Alright how many of you use polyfill in your ported enclosures when volume and tuning are built to avg recommended spec?

EDIT: As per request I'll add more detail.

For daily bumpin, for great lows, overall greatest sq, and maximum boom factor inside and outside car!

 
I said in avg recommended size and tuning, that's not enough? Ok, I'll add some info.
My post still stands. And really, it's a cheap and easy mod that you can easily do yourself and make your own final conclusions for. If I had a choice of either following blindly what some forum randoms had to to say or going out and making my own decision based on experience, I would choose myself every time.

 
I have used polyfill in ported enclosures...

with a thin layer on all inner pannel surfaces there is

a very small audiable difference in SQ..

too much polyfill will effect the inner cf3 and alter tunning

See, look it all the nice advice and link in the replies. That's very helpful!

If you soley relied on your own experience, why bother even being on a forum. Isn't one of the purposes of a forum to utilize the experience of others?

That said of course I'm going to draw my own conclusions, it's just nice to see what's common practice if there is any.

I would just try with and without but since I don't know what fasteners to use with my sub. (Unresolved in another thread - First they says tnuts, then they say tnuts are bad - then threaded inserts - then just wood screws). I don't want to put the sub on and take it off a number of times. Possibility of extra holes and/or destroying air tight seal for sub on the my first slot port box build that I spent forever designing, building, and carpeting!

Not trying to argue just showing my viewpoint. BTW i think you usually give awesome advice Immacomputer.

 
I can't count how many times I have mounted and unmounted my sub with wood screws in the same enclosure without harmful effects.

Your poll does **** as it doesn't include many options. I have put polyfil in ported enclosures and I have chosen to leave it out. It depends on my application and in this application: "daily bumpin, for great lows, overall greatest sq, and maximum boom factor," I can see times when I would use it and when I would not but it needs specific details.

I have to remove my sub frequently for spl testing and with it being square I can't rotate it. I've found that threads in the wood will last longer when tightening the screws by hand.

Alright, that's good I'll just use screws then. They've worked fine for me in wood but I was just afraid the mdf might act a little different. Guess not.

Ok, i see what you are saying. When I get the sub (hopefully tomorow) I'll listen to it without polyfill and see how it sounds.

Yes, I did do them by hand on the only two subs i have ever installed in my life. I figured it would be better by hand.
