Speaker stuffing: How to? (hlp plz)

[Wikkid]

I'd greatly appreciate knowledge/advice on box stuffing.

The situation is this:
Ported box using HiVi F10 woofs.
Box lined with "eggcrate" or textured bedding foam.
LoPass XO (if it matters) is around 350hz.

Problem is:
The sound is muddy/boomy with nastily smeared honky/bonky
lower mid (broadly around the XO region).
Boomy/honky/one-notey midbass and below.

This woof has highish Q for a ported box woofer... and it sounds like it.
QTS=.39 QMS=2.26 QES=.48

I need to tame it.
Woof is also a tad higher eff than the mid its crossed to.
(so I don't mind loosing a db or 2)

On first try at taming it, I OVERstuffed it with lambs wool.
Overall, much much better.... but way overdamped and dull.
The mid and tweet now have more of an "ambience effect" than
the woof... so you can distinguish the drivers (ie: no blend).

I know... just take some stuffing out.
But..

Upon further listening and exerimenting, taking enough out to
get the above right, the original prob comes back... so I'm not getting
the right mix of solving the 2 problems.

Also, and more importantly, I've discovered that most of the nasty
sound is from box reflections bouncing around and comming back
out thru the cone and the (rear-firing) port.

Soooo.... stuffing enough to kill that, also kills the "ambience" and
causes the overly dead sound in the lower-mids/lows.

I could sure use some help to get this solved, and preferably quick.

It should be said... the over stuffed condition is way easier to live with
and not that far off from OK.

Thanks much in advance!!

Hi Greg,

Try removing all but the eggcrate and sticking a sock in the port. Adjust the sock(s) so the amount of material density changes as you take turns listening. If that works, try and duplicate it with the lambs wool.

No I'm not kidding.

I'll second that emotion (with regards to the eggcrate). I've never had good results with that stuff, and it takes up a lot of volume. With such a high Qts, you probably need the space. I am really fond of carpet tiles, glued on with silicone sealant.
