First Post! I picked up a pair of RTA-11TL speakers (minty...or so I thought) in May.
I had noticed in casual listening, that I would get an occasional "crackle" from one side. Being a positive sort, I figured it was due to questionable power, or numerous other low end amp issues (I have a fairly low rent sony reciever I use to push these while I build a 2 channel system to truly push them properly.)
Today, since I was inspired:
1. Made a sweep tone CD.
2. Determined the problem exists just in one speaker (after switching cabs to make sure the problem did not exist in the amp...and the second speaker performs fine on the same amp channel with the same source material.)
3. Problem APPEARS to be isolated to the mid passive radiator (with the small cap)
4. Noticed the passive radiator was slightly "crunchy" pushing it in.
5. Pulled speaker. Ran sine tone again. No additional weirdness. (though wacky sounding without the speaker in the cab.)
Thoughts to trouble shoot further? Source for new passive radiator? Go Fish?
