Have FX3022, bought in 2010, used till2012, been in storage since then. Took it out recently for function check. Found the HF/FR driver on the right speaker not working. Referring to manuals, found the specs for it. Took it to local technician who refused to repair it citing deterioration of SQ even after replacing the driver. He suggested me to look for actual replacement driver for it. So m here. Found local/Chinese drivers on Amazon but not sure about their compatibility and performance. Any leads in search of replacement would be appreciated.
