Hi, I have a set of JBL TLX320 floorstanding speakers which have served me admirably for the past 7 years, but now the tweeter in one of my speakers is seemingly at its end, as it has lost some of its sharpness, it sounds a bit "flat" compared with the one in my other speaker. I originally bought the speakers from Richer Sounds, but they cannot supply me with a replacement tweeter as they ceased stocking JBL stuff a few years back. I tried going to JBL website and they only deal with US customers, for UK peeps they link to a Harman Kardon site which I have mailed an enquiry about but have had no reply. There must be some other stockist of JBL speaker spares in the UK (or preferably N.Ireland where I live), can anyone give me any recommendations? Many thanks in advance! Regards, BAM.
