SQ and stuffing

[DAMIC]

Hi,

I am in process of changing the drivers in my 2 vented subs with newer Visaton TIW 250 8 OHM units. The current boxes give me net volume of 65l, which I would like to increase to about 80l.

So, I have two options, first: to slightly modify/enlarge the current boxes to desirable volume with no stuffing at all, and second, to put determined amount of polyfill , that will imitate bigger volume.

The subs will go up to 84Hz (LR/24dB, by EV Dx34a digital x-o).

Ia am ok with any option, but wonder which one would give better sound quality , smaller volume with stuffing or bigger, without.

Thank you in advance for any opinion.

I would estimate you're not going realize the same advantage from stuffing as you would increasing the box size by almost 1/4. I understand the stuffing can add a 'virtual' 10% to the volume

Thank’s a lot Weldon, you are right. Yesterday, I find some older posts written by Sreten and Svante that lead me to the conclusion that there is no substitute for pure volume.
