Just a thought: if you're stranded in a ravine with a broken leg, luck will often determine who runs across you (assuming someone does, in time), and you won't know if they have hearing impairments. But I'm hoping that SAR would have decent hearing.

If YOU don't have good hearing, it doesn't matter too much if you're the one they're searching for. What YOU would need is something that THEY could hear.

So, I guess you might need both a woofer and a tweeter...
