what size enclosure for these speakers

Both of your links are tweeters. Maybe one should be a woofer?

Both are the same link which makes it the same tweeter. ;)

What size enclosure will I need to get it down to 100Hz ? and should I port it and fill it?

Well, you didn't post the link to the woofer, so I can't answer that. But you can answer it yourself if you enter the TSP in a simulation program like BassCADe or WinISD (Pro) etc. That's the easy part, the crossover is much more complicated.
 
I already have them on hand and was going to make a set of micro monitors to use at work because space is limited. I was going to use only the woofer speaker but thought using the tweeter would make a nice 2 way micro monitor.

I definitely don't have the understanding to calculate the volume or porting if necesary

The boxes will be tiny, so I'd go ahead and try them in a ported config., and if you don't like them, it's no big deal.

Using WinISD, the box should be approx. .8-.85 liters in volume, with a .5" x .5" x 3.5" long port for a tuning of ~75Hz. Don't forget the driver displaces volume, so you'll have to guesstimate that. If you have some 1/2" ID tube to use for the vent, then it would only be 2.7" long

The Q on this driver makes it hard to get a decent alignment. I fiddled a bit, and i'd suggest 0.7 litre tuned to 95 Hz with a high aspect slot vent. F10 ~70Hz.

Larger gets pretty ugly, smaller has a big peak before rolling off. The 0.7 litre box also has a peak, but it is small enuff to get flattened by the slot vent.

The 1.1 litre box (0.4 ft^3) you suggest getting will need to lose some volume (vent, vent shelf, brace would eat some.

That would make the box appear bigger. Rocks would work (or bricks, tiles, blocks of wood).

½" MDF is not a very good material for speaker boxes so tiling the insides with something solid might help there as well.

Blocks of wood.... This is a good idea. I have some hardwood flooring scraps I could use or 2.25" piece of a 2x4 would work i think
