I just recently paid $12000 for a pair of JBL S4700 speakers down here in Australia. A dream come true, YET when I opened the boxes and unpacked the speakers I found as I tried to screw on the isolation spikes, all BUT ONE screwed on smoothly! One of them required me using pliers to screw it down as the internal thread was not cut exactly!!! I felt sick to my stomach, I was enormously cautious and screwed it down without damage or scratches. However all I could think was that this would not occur on a $12000 (with a RRP of $20K!) pair of top tier speakers from many other hi end makers. It really saddened what began as probably the most exciting day I had experienced in years. Has anyone else had any problems from JBL's Synthesis range?
