While I was enjoying a long heavy metal session (4-5hrs) on Friday afternoon (I know..."Can anyone listen to heavy metal that long ?" Well...you can if you're an ML/vinyl user ) I noticed a resonance developing in the LH panel towards the end of the session....
Having been plagued by "resonances" recently (including one almost unaccountable one) there was no confusion with this particular item and I immediately pointed an accusing finger at the spikes. As always, it's the last one that's the culprit and always one of the over-extended spikes at the back.
It just shows that when one or more spikes are borderline, a good thrash of high octane heavy metal will reveal their condition in no time.
It's been at least 18 months since I last registered a similar problem but the thought occurs that it may be a good idea to adopt a regime of tightening them as a precautionary measure - perhaps once a month - just to avoid the prospect of the speaker falling over halfway through "Child in Time" by Deep Purple .
Another thought occurs that the spikes are not that easy to adjust with exact precision.i.e you could easily end up with a 1 micron gap on one of them when finished.
I find that "tuning" each one by tapping them with a finger until they register identical sound is helpful.
Hope this helps some unfamiliar Users.....other helpful suggestions always welcome...:music:
Kind regards..........................Victor.
