Atlantic Technology 262 PBM crackle sound
 
I'm not sure what's going on with this and I'm not exactly sure how to describe it.
It doesn't seem blown since most of the time it sounds good (even at high volumes there is good clean bass)
Every once in a while I'll get a crackle sound when it's trying to play the bass. This can be at any volume.

Is this a bad speaker or something else?

If it is a bad speaker, would I be better off replacing just the speaker or getting something else?

Here are the specs of the sub

This is mostly for Movies.
The sub is from my family room speaker set but I moved it to the main Movie watching room.
The rest of the set is Polk (as shown in my sig)

Well maybe you can run some test tones on the sub and see what frequency it happens at.. it could be a blown driver or loose object in the sub?

Look into something called tinsel slap. There is a wire that attaches to the spider which is under the cone. Sometimes it can come unglued and slap the back of the woofer cone causing a rattling or cracking sound. If it is that it’s super easy to fix. You’re going to need to remove the woofer and inspect it to find out.

I checked the items mentioned but didn't find anything obvious.
This sub is pretty old so I've been looking at replacing it.

I'm considering the Polk HTS12 and the reviews seem mixed. What are some thoughts?

My room is about 11' x 11' and my speakers are listed in my signature.
