  1. AR4x Crossover Rebuild Check

    in Acoustic Research

    Posted

    ....when I first got these speakers, I bypassed the treble pot.  One tweeter didn’t work at all, the other was in and out.  Worked ok then.  Used the speakers in my bedroom for a while....then on to the parts / equipment room.  A couple years later (having forgotten all I researched two years ago) I decide to rebuild / upgrade them.

    I thought that the waxy  “wallet” with the wires sticking out meant that there were two capacitors used in the design.

    The diagram(s) I was following used two caps....one of them has 265 written on the inductor coil..

    One of my speakers, I believe, has 265 written on the inductor coil (of course, the one in the picture I uploaded has a 5).....which is another reason why I thought I was in the right ballpark in my research.  The two woofers in mine look very different.  

    Serial numbers are  fx343364 and fx331864.

    i am again having trouble uploading photos....unsure why.

    i will try to use the diagram posted by jkent with only the 20uf cap and see how it goes.

    The way I wired it this time brought out the highs.  To me the tweeter sounds great....and wide range of control now with the 16 ohm / 50 watt l-pad.  Woofer volume is super low....

    I have the 265 coil, two capacitors in the little ‘wallet’ underneath it all.

    I do not have caged tweeters....or markings across the woofers.

    i think if I fully understood the diagram.....it will work fine.  Or....maybe I followed it properly and it won’t work.  Honestly not sure....

    i cannot post pictures....I’ll figure out how and post some.

    Thanks for the response..

    Well....I see that this is an old thread, so I’ll see where this goes....

    i was using these diagrams to rewire my AR 4x’s.....something went wrong.  I have very little output through the woofer.  However, the Tweeter livened up and I now have control (new control knob).

    i guess I did not understand the connections to the pot and then out to the tweeter....first.  And then the placement of the 24uf capacitor.....

    i became frustrated put it all away a few days ago.....I would like to get back to it as soon as possible.

    actually was just wondering if either of these two posters are still around to help.
