That's one hell of a port //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif

look just like the one i built for my DD 3515

yeah they are actually pretty easy... just use the tutorial

look just like the one i built for my DD 3515

nice. how did it sound?

I will read into it, I have never even attempted it...

very nice enclosure! i built one for my sundown e8s and love it.

I noticed you have it on a dolly to move it...haha...i bet that bish is heavy....cuz the one i built is only a lil over one cube and it's heavy as hell.

You're not supposed to stuff it?

lol like the lazyness with the jigsaw?

Lol, barely even noticed it

its really not hard at all. yeah its heavy as hell. you dont need to stuff it. its just like adding polyfill to a sealed box. it makes the sub think the port is longer. so if you cant quite get the length you need, you can add polyfill

That's not true actually. Adding polyfil doesn't affect the effective line length. It will help dampen the response and smooth out upper harmonics. Transmission lines will have an oscillating higher frequency response with peaks and valleys. Adding damping to the line will help average those peaks and valleys and reduce the upper order harmonics and thus lowering distortion and increasing sound quality. Stuffing too much will have negative results though that could leave you with a loss in output and low frequency extension. Damping will also reduce output around resonance as well. It will also help flatten your impedance curve and draw the two peaks together to make one low Q peak.

Adding polyfil to a line that is too short will not help correct the problem.
