Are film capacitors directional?

They are not polarized(as electrolytics are), but- YES; there is a preferred direction, with regards to orientation. Some helpful insights: (http://jimmyauw.com/2010/04/24/observing-inner-and-outer-foil-of-some-popular-capacitors/) (http://www.audience-av.com/capacitors/a_applications.html)

If you plan on getting serious about your electronics: Bite the bullet, and buy a Fluke(http://www.ebay.com/itm/Fluke-114-True-RMS-Multimeter-/250994535268?pt=LH_DefaultDomain_0&hash=item3a7070ab64). The 114 will resolve down to 0.1mV. I've had my Fluke 6020B forever(well, way over 25 years anyway), and never had the first problem with it. Of course; now Fluke is made in China also, BUT- automatically selects for AC/DC =;^) (http://support.fluke.com/find-sales/Download/Asset/2634055_6116_ENG_B_W.PDF). I just bought the same one for my son at Grainger, and BOY did I get screwed on the price. Double what they sell for(new) on eBay(he was in a hurry, and it was the weekend). This one is more versatile, also reading mA(nice, if you get into tubes), and capacitance: (http://www.dealextreme.com/p/fluke-17b-2-6-lcd-digital-multimeter-meter-2-aa-included-28659)

YES- in the photo; you have the Mundorf outer foil leads connected to the x-over's inputs, which is correct(for a series circuit). Reread point three, of the auriCAP advisory, regarding connection in a x-over circuit.

You owe me a Coke, Al. We must have hit, "enter" simultaneously!

Hehe....Next time? OK; you're on! Happy listening guys!
