Looking for feedback as I've just experienced a more serious effect of a usual occurrence when firing up speakers with metal drivers.
The outside temps here in Detroit had been, for the better part of January/February/1st half of March, Arctic in reality. A high temp of 10F was common and many times less than that. I have a pair of Monitor Audio S-1 small bookshelf speakers and they'd been residing in a hallway closet that doesn't get any heat, since last November. I brought them out today and hooked them up to my Croft Polestar 1 amp via PS Audio speaker wire and started spinning LP's. Holy cow...muffled much? I know from past experience that these speakers with their metal composite drivers, can take a few minutes to get going when sitting for a couple of days without use, but this session today was getting on to a couple hours of 6 sides of LP's...Canned Heat, Spirit, Johnny Winter/Rick Derringer, and then finally...voila!...Ziggy Stardust broke the death spiral and came blasting out in all it's rockin' self. Whew! I was just about to swap wires, adjust the dip switches on the back of the Sonneteer Sedley phono stage (add some capacitance), swap speaker leads/jacks, etc., when the MA S-1's started loosening up and gettin' it on.
I'm wondering if anyone else has come across metal drivers needing some time to come out of hibernation, either in a short warm-up or one as extended as I just had. In any event, glad they came back to life! j
