That sounds pretty cool.  I'd love to see it when finished.  I have personally always been a fan of small 2.1 builds.

I think I would try the smaller cap to begin with.  I haven't used that tweeter, but I am willing to be you are going to get some audible distortion if you cross too low.  It is impossible to say without really measuring it, but with a low order crossover, I think it might be wiser to try the higher crossover point first.  Just a thought.

Here's another quickie.

The Dayton Audio PC105-8, 4" full range driver is on sale through today. I figured, why not do a quickie? 

Put two of them in a 1 CF box (1/2" ply) with a 1/2" x 3-1/2" slot in the face, and it'll be tuned to ~53 Hz with an F3 of 41 Hz. Throw a tweeter between them for an MTM with an appropriate cross-over to get nice, almost full range.

 

Remember, this is about getting your creative juices flowing to see what you can dream up.  

 

BTW, I just saw the PC105-4 and did a quikie with them. Same configuration leads to a smaller optimal box with both BF and F3 noticeably higher, but switching to the 1 CF box is all but identical with the -8.

Great call!  I just picked up some PC83-4 and a few ND series tweeters.  I plan to do a small simple build for some people to do.  Free plans, of course.
