So, I was dumb. Drummer in my band plays at high volume, drives guitarist to crank his volume, leads me to turn up my GB Shuttle 9.0 without thinking about the load it is sending to my cabinet. The top speaker now has a nice crackle with every note played - this is VERY fortunately a slow time for gigs but I still have 3-5 rehearsals a week and need to fix this sucker ASAP... next gig is in ~ three weeks. I've done some Google and TB searching but have not found any helpful information on replacing this speaker and am fairly uneducated in the world of speaker components - any help would be HUGELY appreciated. I'm not sure which brand(s) to check out for Neo replacements for starters... from there I can probably find a few guides on replacement method. Thank you, TB, for helpful a bassist in need through hard times.
