Hey guys,
Essentially what is happening is every maybe 2 months or so, I'll be watching a movie or playing a game and I will notice that my left channel sounds muffled, or lacks treble. I can then replicate it by spinning around in a game to test it's accuracy with a constant noise, usually showing that it is indeed muffled. Same with highlighting music in the left or right channel and comparing.
I decided to swap wires from the normal sounding right channel to the left, while listening to music with defined treble patterns, and sure enough the speaker still sounded muffled. If I take the grills off of the speaker and put my ear to it, I hear/see sound and movement from the three woofers, but a very faint representation of the treble from the tweeter it seems.
I know it's a long story, but here is where it gets weird. As I hook up everything back to normal, and sit down , starting the music again, the left channel has all of it's treble back. In disbelief I went up with my ear to both speakers, and they sound identical now. I was ready to order a new one, but this caused me to hesitate.
Any advice as to what this is would help, really dreading taking apart the speaker as I have never done it. Not sure if the repair process for Pioneer products is okay either, but the speaker was purchase earlier this year. Thanks!
