external porting>?

[JJ.]

Ok so all box will be 1" thick as I already have sheets of it with a 2" baffle was going to do port in 2" so I can get a mega flare rather than just a round over.

Appreciate the help guys trying to go state style build as you seem to tune/build your boxes different to us in the UK.

So bracing is taken care of its a 1" diameter steel bar with a plate welded either end to bolt to front baffle and rear panel so that will be solid. I've allowed the .25cuft for that.

Not sure why your saying 3 shared walls as the port will bolt on top of the box?.

Sorry if it sounds like I'm being stupid guys never used Torres calc and never had an external port have ays done slot ported boxes/walls.

I'll aim to be around 31-32hz tuning wise but as said with a drop on port I can change very easily.

kool looking box

common walls is 3 because port touches both sides and the back. Which is an l port, such as yours.

EDIT: Since i had a double post i thought i would come up with something, might be able to tweak from here if it doesn't work out.

Thanks for that dude, going to go back and re read the torres thread as I don't think I am getting my head round it too good after using BBP6 for so long.

^that one looks perfect except for the fact that bracing isn't taken into account.

with bracing you're probably gonna end up tuned to 32 at a tad more than 12 cubes.

if you want to add a 45 or two bracing will be about .3 which gives you 6 cubes per sub.
