    Wtd Aquarius 4 xovers?

    as a newcomer i realise this is not about passive xovers but xover geeks maybe the place to ask for pointers.

    i believe i need to repair the xovers. if any readers have a reliable pair or a pair for me to have as spares do let me know

    salut

    I believe that you're best off to make up a pair using newer parts ( rather than waiting for a reliable pair to appear ).

    You can buy parts in the UK from someone like Blue Aran

    Here's the schematic ( included within ) the Tech Sheet for the S109

    Your le20 tweeters can also be replaced by le25 or le26 tweeters if need be.

    Troels Gravesen on his site has published lots of good info on these vintage JBL tweeters.

    I notice that on the tech sheet the recommended replacement is 035 TiA.

    Plenty of aftermarket versions of this here can anyone vouch for the quality ?

    also copy le25 here

    Hi Mac,

    Since I have no purchasing experience from the UK, where do think is the best place to buy network parts ( for a UK citizen )?

    I can locate genuine Le20 on the bay but obviously old, most have some indication they work with multimeter readings etc

    Thanks for ths very much

    I sill havent got access to inspect the xovers

    i dont want to HaVE to go down below the woofer rather than simply unscrew the xover board.... which maybe bigger than the actual hole....

    I have unscrewed it that but the board is glued in very tightly and sealed

    Whats the blockage ? Is the input panel not budging.? A sharp knock with a bit of wood impelled by a hammer placed in one of the corners

    I doubt that the factory glued them but AN other may have done so along the road

    Well the dealer may have sealed them up when refoaming etc took place as there is clear glue/ sealant all around the join between cab and input panel

    So no,its not budged a micron..but I will go and have a go the noo
    Such encouragement to get robust is so helpful, i have no sense of fragility etc yet

    Ta da

    Im in... its sunset here so more tomorrow

    What i realised is that one has to undo all 6 screws around the panel and not the 4 which look relevant with the lowest 2 some 6 inches away

    but they dont look connected to the panel logically..

    cheers Macaroonie

    Ian put a shout out on the forum marketplace. There are plenty of members here with serious squirrel tendencies.

    I'd be willing to put money on there being at least 20 pairs of working 2108's lurking in boxes in cupboards.
