Hi! I've tried swapping speakers and while the problem changes in sonic character when I do so, it doesn't change in regularity of occurrence or in the method of remedy. Amplifiers have been changed repeatedly, it's a rainy and otherwise extremely humid climate, and there are no antennae of any kind hooked to the system, indoors or on the roof. Even the TV is used strictly for movies.
I'm interested to hear you talk about crossover parts being possibly related somehow, though, because I've been trying to convince a fellow asylum member that the problem consistently shows up more in the left (and particularly the left-front) speaker, despite change-outs of different kinds of equipment including speakers, and he doesn't believe it.
I've blown two left-side tweeters during all of this, as well as the front-left channel of two separate multichannel amplifiers when hooked to still other pairs of speakers. On one memorable occasion, one of the Monarchy SM-100's I was using was audibly bottoming the left-front speaker drivers in a really nasty way, and when I swapped the speakers themselves, physically moving the left one to the right side and the right one to the left side, the problem disappeared completely and everything worked fine.
The other A'goner says it can't be that some kind of pernicious interference is being radiated in to the left-front crossover from somewhere else because the fall-off in intensity would be so quick, over such short distances, that the source of the interference would have to be right up against the speaker -- but this being said, the problem very often sounds like speaker distortion. On my Songtowers, it sounds like all my female vocalists are "blowing out the mic," whereas on my Linn Ninkas it sounds like someone in the next room is running a hair dryer and the motor is putting a noise back into the AC. The Audio Physics Spark IIII's I had dealt with it by just, well... melting, essentially.
Further thoughts?
