    Default RT1000P - schematic / troubleshooting?

    Hello.

    I recently picked up a pair of RT1000P speakers secondhand and am very pleased with their sound. However, last week in the middle of a movie, one of the subwoofer amps suddenly stopped working. The main non powered 5.25" speaker and tweeter continue to operate fine, however.

    The power light is no longer coming on, and I have only been running these with separate RCA sub cables so far to provide signal to the sub.

    How can I go about getting a wiring schematic for the amplifier / backpanel connections for these speakers??

    Any suggestions on where to start?

    Thank you.
    Kyle

    If you do a search here, you should find some info on what to check first. I remember doing that myself, some time ago, when I was looking at a pair for sale locally.

    Hmmm. I tried to find some of those posts I read before, but no luck with a quick search. I seem to remember there is a fuse somewhere that you can check to see if it is blown. It isn't necessarily expensive to fix IIRC (unless the amp is blown), so, if you get stuck, follow Ben's advice and contact Polk's excellent C/S.

    For repairs, you can remove and ship the amplifier to them in San Diego (I think) if necessary, or they can ship parts to you (if the problem has been identified, that is, and it's a DIY fix).

    "often" the fuse in right underneath the IEC - good luck.

    I checked the fuse - unfortunately, it was still good... :(

    I've been in touch with a good guy (can't remember his name right now) at the repair center in San Diego. He's trying to dig up a schematic and provide some quick checks I can do with a multimeter. It was definitely nice calling a number and getting to talk to a knowledgeable person without wading through tons of automated menus. Big thumbs up so far.

    He told me I can get a replacement amp for what seems to be a reasonable price, but seeing as though I only paid $150 for the pair used, I'm hesitant to sink in much more $, especially when the sub in the other speaker still works, and they're only used for an outdoor movie setup that gets used once a month or so.

    I'm kicking around just wiring the 6.5" speaker directly to the high level banana plug inputs, but am concerned about impacting the overall resistance seen by the receiver. Thinking back to physics, it seems that if I wire the two 8 ohm speakers in parallel, this will give me an equivalent resistance of 4 ohms (1/8 + 1/8 = 1/4). If I then place a 4 ohm resistor in series with this combination, the equivalent should be back up to 8 ohms. Is this logic ok or flawed? Just tossing out this idea... Not looking to do anything stupid here, but thought it would be a good place to ask.

    Spoke with Art Martinez from the SD service center on 9/24, haven't heard back yet. Was expecting either something in the mail or a followup call.
