I've been reading through some of this thread, hoping I might find some help with my Energy speaker's "buzz", but I haven't found anything...
Here's my situation:
- I bought these Energy 3.1e speakers at least 10 years ago and I've always been very pleased with the audio quality. I really don't want to replace them at this time.
- I've been using them in our home theater/audio setup and they probably have close to 10,000 hours of use so far (based on ~2 hours per day on average - the majority of this at fairly low audio levels though).
- Within about 3-4 years from new, one started to develop a very minor "buzz" at about 225 Hz, but it was so minor at the time I didn't want to send them in for repair (5 year warranty).
- Searching the web at the time, I found this was a fairly common problem with these speakers due to a flaw in one of the internal baffle attachments (at the time people mentioned sending them in for warranty repair).
- Over the past few months, the 225 Hz buzz has suddenly become extremely loud and it now resonates regularly when listening to music, watching movies, etc (it used to be only audible when sending test tones to the speakers).
- The buzz is not a problem with the drivers, but instead something resonating inside the speaker enclosure.
I was expecting to find through a Google search, information on how to carefully take apart these Energy speakers and repair whatever has come loose, but I haven't found anything at all on this.
Looking at the enclosure, it looks like the rear panel is bonded in place and I'm stumped as to how to get inside. I also can't find any screws, nails or anything holding any part of the speakers together; not even holding the drivers to the enclosure.
Do any of you have experience taking Energy speakers apart? How are they held together? How are the drivers held in place? Do you know of any web links with pictures?
