If there are no pics/sound..., it didn't happen:
This is the spectrum for the Heil without the reflector in place.

Here we add the reflector with the 1MM spacer. Knowing that the woofer has a very steep slope at ~3,500 Hz, what would you rather listen too?

Now we change out the 1MM spacers to 0.6MM. The problem with working with media this thin, you don't get a smooth edge. But, note how the frequency balance has shifted down just a hair. The real gains occur when you get <0.2MM, but this looks pretty darn good to me.

So, what kind of $$$ are we talking for such a shift, which is probably more than you would get from swapping cables? Maybe a couple cents.
