    Default POLK AUDIO - Speaker Parts List

    ***PLEASE DO NOT POST IN THIS THREAD***WORK IN PROGRESS***

    DISCLAIMER: Here are parts lists for the most commonly modified Polk speakers. Treat these lists as a guide, not as scripture as there were many transitional and variant Polk speakers sold. The list is for a single speaker; double the parts if you are modifying both speakers. Also, only capacitor, resistor, and inductor parts are listed. Polyswitches and bypass capacitors have been omitted due to the fact that they are usually not replaced when modifying or upgraded most classic Polk speakers; even though inductors usually are as well. Please double check all parts lists and schematics against your actual speakers before you order parts or start modifications.

    If you have any questions or comments, or would like to request a parts list be added, email me at zcables@gmail.com.

    Thanks for the list, that's great info...

    The question now is some of those parts have MUCH greater LONGEVITY than others? So if you're running some of these 15-20+ year old speakers? Which of those parts would you need to replace first and which probably last, almost 'forever'?

    The specs above are for a Monitor 7 series2, not the Monitor 7C. See below URL for Monitor 7C and earlier which only have two caps.

    +1 on CSi A6, not sure what is the middle yellow component is...
    it reads 0.47J100V Met

    I assume it's a capacitor??

    Other components for stock CSIA6 is:
    5W2RJ (2 ohm resistor at 5W)
    5W3R3J (3.3 ohm resistor at 5W)
    82UF / 50v BP
    8.2UF / 50V BP
    12UF / 50 V BP
    TV.......................Samsung 46" LCD LN46A550
    A/V Receiver.........Yamaha RX-V3900
    Amplifier.............. Emotiva XPA-1 Gen 2 for fronts, XPA-3 Gen 2 for center and Surrounds.
    BluRay Player.........Sony PS3
    Fronts...................RTia9 (modded)
    Center.............. ...CSiA6 (modded)
    Surrounds.............Empty for now. But waiting for a Fxi A6 deal on polk ebay.
    Rear Surrounds.... Deciding if front presence is the way to go instead.
    Sub..................... SVS PB12-plus/2

    Are the parts for the RTA-12C's the same as the 12B's that are already listed above? I want to upgrade the crossovers on my 12's and want to make sure I have the right caps/resistors.

    Thanks!

    Monitor 50 Series II
    Crossover
    8 uF 50V Capacitor (CRAP!)
    9.1 uF 50V Capacitor (CRAP!)
    Res .5R 5W * 2 (Ceramic Wirewound)
    coil 1 is .15mH
    coil 2 is 1mH
    and there's 1 small mica caps that I wasn't able to see the value

    a bit off topics but I have replaced the 2 bipolar cap with those

    CAP 8.0UF 300VAC METAL POLYPRO Digikey pn 495-4140-ND
    CAP 9.0UF 10% 750V METAL POLYPRO pn 495-3024-ND

    (HAD to take this 750v monster since nothing else was stock)

    those are expensive AC (unpolarized) caps that should sound
    better than pico sized electrolytic...

    so far I am quite pleased with the result, they sound MUCH better!

    Here's 2 pic that show how small the bipolar caps are in those filter...

    It has been almost two years since I did my 12C's, but I IIRC they are the same. Easy to check the top Xovers, the bottom ones are attached to the interior side of the binding post cup. Remove the 4 screws and pull it out, or remove PR and have a look. Always good to confirm the "official list" with what's actually there.
    "Science is suppose to explain observations not dismiss them as impossible" - Norm on AA; 2.3TL's w/sonicaps/mills, polyswitches removed, Lg Solen inductors, RD-0198's, MW's dynamatted, Armaflex speaker gaskets, H-nuts, brass spikes, Cardas CCGR BP's, upgraded IC Cable, Black Hole Damping Sheet strips installed on back wall behind MW's & Tweeters, interior of cabinets sealed, AI-1 interface with 1000VA A-L transformer
