Hello everyone, Although I'm new here I've been an Altec/JBL freak since 1975.
I've a set of 4312A speakers. have had them for about 7 yrs. For their size & what I paid for them they sound great to me. Purchased them in near mint condition. They are still near mint...or so I thought.
On both speakers the woofer appeared canted inward slightly, about 1/8". I held a metal straight-edge ..horizontally across the center of the woofer. With the straight edge carefully placed against the outer frame gasket........sure enough!! No doubt about it, the woofer is "canted inward" on the left of the frame. There is a gap about 1/8" between the cone edge on the left......on the right, the woofer touches the straight edge. Both speakers have this strange oddity.
I only dicovered this about a month ago. The speakers sound great, no problems that I can hear and I've gotta wonder how this can be! Others have told me not ta worry about since the speakers work just fine. I'm just confounded. Perplexed!!
How can a woofer still be working fine....if one edge of the cone is canted inward.....1./8" no-less. Does anyone know if this was a common defect in JBL "white woofers"?
BTW....I never did buy the "woofer sag" myth.....besides, my woofer offset issue is horizontal.
Anyway, just curious that someone out there might know of such speaker oddities. Lansing Heritage is Awesome!!! whoever created this site.......bless you & thanks, RUSS
