in Speakers
Looks like running passive requires more effort than i have time for.


So i see ebay has amps. Is there an upgrade amp available now or am i stuck putting in another SA100 in it ?

    Just looked. $175 is a bit much for a replacement amp thats already what i consider a ****.

    I have a nice set of xovers from a pair of B&W speakers i need to look at. I can work around the stock amp issue even if not optimum. These are just experimental speakers i got for $150.


    I have all i need already just about.

    Worse that could happen is blow up a driver or xover i guess.

    You might want to consider having a local electronics repair shop look at the defective amp. Usually there's not a lot that fails in these designs, power supply filter capacitors, sometimes a voltage regulator. Nothing a repair shop hasn't seen before. If I remember correctly there was an eBay person who was repairing plate amps mentioned in the past.

    What's the problem with them? Most of the time the filter caps go bad, sometimes the voltage regulators do.

    You can always replace these yourself, or find a tech to do it for pretty cheap. Use Cornell-Dublier Electronics 105°C rated caps and you're off to the races.

    Running them passive is an option but the amps in these speakers are pretty darn reliable once you repair them. I recall that the capacitors in them were made during the capacitor plague but I'm not sure how it affected Polk's amps.

    I just got them last night. For all i know it could be a fuse.

    Im thinking the options. From what ive seen there isnt a lot to it so it could be fixed.

    I need to bust open the non working and see whats up.

    Have you even tested them to find out they don't work? If it's humming, it's probably just the filter caps. If there's no light, my guess is fuse.

    When i picked them up 1 was working 1 was not. I knew that when i went to get them. By that i mean the sub amps playing sound. I didnt examine anything

    Brought them home and put them in my office. I will check it tonight.
