Default Symptoms of Overstuffing enclosures?

What are the symptoms of overstuffing a well braced cabinet?

Given that the stuffing still allows free movement of the drivers.

Loss of bass.

Increase in even order harmonic distortion.

In combination, an ill-defined "stuffy" sounding bass.

This is good news! I'll remove the eggcrate stuffing from most of the interior of my Kit 281's tonite, and only stuff them with the recommended amount.

Hopefully, this will improve the bass/midbass.


Thanks for the reply!

I'd recommend measuring the impedance before and after, just to see if you've hit the target Q that you're after.

Sadly, I have no actual equipment for measuring anything, except for a radioshack SPL meter for sound level calibration...

It has instructions and doesnt require any special hardware to do it

Tore out all of the eggcrate. I'm not going to make any judgement until I listen to them for a while.

Just make sure you don't go too far in the other direction; at least having the walls lined is a good idea. Then you can vary the amount to hit the target response- or please your ear.

I used the exact abount of polyfill that the plans called for. 6 oz behind each woofer, and, 12 oz in the bottom chamber.
