Where did you get the baffle material?



The baffle material is essentially 1" polyester couch stuffing.
You can find it at any material store quite cheaply. My wife used it to make dog beds quite recently.
If you pop off the driver from your sub, you will see exactly what it is. Just take a small snip off with some scissors if you need a sample.
In reply to:

Did you stuff it all the way through the port or just at the inner orifice?



The material was covered over the port ends on the inside, NOT stuffed into the tube. That would only cause the material to be pulled and pushed in and out as the driver moves sucking air.
In reply to:

Couldn't I just stuff the ports from the outside without opening the cabinet?



No, not really.
Taking off the driver is not difficult. Use a hex key (Allen key) to take out the bolts and then just handle the driver by its edges and stiff basket.

I've heard mine bark like a dog a couple of times - is that port chuff?



JohnK gave a definition of port chuff somewhere in this thread. The noise is an audible chuffing which i've also described as a flupping farty noise. Try blowing air out your mouth while leaving your lips really loose and then imagine that noise a bit lower in tone and it comes pretty close.
Does that help any?

Try out the Lord of the Rings scene i mentioned. If you turn up your sub to 40 or 50% you should be able to make it chuff (but not necessarily depending on your system settings).
