Some 1/3 octaveband tones for speaker respons testing.
This is just a few of the testtones available on Alan Parson's test CD, the free version of the ripper I've got only lets me convert some of the tracks on the CD. These should do for getting a general measurement of a speaker though. One thing that might interest some is to play the 1600 Hz tone at a level that gives 2.8 volts at the speaker, or 1watt/8ohms, and hear how loud that plays.
