I am using a pair of JBL Studio Seris S-310's in my HT setup and noticed something odd a few weeks ago. I took off the grilles to the speakers while I was rocking out to Kid Rock to see how much the woofers were moving. That's when I noticed an inconsistancy.
The woofers were fine, but the midranges on the speakers were performing differently. One midrange was barely moving and the other was moving a good deal more. I could hear sound coming from both, and neither sounded like they were crackling or anything. I figured the midrange that wasn't moving was the defective one so I sent it to the repair shop.
I recieved a call a few days later from the repairman at the shop and he said he couldn't find anything wrong with the midrange. He said the midrange isn't supposed to move, but he would replace it anyway since it was under warranty.
When I finally got the speaker back I tried rocking out to Kid Rock again to see if I could notice a difference. The funny thing was that the midrange on the repaired speaker still didn't move.
What is going on here? Is the midrange supposed to move or isn't it? The repaired one moves so slightly you can barely tell it's moving while the other speaker's midrange is moving so much that it resembles the movement of a woofer. Is my other speaker really the one with the busted midrange? How can I tell? Maybe some other owners of the JBL Studio Seris S38, S310, S312, or S412 can see how their midranges move when played at high levels. Any help would be greatly appreciated.
