
I'm using two Pioneer shallow 10" subs in an ED-like box.

 

it's a trial-and-error process... you'll just need to put some in, then listen to it for a while, then add or remove some to adjust the sound...

the basic rule of thumb is ... the less you put in, the tighter the bass will be... the more you put in, the "boomier" it will sound...

you'll notice that the majority of the loudness/volume will move up and down the frequency range as you add or remove the poly-fil.

just keep adding or removing and you'll eventually find the right amount of poly-fil for the type of music that you listen to...

 

Cool... thanks for that info.
Not exactly as simple of an answer as I was hoping, but I guess it's the way it is,

There was some in there before, but judging from the sight of it, I didn't think it was enough... but I thought the speakers sounded fine how they were.

My only reason for wanting to adjust was that I've read that putting in the poly-fil "tricks" the speakers into thinking it's a larger box than it really is.....
Not sure if that means sound-wise or if it is better for the speaker, if the airspace happened to be a little less than the recommended volume... if that in itself is actually BAD for a speaker...

Thanks again.

 

I asked a guy in a shop and he said match the weight of the poli to the size of the box.....as a starting point.......in example box 1 cu then 1 lb of poly.......add and subtract as needed for liked sound......my boxes are .57cu each and they have little over 1/2lb poly in them.

 

That makes me feel a little better... like I have some frame of reference to go off of :D
Thanks, dudes.


Crappy thing is......... as I was screwing in the last screw of the second sub, I thought to myself, "damn... it would really suck if I slipped and ripped the sub's surround."

Sure enough, God hates me, and no more than THREE SECONDS after thinking that, that is exactly what happened.
I tore part of the surround on one of the subs. It still sounds fine, but I'm sure it's gonna spread with time.
So, I just ordered another one that should be here in a few days hopefully.

 

Did you tear the flexable excursion part or just the ring next tothe screw.......two of my subs are glued at the ring to keep them sealed as they peeled up......gonna make a aluminum ring to go over them to pin it down so it does not spread.

 

It tore part of the outer ring on the woofer... the part that flexes as the speaker hits.

 

thats a bummer.......yeah the sub unless restorable is gonna not last with it like that.......must be some materail though that can slow it down.....not sure what though

I know for our guitar and bass speakers we often used superglue and made a clean repair that worked fine.........but we also did not worry about distortion........the more the better in that case.......

somebody here must have a good product that can fix it ..........

I know several companies repair/refurbish speakers........but I bet in most cases a new one is gonna be more benificial.

 

that sucks. i did that to one of my door speakers before. it is so agravating. hopefully u get it fixed
