Greetings.
Due to the lack of good retail speakers that fit my needs i`ve decided ill be going the DIY route(and because im in no hurry to finish the project maybe by the end of the year i have plenty of time to research and tune before i even start ).
For drivers i`ve decided on:
HF:VIFA NE25VTS-04
MF:SB Accoustics SB12MNRX25-04
LF:2xFountek FW168
Decided on 3 way because i want to front port and that should prevent any midrange leakage to the port my question on this regard is are there any other parameters (driver specs , box tunning etc)that i have to take into acount when designing a speaker that would work well closer to a rear wall(i dont have much space maybe 1/3ft.)?

First the warning that a three way is much harder than a two way 
Now that is out of the way. the SB mid is a very nice little driver, but if you parallel up the Fountek's (and have them close to the wall) then they are probably going to end up being more sensitive than your needs, and the mids will probably be a bit subdued, unless you pad down the woofers, which isn't a great idea).
That being said however having extra spl available in the bass range may be an advantage and allow you to start rolling off early to get a target that boosts your low low end.
Basically being close to the wall means that the baffle step effect will be much less, meaning you have less of a drop in sensitivity in the bass frequencies than you would if out from the walls. a good run down on baffle step is available here Baffle Step Compensation
