F200a has a true fullrange responce tweeters are not needed ,My cab in link gets a usable 30hz-21khz and can play loud on 2a3 amp.The JBL are very good but F200A is far more advanced.JBL has made some good products.But times are a changing and even f200a is getting a bit old.Was hoping for a new improved version but then fostex pulled f200a from the market after much demand they rereleased them.So probley no planed replacement
