How to replace a PSW10 plate amp?

A month ago, a lightning bolt hit the power lines outside my house. Thankfully, none of my major electronics were affected (as they were all on surge suppressing power strips), but my PSW10 sub was not and the plate amp blew out.

I replaced the fuse on it, but as soon as I replaced the fuse and plugged it back in, the fuse immediately blew again.

My suspicion is that the speaker itself is still good. How would I get a replacement plate amp?

    If they have an amp for that sub it's likely to cost more than the sub is worth.

  • Yeah, that's what I was worried about. I don't wanna pay $100 for a replacement plate amp. I can get a new PSW10 for $100 on Amazon...

    I suggest you aim higher as you will get a better sub.

  • That may be true, but I don't really have a need for a sub. I had it hooked up along side what are currently my computer speakers (Polk Audio Monitor 40).

    The Polk Monitor 40 and PSW10 sub were my "starter" living room speakers, but I upgraded.

    Guess I'm just going to toss out this dead sub then. Seems like such a waste, tho...

    What are your upgraded speakers?

    Yes if your speakers can get into the 50s hz then the psw10 isn’t helpful at all. The one advantage for HT is that it does give a little extra slam in the 40-60hz range, and you can control the volume separate from the speakers. But it also chuffs and gives no real bass to speak of.

    If your budget is really limited but you still want a sub then the psw505 is far superior.

    Not worth the cost to repair in my opinion too. You can probably find the same sub on your local craigslist for 40-50 bucks.

    If you feel like you don't even really need a sub for that office setup, why fix or replace it at all then ?

    Because it was the sub for my Polk Monitor 40 computer speakers. I don't really need a sub for them, though. I mostly just listen to music on my computer speakers.

    It just feels stupid throwing away a perfectly good speaker cabinet and sub-woofer speaker. And I don't feel like spending 5 hours diagnosing the problem with the plate amp.

    I'd rather replace the amp with a cheap refurb. I guess I was just raised to fix broken things, rather than throw away and buy new...

    Yes if your speakers can get into the 50s hz

    A pair of Polk S55 tower speakers. They get sufficiently deep for my listening/movie-watching purposes.

    The specs Polk publishes are deceptive as they list the overall frequency range, not the much more important -/+3dB spec. So, the overall low for the S55 is 32Hz, which I guarantee is about as loud as a mouse. I would venture to say the -3dB point is the high 30's. Most music has content into the low 30's and some a bit lower. While the S55 has more bass than your busted sub ever did you are still missing the bottom end, which really does fill out the music.

    For movies you'll want a sub that hits at least into the low 20's.

    From an independent reviewer....
    The S55s also did a good job with the tone of the viola, but I didn't feel the full heftiness of it until I brought in my SVS PC-13 Ultra sub.

    I agree, but I do think it depends on both experience and bass proclivities. Robert reina from stereophile (rip) often said that a speaker had to have solid output to about 55hz to be satisfying for most music. On the one hand I agree, as in a near field environment or a small room the trusty rt25is are pretty satisfying. BUT once you hear truly full range speakers (well down into the 20hz range) it’s really hard to go back...on the other hand, bass heads like @EndersShadow would probably never be happy with 55hz. That’s what I mean by bass proclivities...
