regarding the tweeter baffle, I had the same problem when i built a pair of SMT212's.

Everything was cut & fitted perfectly as per the plan, until i got to the last panel which was the tweeter baffle.
 
Just like you i had to fit it above the deviding baffle & trim a small ammount of the top of the baffle to alow it to fit.
 
As soon as i descovered this i checked my baffle against the plans, to me everything was ok, dont know why it didnt fit.

oh ye sorry i forgot to add that in my build, its the dividing section between the 12's and the compression driver, its 15mm to long in the depth,
we should ask staipe to edit the plan realy before more peeps make the mistake..

looking good so far btw

p.s. what "Q" did you use on the 150hz EQ cut? and how many DB?
i still haven't got round to running an RTA through mine...

Got the tops and bottoms cut.  Get to put it all together tomorrow :)

I put a -6dB drop at 170hrtz. 

Also, I was using the wrong horn for my compression driver.   Ordered new horns, so we'll see how they sound.

Er, canceled that order.  Horns were fine.  Crossover is just, crappy.

Can't really complain, since they came with speak-on plugs, dish, and xover.  Just going to replace the tweeter network, as I want the dish and speak-on plugs.

Here it is!

All that's left to do is get them painted.  Trying to decide between black, and turbosound blue.







This one came alive.

I thought the baffle for the 12's on the SMT was meant to have  a couple of triangular 'ports' cut into it?

It seems to sound better without ports with the drivers I'm using, so I did not make any ports.

i would have cut a bigger rectangle and stuck an animal horn in there.  That horn looks pussyish. Make use of the space in that cabinet.

I would use a 2" CD, but they're just way to expensive.

you can get a 1 - 1.5" big horn and stick a small compression driver to it, like an RCF N 450, not alot of money

I took these things outside today.  Had them atop four scoops.  There's a freq. gap there, but overall everything sounded fine. 

I feel really sorry for anyone who walks in front of these things.  They are pretty damn loud.
