ANYWAY: The box sounds ok with the Kicker C12 4ohm driver
installed now, it does sound more bass'ey to me,

Is there any wadding of any kind in the box? - no? - thought
so. Try this: take the embroidered pillow on the couch, the one
you got as a gift and hate, and toss it into the box and listen
again. If you want to purchase dedicated acoustic damping
material, then feel free to so do. Even if it does contain
damping material on the walls of the box, do this or something
similar that addes damping material to the box center.

Doing that will reduce the acoustic Q and make the bass tighter
and more precise. Just toossing loosely fluffed acoustilux or
similar acoustic wadding into the box will have a similar effect.
The embroided pillow on the couch that you got as a gift and hate
may not be uniquely the best material for this, but it is a fast
and easy way to test if that damping approach is likely to
improve the sound.

The box does have factory "wadding" inside.

Read the above again, try it or not as you please, but do understand
that wadding along the walls addresses midrange issues. It is also the
only damping that should be deployed for bass reflex bins, generally
line of sight should exist between either side of the unit and the
corresponding end of the bass reflex port(s). You can only, generally at
least - there are non-ideal bass reflex designs that rely on an acoustic
resistor, ie. damping, between loudspeaker and port to reduce the
coupling, deploy damping to the cabinent center in a closed box and you
should only do it if you need to reduce the system overall Q to
linearise the bass response. From your description just that appears to
be relevant.

The amp's cooling fins (heatsink) get warm, never "hot".

Oversimplified there is not likely to be an issue then.

I've been on the hunt this weekend for an 8 ohm 12" sub woofer,
which is hard if not impossible to find.

Monacor, Seas, Dynaudio, JBL, Scanspeak, Peerless ... just to mention
the first 6 product lines that are likely to contain something useful.

I may have to order it directly from A.T. if
they'll sell it to me?

I can't comment on this other than saying: Yees, getting the original
item is what will get your the original ssound.

The box sounds ok with the C12 installed, its just quite "bassey"

Welcome to the wonderful not so simple world of the simple closed box.
Just how large is the box?- do you have a spec sheete that perhaps came
with that C12?


Kind regards
