If your speaker is making those sounds, it's either blown, or you are clipping your amp, or you are bottoming out your woofer. The latter two options will likely blow the speaker if it's not already blown.
Clipping the amp means you're putting a lot of a specific type of distortion into the speaker. This always sounds bad, but if you do it for an extended amount of time, it will also permanently damage the speaker. A small amount of clipping for a short amount of time will sound bad but would probably not permanently damage anything.
Bottoming out the woofer would mean you're driving it so hard that the cone of the woofer is physically hitting the metal frame behind it. If you do this very slightly for a very short amount of time, you might not damage the speaker, but generally it's quite easy for it to become damaged in this scenario.
Honestly, it's still unclear (from the information you provided) if you have a speaker or receiver issue.
I suspect you may have both a receiver that doesn't put out enough power for you AND speakers that cannot move enough air for you.
I suspect upgrading your receiver will lead to blown speakers, which will make you replace those.
If your speakers were already blown, that could damage a receiver (including a new one), by the way. Especially if you try to crank the volume when the speaker is blown.
Edit: While I said bottoming out the woofer, it's possible to do so with a tweeter too, especially if your receiver is clipping. I just defaulted to saying woofer because in my experience it's usually the woofer that reaches its limit first.
