    Default Polk Audio SDA SRS 1.2 Crossover Modification Thread

    I have been wanting to do one of these since I started doing this so this will be fun!

    Clarity Cap ESA (Tweeter) SA (Woofer/SDA), Mundorf Resistors, GIMPOD boards, upgraded SDA inductor, NL2 SDA outs (owner has a dreadnought), upgraded binding post

    Will be fun! :)

    Why the NL2's?
    Is it because your customer's dreadnought is already setup with them, or do you find them to be superior to a good set of binding posts?

    NL2 fits in the old SDA connection better (its larger than the original hole) and I find the connection be far superior to binding post, IMO.

    Are they tl's? Or are you going to do a TL mod?

    We are not doing a TL mod - the SL2000 is going to be replaced with RDOs

    For the cost of replacing the two inductors on the board and using the RDO-198's is a no brainier IMO...

    The biggest concern was wait time and after talking with Polk's CS we felt it would not make a big enough difference considering we were using RDO replacements.

    Better order mine now since it will be about 2-3 months when I do the crossovers.

    Just laying them out like that is a job in itself, and another fine example of why I hate you!

    For those not in the know, I am just ribbing Trey, but only because I am jealous!
    There, I said it, you happy?

    Hmmm, SDA inductors will be here eventually - going to ship using the stock inductor for now :)

    Just gotta do the SDA cables and Nl2 connection on the plate, test, pack, ship!

    Do you use zip ties instead of hot glue for later replacement?
