   Doesn't sound like an ILS localizer then.   
   What's the name of the nearest airport with airline activity in your area?

   They're probably only approach paths because ILS localizers are on the very   
   same heading as the airport runways using the system and must remain that   
   way so that planes can follow it in, along with the glide slope,  for a safe   
   landing no matter what the  visibility conditions.

   I've got some recognition books, and check around online, and besides, I'm   
   totally into flying machines ;)

   The P180's 'weird' sound is caused by the tips of its high speed props going   
   supersonic, which makes its audio signature really stand out. Even older   
   planes, specifically the Boeing Stearman, particularly those with more   
   powerful engines, like the 450hp engine, usually used in air shows, has the   
   same effect when power is applied and the revs shoot up, then you'll hear   
   the tips of its two bladed prop go supersonic and make the same kind of   
   sound, but the P180 Avanti has two five bladed props so the  effect is much   
   more audible.

   I've been 'clean' more or less, usually more ;)

   Maybe you can use them with the Steinberger when you get it ;)   
   But if they're subwoofers, that could be a problem ;)
