help with x-over on a mtm design

[BIGDAWG56]

hi trying to find the right point to cross these over at. the woofers will be wired in serious to create a 8 ohm load and the tweeter is 6 ohms, sorry i forgot the woofers are dayton rs180-4 and the tweeter is a seas 27TDFC. I was going to go with Zalph BAMTM but the my onkyo will not handle a impedance lower than 6ohms. I was trying to use x-over 3 pro but the graph just didnt look right, also i want to build these without a BSC because i plan on building the box and mounting them inwall then covering with drywall i just finished my infinity simple 12 build as my first project to cover the low end. 8O thanks for helping a noob

Here is my crossover design for my mtm inwall design someone please take a look and tell me if im on the right path.

Might want to take a look at the Modula MTM, NatP, and NatP in-wall in the Missions Accomplished section. These use the shielded RS180 but the basics of the crossover design are similar for the RS180-4 due to the cone breakup...So a second order design probably isn't the best choice for these metal cone drivers.
