Eph,Yes, 1/3 octave test tones are too wide to precisely identify the peaks and nulls in a room. They're still useful though, if only to show how bad the response really is! If you play ANY low frequency tone and walk around the room you'll immediately hear how the level varies all over the place.
I've use SoundForge to create sine waves at 1 Hz intervals up to 300 Hz, but lately I've been using Vincent Burell's freeware sine wave oscillator program. It can play any audio frequency through a computer's sound card, but you need to connect your computer to your audio system.
You can download it for free here:

Look for "LF Generator 1.0" on the lower right of the page.
