    Default JR149 - Restoration Thread

    I always wanted a pair of LS5/1A's but didnt want the price that goes with them so I bought a pair of JR149's.

    They work but the cross over's needed recapping. A quick call to Falcon Accoustics and several days later a package of new caps arrive.

    The old cross over (which was a bugger to removed) looked like this DSCN1262.jpg before repair. I had to use a small hacksaw to remove the threaded bar which lives in the speaker and gives the cabinet some rigidity, this will be refabricated later.

    Andy:
    You should not have any trouble removing the X-Over if you remove the 'B110' Bass unit & hold the Threaded stud from inside while undoing the nut

    Try telling that to my speakers, the nut's (pardon the expression) were jammed solid. I have some threaded steel so it's not going to be difficult to replace. I might do a little rewiring ( I can always store things), and move the X-O further away from the speaker and implement some proper female RCA sockets. I'm just taking my time and enjoying the tinkering!

    I was going to say that.

    Unless someone previously has cross-threaded the end section.

    Well its raining in Wakefield, so what better way to spend 15 minutes than updating this thread.

    I have now removed all the old caps from both the X-O on the 149's, here's a picture of, these will be stored as spares.



    Here's a pic of the BASS driver verifying the type I own, this and the tweeter will be measured at some point to see how healthy they are



    Lots of crappy old glue from the original foam coverings. I'll clean this off at some stage.



    A little time later and the new caps are now installed on the X-O.



    Oh my GOD that foam needs replacing!!!!!




    Final verification of the X-O I've been working on. Check out the pink tacky stuff that was used to hold the X-O in place, which needs removing.



    OK, need to buy some supplies for next stage of restoration.

    Toodle pip!!

    You'll find that crappy old glue is from the adhesive around the hardboard top, id leave it.. I would not worry too much just new top & bottom circular boards, New Grill & rebuild/rewire crossover. I wouldnt spoil the bottom cans trying to apply Binding post..

    I think someone used to sell a selection of different veneered boards for em..

    There a 'JR149' sub for sale in the Netherlands if your interesturd?

    The grill's (steel) are in perfect nick. I'll probably do a silver rewire and save the old cable. I was hoping to repair or re-veneer the top and bottoms. The very base of the speakers is scratched and has a little rust so this will need some attention. Maybe some pics tomorrow.

    I didnt mean the aluminium grills that are stapled on to form the front.. i meant the foam grills that wrap around.
