***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.

    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.

    Hi, Just read your post on the Polk forum about the parts list for the different speakers. I am thinking about rebuilding the cross overs in my Monitor 5’s and my 5 Jrs. Do I only need to replace the capacitor, or do I need to replace the resistor and inducers as well? Are there recommended components which would be an upgrade to the originals?

    Thanks for your time.

    Hello Gary,

    Recommend to replace the capacitor(s) (Sonicap used most frequently, perhaps Dayton on a budget) and the resistor (Mills 12-watt). No need to replace inductors.
    If your model has a polyswitch, I believe Polk may send you some replacements free of charge, but not sure about that. Soniccraft.com has a bit of a sale on the Sonicaps (Gen 1) and the Mills. If your speaker has the 34uF cap, the Sonicaps get a bit pricey so some use a 33uF Dayton or Jantzen in this position.

    You will get more action on your question if you start your own new thread, please consider doing so to get more opinions! Click "New Discussion" at upper right of page to make a thread.

    Good luck!

    Series II CS-1 center speaker.

    The main drivers (W):
    iron core inductor is .68 mH[removed & measured]
    13 uF shunt capacitor to 5W 11 ohm resistor to ground

    Tweeter:
    - 8.22 uF (total) series capacitor [8.0 electrolytic and .22uF mylar]
    - 5W 0.5 ohm series resistor
    - air core inductor not measured

    From parts express:
    -- 8.2uF = precision metalized polypropylene film caps [6.8 + 1.0] + .47 uF film and foil

    -- 13uF = standard 5% metalized polypropylene film caps [12uF + 1.0uF]

    --0.68 mH air core inductor

    The two main drivers are in series with each other. These are shielded magnet construction.
    [When will shielded speaker construction stop? No need with flat panel TV's/]

    Internal wiring is very thin.

    PCB etch side PC-2004-01
    Silk screen side CS1 RE1515-1

    Original inductor axis were oriented at 90 degrees to each other as expected.

    -- 13uF = standard 5% metalized polypropylene film caps [12uF + 1.0uF]

    It's always best to split the values as evenly as possible. When you combine a large value with a small value, the small value acts as a bypass cap, which are to be avoided at all cost.
