Dayton Audio H6512 6-1/2" x 12" Waveguide 1-3/8"- 18 TPI
What will happen if I use any horn like this that has a 1000hz minimum usable frequency with a horn that is cut much lower at 600hz? Will those bottom 400Hz not make it out?
That is correct, the horn will not support a wavelength shorter than 1,000 Hz.

You say, "industry-standard 1-3/8" x 18" while you cal this thing 1". You don't find that confusing?
This horn has a throat (or exit) diameter of 1". That's measuring the diameter of the hole the sound comes through at the back of the horn. The industry standard thread diameter for driver mounting is 1-3/8" by 18 TPI (threads per inch). This will naturally have to be larger in diameter than the throat opening or it wouldn't thread into the horn. Both dimensions are industry standards for 1" threaded horn lenses and drivers.

How would you ad this waveguide+ 1" driver to a 8" horn loaded speaker or a 10" onken cab
I am thinking that instead of the overpriced Fostex bullet tweeters, I can get a pair of these and a pair of high end 1" compression drivers. What would be the ideal set up to attenuate and control the outputs?My fostex is a Sigma 208 driver that begins to taper off at 14K.My onken 10" woofers are older Vifa drivers whose cut off I do not know.
The application of an L-pad would be the standard solution for attenuating high frequency drivers. The correct L-pad for your specific situation will be determined by the impedance of the driver you're attenuating, and the power you're sending to said driver. Here is a link to our selection of L-pads for your convenience:http://www.parts-express.com/wizards/searchResults.cfm?srchExt=CAT&srchCat=196
