Yeah, I was thinking I should add another brace behind the baffle, since that seems to be a bit weak, the rest of the cabinet is very solid though, and there is plenty of stuffing in the bottom of the cabinet to reduce standing waves.

How do you choose your 57 liters box volume and what will be the port measurement? I am making 3 ways towers with the 830884 and I'm not sure about the internal volume?

Choosing the box size should be the least of your problems. Download Unibox, enter the T/S parameters, and play around with the numbers, look at the graphs, and decide what you'll be happy with. Choosing the right port tuning and cabinet volume for you is a compromise between bass extension, power handling, and excursion limitations. For my design I chose a fairly large cabinet with a low tuning, as I don't intend to play my speakers at ear blistering levels, and would rather have the low frequency extension over being able to play real loud (read: I didn't want a subwoofer to hear the deep bass notes).

Thank-you! Different is exactly what I was going for.

Tips if anyone wanted to paint something with crackle paint:
I just want to add that this crackle paint stuff is fairly difficult. When painting the top coat, you basically get one shot, after you've done a few strokes of your brush, you can't go back over your first stroke if it doesn't look right, as the paint will lift up and bubble, and not really crack much. It just leaves it looking like terrible paint. It makes it quite difficult, because the cracks will tend to follow your brush strokes, so the paint has to be very even right off the bat for nice even cracks. I have read on the internet, that if you don't like it (it starts cracking within second of painting) you can wipe it off right away with a damp cloth and try again, but I didn't try this myself.

I painted the base twice, as I didn't like it the first time, but I just sanded off the first paint attempt. The base was difficult for the above reasons, and for the fact that it's all corners and curves.
