I found some polyfill material at my friend's dorm room that he was getting rid of, and I took some of it and used it to line the walls of my 10" ported sub. I have noticed quite a change in the character of the bass that comes out of the sub. First off, the big boomyness that I did not like has nearly vanished. Secondly, I have noticed a dramatic increase in the amount of what I call "head bass", which is bass that is stout and fat and sounds like it's coming from inside your head. the sub sounds like it has the potential to do a lot more eathmoving, almost like another one of my friends' dual Titanic 12" woofers. (I am in a college dorm, and I happened to get placed on the floor with all the hi-fi freaks, so that explains the speakers)
Bam,
Good for you.
Sounds like you damped some of those standing waves inside the box. The "Head Bass" as you call it, I suspect would have made the music sound "hollow". Like you're singing with your head inside a cardboard box.

Or possibly some standing wave with the room.
At my church, the rooms are very functional--they're made of painted cinderblocks, square, cube actually.... the elders all meet in one little room, and since the harmonics of people's voices tend to converge on a specific set of frequencies when you're having an agreeable conversation (as we usually do) you get this lovely standing wave, and any time anyone says anything, it feels like your eardrums are going to trade places...
Low bass does this. I tend to like my bass with a very slight low cut from 60-30hz, and low output below 30hz, and maybe a bump around 70-80hz for that extra "punch" from that reigon. I've found that if I place myself in certain parts of the room and the speakers beside me, I can actually make myself lose balance (!) just by listening to the right tones.

Actually, the "head bass" I'm describing is the sound of standing in front of the bass bins at a rock concert. It gives my head a pressurized feeling to it. It seems very deep and moves with the music, so it's not the objectionable 60-80Hz boomyness that my sub used to suffer terribly from. It used to sound like the sub was a cardboard box booming at those frequencies, and now it sounds like the room is the box. I guess the old boomy bass could kind of be called "head bass" as well but this is much deeper than that. I can definitely tell the tuning frequency of the box has shifted downwards. The sub now integrates much better with the main speakers as well. Just goes to show what a little stuffing will do.
