Guest Posted February 2, 2002 Report Share Posted February 2, 2002 HelloDoes anyone have one tweeter for an AR 4x or one for an AR2AX? Thanks Brian O'Neillmbkpao@yahoo.com Link to comment Share on other sites More sharing options...
Guest Posted February 10, 2002 Report Share Posted February 10, 2002 New factory replacements are available for the 2ax tweeters, and we might have an original take-out from a 3a [same part as most later 2ax's].The 4x tweeter is a dinosaur, no original replacements are available. If you want to keep them stock you'll have to dig up a used original. Converting to a dome type tweeter will greatly improve their sound quality.4x tweeters were crossed over waaaayyyy too low, around 1.2 kHz, and only at 6dB. The stock crossover is a single 20uf cap, changing this to a 10uf will improve their reliability and sound quality by raising the XO point to a more reasonable 2 kHz. It would also do to check the woofer coils in both 4x cabinets to make sure they are the same. I have seen several “pairs” of these with mismatched woofer coils. A 0.3mH coil would mate the stock 8” woofer with the tweeter quite well, stock coils I’ve seen ranged from 0.5mH up to 1.4mH. Link to comment Share on other sites More sharing options...

Guest orionkc Posted May 27, 2007 Report Share Posted May 27, 2007 I just found this thread while reading through many others. I have a set of AR4x's. I was thinking about recapping and have a set of Kimber Kap 6.0uf's. I bought 2 sets while doing my AR3's. What will happen if I install the Kimber 6.0uf instead of the 20 or for that matter a 10? The original are big blue sprague 20uf capacitors. Do they loose their capacitance over time?Thanks,Rick Link to comment Share on other sites More sharing options...
