Speaker Frequency Range
I am looking to use a test speaker for my power amp. I was wondering: if I use a speaker with a frequency range of say 100Hz-4000Hz, and I give the speaker an amplified signal that ranges from 20Hz-20,000Hz will it see any damage? Or do I NEED to incorporate a crossover just for testing purposes?

How much wattage are you talking about?
You'll be fine as long as you keep the power low."He who fights with monsters should look to it that he himself does not become a monster. And when you gaze long into an abyss the abyss also gazes into you." Friedrich Nietzsche -
Should be fine within the physical limits of the test speaker.
Where you need to be careful is driving, e.g., a tweeter with a wide-range test signal. Significant signal level at a frequency near the driver's Fs (resonance) can be deadly. Actually (and many will disagree, and be theoretically correct) one may carefully test a tweeter with a wide-band test signal, but only at very low level (input voltage) and very carefully. If I were testing an expensive or irreplaceable HF driver, I'd throw a cap in series with the test signal to ensure LF is kept away from the driver.
HTH (as they say).
