Open baffle design help.

Starting a new build, 3 way with an open baffle for the mid and tweeter. I started the woofer section today using a Dayton DVC 8 inch subwoofer for the low end. Dayton rs125 mid and the rt003c tweeter.
  I plan on using dsp for the crossover with a cap on the tweeter for protection.
   I'm borrowing very heavily from Paul's Sunflower and Siegfried 's many open baffle builds. 
  The baffle will be 11 1/2 inches wide and have a 3 inch "wing" going straight back. I hope to get the mid-woofer down to 300hz, and cross to the tweeter at 3k. 
  This is my first open back build and would love a sanity check.
  Thanks!

...and borrowing from my Stances as well?

   The parts were too good to leave on the shelf any longer.

The crossover point, slopes from Ben's Stance would be a good place to start. That speaker sounds great.

my 2 cents; set your mid HP and measure (my sugestion for this 5 in would be try HP filter at 280Hz, keeping knee under 300Hz... I use 240Hz with a 6.5 in celestion coax)
use your woofer with dsp to fit LP into the measured roll-off of the mid (slope and knee frequency)
