    Is there an easy way to tell if a speaker is blown or am I just pushing it too hard?

    Ah, if it sounds good until you push it real hard, then you are pushing it too hard. If it always sounds bad even playing soft it might be damaged. If it makes no sound but your amp works with other speaker cabs, it's blown.

    a sine sweep may detect a damaged voice coil.

    Another test is to GENTLY push on the cone by spreading out your fingers and pushing GENTLY. If you feel any scraping the you've got a problem. It can be fixed by having a recone done.

    If you have IOS there are several low cost "Signal Generators", and real time analysis. In fact full speaker measurement suites for more money.

    You can checks for cabinet resonance, rattles, loose braces, etc that speaker drivers often get blaimed for.

    Seismometer apps also, just lay the phone on the cab and check for excess rumble, or put the phone on the stage floor to see if coupling is a real thing or not.

  10. For Android phones I use "PA TONE" It works well and has various tones that you can easily adjust in pitch and volume.

    Edit: just saw B-string's link.

  11. Remember that the cabinet can masquerade as a blown speaker. If you have a joint that has come unglued and is rattling or letting air through it can sound pretty horrible.

    It can sometimes be diagnosed by pushing on the various sides of the cabinet while you play, but that is by no means foolproof.

    The only other comment I will make is that the distortion control on a fender super twin sounds just like a blown speaker.
