Looks like a good start.  You will definitely want some sort of baffle step compensation.  Typically it will be between 3-6 dB.. With them being on speakers you will probably be closer to 5-6 Db.  You would be closer to 3 if you put it on a desk. It doesn’t look like any of those would properly deal with the baffle step compensation. Based off your drawings, your down 3dB point should be around 400hz and 5 to 6db down between 800hz to 1000hz.  Try to something like an inductor value of around 2-2.2 to lower the steepness a little.  Then mess with the inductor to get the top end to be more even around 75dB. This is due to your one seat desk area.

I wouldn’t worry about the high end past 10Khz.  That probably won’t be an issue.  If you want to bring it down you could try a capacitor at the end.  

The reason with this woofer, you may want a tilted up axis is due to it’s off-axis response.  It will start beaming sooner, so you it will fall off axis sooner and faster.  Meaning if you listen more off-axis you will tilt it up higher. Granted, on axis will seem brighter.
