  7. Ar7 tweeter replacement

    hi so everything is right in its place.As I thsought the wire were short so i had to ad some wire.There was enough clereance for the tweeter magnet but of course I had to trim some wood for the connections.Took me one hour to do all.The new tweeter is a little higher frequency but since the ar has the switch behind i had to put the new one in the standard gain position and the old one in higher position.The difference was really thin,and i think a part of this is the fact that i know the tweeters are different,pretty sure in a blind listening won't hear differences.Thanks to all,unfortunately i had to throw away the cabinet since the woofer was non original and i only got one speakers.Thanks really to all

    It is really of no benefit to remove the oval-shaped terminal plug - - it is loaded with staples and is made from 1/4" Masonite. If my memory serves me correctly, I snipped the original green and yellow tweeter wires right behind these terminals, stripped off the colored insulation, and then soldered or crimped new push-on female terminals to fit the male tabs on the tweeters as shown.  And yes - - - in order to snip these wires, the woofer must be removed.

    Let us know how this works out if you end up going this route. I have a couple pairs of AR-7's, but they both have very good original front-wired tweeters. If they were to ever fail or become damaged, I would have no hesitation about pursuing this solution to use substitute 038 tweeters with rear wiring.    

     

    Thanks I will disconnect the wire from behind and put females plugs.Let's hope the wire is long enough I would prefer not to make to much connection

    thanks again.Yeah I would love to have a pair but for now I only found one.I've already though about it iIwill fix one speaker than in the future I will buy the match tweeter or maybe who knows i will find two original front wired tweeters thanks.Since we are here.How did you do the front to back wire?Did you pull the woofer out and rewired everything or you removed the front wood wedge where the connectors of the old wiring are?

    Hi thanks the problem with the ar7(not the same pair of my last discussion)unfortunately needs to be rewired.Anyway if you tell me that the sound won't be compromise I will buy it as soon as the seller provide me with proof that works.About the fitting my brother is quite handy so I don't think is going to be a problem.Of course I will fit  it with back wiring.Do you know what is the difference in size?
