Did I damage my new speakers?

Hey guys,

I am new to the speakers world - I have just bought my first decent speakers (Dali Zensor 1). But I need to know if I have ****ed up during the connection to the amplifier (Topping MX3). I forgot I left this amp/dac combo plugged into the electric socket (just wanted to check if it works at all, and then forgot to unplug it), and connected the cables. At one point there was a loud bang from one of the speakers, kind of a "pop" sound. But loud as hell. At that moment I noticed that I messed up, so I connected a source and tried to feed it some music to see what happens. Both speakers seem to sound okay from what I can say, but could it leave some permanent damage?
Yeah I know, I am dumb, lesson learned.

Thank you!

most likely a "bullet dodged".. a good wake up call... .. turn it up a bit and see how it sounds , if it sounds clean at your highest preferred volume for an extended listen , all should work out well...

Will do, just can't right now during the night. That would be a not so nice response from the neighbors

If there are any drivers blown, it'll be apparent even at moderate volume. If it's not distorting and woofer isn't flapping, you're likely ok.

When things like that happen, tweeters usually go first. If he puts his ear up to the tweeter (with something playing), and he either hears nothing or distortion, he really did mess up. If it is OK, he did, indeed, dodge a bullet.

The woofer is not flapping, seems like there is no distortion, only a constant low noise/murmur/rustle/DontKnowHowtoTranslateTheVerb (a bit louder than I would care for) when I turn on the amplifier.
I am thinking about taking them to a local audio shop to have them hooked up and looked at. They sound fine to me, but what do I know. I have exclusively used Senn HD 650 up until now.

that's just "floor noise" you are hearing i think.. it's amp related ... definition of floor noise in layman's terms.. low barely audible "white noise " sound at low volume ...

Try these test tones one speaker at a time to see if anything sounds "off" with one of them.

Usually damage immediately reveals itself so you are probably OK, but the test tones and sweeps should help put your mind at ease.

Put the volume low at first and then run them at a loud but not too loud level.

If it's a humming sound, it could be a ground loop issue. If that's the case, the issue can be resolved for less than $5 with a cheater plug.
