Sounds like they have been driven so hard the diaphragm stretched to the point where its contacting the stator(s). First test you should have done, always do, with something like this is swap channels to narrow it down. Least likely but easiest is swap channel inputs into the amp. Also unlikely and slightly less easy is swap speaker cable ends on the amp. If you have the extra few inches that will be needed for that. When the left speaker now driven by the left channel still pops then you know for sure I was right, er I mean its the left speaker that's bad.
Weird problem noticed today...
This has never happened before but in my Bluesound Node 2i today there is - I can it descrbe is as - bass slap or pop, I think just coming from the left Maggie. I pretty much only play loud. My subs are right behind the Maggie (16" or so) and it's definitely coming from the Maggie. Now the DAC on the Bluesound has a lot more boomy bass than the CD player DAC - Yamaha Aventage BD-A1060. So I am thinks my it's signal-related but perhaps it's the Maggies only they are not being driven hard in those frequencies enough to make that horrible sound. BluOs just did an update that is only major change to system today. I probably hadn't played music on a couple weeks and BluOs asked me to do update then I noticed problem - could be coincidental though could this be an amp or preamp issue?
Thoughts?
