RS152 surrounds popping - with mutiple receivers tested
Sorry for the long post, but please bear with me...
I've got something that's been driving me crazy. My RS152 surrounds usually pop when I turn my stereo on.
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. 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 things work perfectly.
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. 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.
Do these speakers have a capacitor or something in them? How do passive speakers store power the discharge it without being plugged into anything? One speaker in particular usually pops louder than the other, regardless of which receiver terminal it is plugged into. 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.
As near as I can tell, this only happens after being turned off for a while, usually overnight. The longer things are off, the louder, more energetic the pop.
Other than this pop, they sound great and I'm in love with my setup. BUT this pop is driving me crazy and because it's often loud and energetic, I'm concerned about long term implications with regards to damaging the speakers. The fact that they BOTH pop (albeit one usually louder than the other) has me concerned this might just be a design flaw and not indicative that I got a lemon.
I'm completely confused by the whole thing. Anybody else experience this? Ideas?
