I recently bought some RefIV speakers, including the RF83's, RC64, and RS62's. I've had them hooked up for about a week now, and I love them.
Side note:
Please no questions about how they compare with the 7's, etc. I am novice at best with speakers and wouldn't be able to compare them. I had the money to blow so I splurged. This is the first set of speakers I have ever owned besides bookshelf systems. They do sound UNBELIEVABLE to my ears, though, and that's what matters to me.
Let's continue:
The past 2 days I have noticed that some television programming causes cracking in the tweeters of BOTH RF83's. Sometimes it is more of a "pop, pop, pop" sound, and other times it is pure distortion (ie during shreiky screams). It is fairly noticable. The programs that caused it were American Idol (Tuesday's broadcast) and True Lies on one of the HBO channels. I have digital cable through Cox Communications. I hadn't noticed the cracking before yesterday, but admittedly, I haven't watched much cable since I've hooked them up. I have mostly watched DVD's and listened to music. I haven't noticed it during DVD playback or music playback, and I have spent a lot of time listening to both. These speakers have not been abused at all. I have them hooked up to a Denon 3806 AVR. When I first hooked the speakers up, I cranked it a little[6], but certainly didn't push them to the limit. As a matter of fact, my AVR will go to a volume of +18 dBs (with no preset equalizer settings), and I never pushed it past +1 or +2. And that was for a very short amount of time just to see what I had bought. Just to see if it could be reproduced with other cable programming, I watched the Opera channel for about 15 minutes (all I could handle before I began projectile vomiting) and didn't hear one crack or distorted note. My question is: Do some cable programs have low quality sound that is transferring to my speakers to make them crack? Have my speakers blown? Any comments suggestions? Thanks in advance.
