are horn loaded boxes tuned the same way for daily driving as for SPL competitions?
are they specific to driver parameters? because dBDon's site has quite a few generic horn box plans but for no specific driver.
what is the best source of information to start the math on designing a horn loaded box? anyone thinking about whipping out a computer program for it?
finally- are these practical daily driver setups for those who don't want to spend alot of money on big amps and speakers (in turn, needing to upgrade power system)? will a 100W speaker/amp setup be comparable to a, say, 400W sealed driver setup?
what do you guys think about transmission loading? doesn't look as beneficial all around as the horn loader to me.

Horns have quite a flat responce. The lower cut off freq is mainly to do with the size of the mouth (ie big mouth required for daily driving, low notes) The upper cut off is to do with horn length/throat/chanber ratio. The peak SPL note will be somewhere inbetween these two.
They can be very efficient if done right, and if you will only be using a 10, then you can get quite an efficient horn, due to the horn to free airspace ratio (horns are most efficient into free air)
I have seen a couple of horn programs on the net, although best thing to do is get hold of old books on the subject.
Horns do like speakers with a high BL, but thats about it.
See my web page for some pics of my horn, its peak note is 61Hz, but its only 3db down at 40Hz. (from there on in, I have a subsonic filter)
