To Polyfill or not to Polyfill, that is the question?

Say you build a fiberglass enclosure exact to subwoofer specs, do you still place polyfill in the box?

Usually people say to use polyfill to make a box appear bigger to a sub....but this is not the case for me.

Will the polyfill eliminate standing waves? EDIT: Read up and saw standign waves in this frequency range are not an issue

To use Polyfill or not to use Polyfill? That is the question.

I have an IDQ10 v.2 d4 BTW and here are two images of the box.

Nice reply. I see you have nothing better to do than reply with useless chatter to up your post count or help you feel smarter
and i see you have noting better to do than making ANOTHER thread because no one gives a **** about what you asked.

Let me guess, since no one is replying a answer in this thread...your gonna make a 3rd asking the same thing right?

 
fwiw, i have a 10w6v2 and a JL spec sealed box. Called JL and asked specifically about polyfill and an enclosure built to spec...

JL response: we always recommend it...even when box is built to our exact spec. ~ 1lb per sq. ft.

Poly fill traps the rear wave of the speaker keeping it from reflecting back and hitting the cone. This reduces 2nd order and 3rd order distortion...

LOL - mine was a higher end model too - iirc deh-9300. Low mileage too, it was sitting around for year collecting dust.

One or two, they are still subwoofer outs and are mono summed signals from both left and right. Even the 2 RCA subwoofer pre-outs on the 2nd one...
