I thought I read a thread here in audiogon some months back where someone gave a site with a list of drivers used by various companies . I didn't persue it at that time , if whoever has this information could respond , We would appreciate it . If the list can't be found let's start one . All of us have replaced a driver sometime . We need to note which system , which brand and model driver was used . What do you think ? Wouldn't we be more effective in knowing which drivers sound best to our ears and which drivers irritate our ears or are too bright , ring ,or sound warm ? It would be nice to know how much a megabuck speaker manufacturer spends on their drivers .
