is there an audio file or something out there that lets you hear separate outputs from the speaker to see if anything is damaged???

There are files out on the web with tones at different frequencies that you can download. Test tones can be chosen to be within the range of particular speaker drivers based on crossover frequencies.

For example if you have a 2 way speaker with a crossover at 3 KHz a 5 KHz tone will be almost entirely reproduced by the tweeter. If you pick too high of a frequency, any harmonics or distortion may be at such high frequencies that your ear is not sensitive to them. For sure you don't want to go much higher than 5 KHz.

On balance, its the woofer that is more likely to be damaged, and test frequencies around 200 Hz can be very helpful.

If you pick low frequencies below 100 Hz, many speakers will start distorting due to a lack of Xmax, and audible faules here are not due to driver damage.
