Hi Can anyone help out with any info on where to get hold of a replacement woofer for JBL Control One series. There's a very annoying rattle/buzz/popping when the bass gets a little meaty. There's no response from Harmon in the UK. Spec is... Frequency Range: 70 Hz - 20 kHz (-10dB). Power Capacity: 150 Watts (test signal of IEC filtered random noise with a peak-to-average ratio of 6dB, 2 hrs duration). Sensitivity: 87dB 1W, 1m. Nominal Impedance: 4 Ohms. Crossover Frequency: 6 kHz. Components: 135mm (5 1/4 in) low frequency loudspeaker 19mm (3/4 in) polycarbonate dome tweeter. Any help on where to get something like this would be more than appreciated. Many Thanks in advance.
