My entire HT setup consists of Infinity's most recent Reference line. I've tested things with a Sony ZA1100ES and two different ZA810ES receivers (one out-of-the-box new) with the same results, always when the power relay engages. So if the receiver comes into play, it must be a Sony ES thing, although I've tested things with Atlantic Technology and Polk Audio speakers and they work perfectly with these receivers.
I've tried lowering the volume before turning things off, muting, switching to every different setting I can think of, turning off all surround settings (leaving on the front stereo speakers only), plugged the receiver into different outlets, swapped out HDMI cables, unplugged the sub, w/ and w/o banana clips, swapped out speaker wire (14AWG for 12AWG), etc., and I'm out of options. Even if I plug the surrounds into the front speaker terminals, they still pop. No matter what I've tried, after the receiver has been off for several hours (usually overnight ), when I turn it on, the RS152s will pop - often quite loudly.
What's most perplexing to me is, if I unplug the speaker terminals from the back of the receiver after it's been off for several hours (but before turning the receiver on), and touch the leads together, the speaker will pop. None of my other Infinity speakers do this. It does not matter whether the RS152s were plugged into the front speaker terminals or the rear surround terminals, they often pop if I unplug and touch the leads together after hours of non-use.
How do passive speakers store power the discharge it without being plugged into anything? The fact that the speaker pops when I touch the leads together tells me the problem is indeed with the speaker and not the (multiple) receivers I've tried, but I'm wondering if the Sonys are contributing to the problem. Is there some sort of power discharge that receivers are supposed to do that is not occuring with the Sonys?
As near as I can tell, this only happens after receivers have been turned off for a few hours, usually overnight. The longer things are off, the louder, more energetic the pop. BUT because the pop comes from both speakers makes me think it's more than just getting a lemon (because it would mean I got two lemon speakers with the exact same problem).
Is it possible that SonyES and Infinity surrounds is just a bad marriage? Three receivers and two speakers, all with the same results. Not sure what else to think.
I'm completely confused by the whole thing. Anybody else experience popping with their surrounds? Ideas?
Don't apologize for long posts. I'm the KING of long posts. I believe the more details the better. I usually hang around this thread because I have been able to answer most people's questions. I owned a STR-ZA3000ES and I now own two STR-ZA5000ES receivers. I recently got a Yamaha RX-A3060 as well. I own a pair of Klipsch RF-7 speakers which are very big $3000/pr
speakers. I run my speakers with an external amp because even the 5000ES cannot provide enough power to them. My receiver pops every time I turn it on, but only because the external amp is already on. And yes, it does this with the Yamaha receiver as well. In the case of my "pop", it is because it's a analog amp converting to a digital receiver. If I turned on the receiver first and the external amp second, then I get no pop. But, that would require me to get off my lazy butt and turn on and off the external amp, so I deal with the pop.
I don't have a solution to your problem so I am going to recommend someone who can tell you what is going on. Call up a place called Speaker Workshop. The owner will answer the phone or if you ask a question, then the owner will get on the phone. He usually answers it unless his 80 year old parents answer it. He is a difficult guy on the phone because time is money. He also runs a very big outfit and he trusts NOBODY to touch anything so he does all the work himself and he is world renowned for his work. You can tell him you have a Sony ES receiver and I don't know what he is going to say about that. Him and I don't agree on everything. He loves the older stuff and isn't a fan of any new receivers. And Sony ES had some good years and also had some bad years. I don't think he is aware that I own two Sony ES 5000's. Focus on your speakers and tell him what exact model Infinity's you have and then tell him what problem you are experiencing and then quickly let him know that it has done this on several different receivers.
I honestly don't see how you are happy running your speakers on an internal receiver amp. And I know you are using a lower grade ES receiver because only the 3000 series and 5000 series support external amps. My speakers sound flat even on my Sony 5000ES with 140WPC or my Yamaha with 150WPC. My external amp which can be found used on Ebay for under $500 really makes my speakers come alive. Maybe your speakers are smaller than I am thinking? I am imagining big speakers.....
Call Speaker Workshop and talk to Tom. 260-426-8742. Also, lookup SPEAKER WORKSHOP on Facebook and LIKE his page. You'll see a big building with a Pepsi machine outside. You can read all about the business. He literally lives there and has devoted his life to doing this. He will be able to tell you why your particular pair of speakers are doing what they are doing. He rebuilds speakers all day long. Tell him Ted Hontz said hi. He has been wanting to get his hands on a pair of my original Klipsch Heresy with risers. This will definitely answer your question without you having to open up any more receivers. If you like the new series ES receivers, I'd recommend settling with a 3100ES or a 5000ES. You can get one on Ebay for a surprisingly affordable price. Then I recommend an external amp. PM me if you want to go this route so I can recommend what external amp to get.
