VERY STRANGE - VC is well-centered in the magnet gap. Moves easily in & out with very light finger pressure. No scraping, no noise!
I looked for bad glue seams on the cone>surround, spider>cone, loose/cold solder on tinsel leads from terminals. All seem to be OK!
Sound is extremely "grainy" indicating IM & THD - I'm gonna put the o-scope & sweep generator on it tomorrow to examine further...
VC DCR is normal, = to mate, = 3.5 ohms. Never seen this exact problem in 50+ years! WHAT AM I MISSING? HELP!
ALSO: How is the KG4.2 an "8-ohm" speaker with a 3.5 DCR Woofer? Marketing again? Still love my stacked KG4's!
Thanks for any ideas you may have....
I am - (as they say) - BAFFLED!
