I'm using Pioneer S-W200 (Linear Power) Sub for my home theater system's bass responses. Its a kind of old sub which features 5.78" drivers x 2.

However I'm experiencing some annoying problem with it. When on deep bass, especially on movies, I'm getting the heavy bass tone, however also I'm hearing a very powerful speaker's paper flickering kind of noise. It was somewhat like speaker tries to come out of frame. Check the youtube video please.
If I lower the overall sub volume this flickering disappears however with the bass also. Turnover has set around 100Hz, can go up to 200Hz. And the feeding is done by Reviver's sub-woofer speaker out to speaker inputs of subwoofer.
There's an RCA input also for this sub, however if connect my receiver's preamp out, the bass tone gets very soft and has very low decibel level.
Can anyone suggest how to fix this flickering sound please?

Are you the original owner? To me, it sounds like old drivers that the foam surrounds are shot on.

No, I'm not the first owner, I purchased this from an used goods store.

I also inspected the foam surrounds, However I thought thats the nature of this model? Some "linear" brand. not sure

The drivers don't look like they are functioning normally either, which is why I thought to mention the surrounds because the cones look like they don't have any the way they are jiggling around like that. Hard to tell from the video and my eyes aren't that great.

I've repaired worse (I couldn't afford new speakers) but they were my own speakers and I didn't play them once the foam fell apart so they didn't get injured further. With those being 2nd hand there's no telling, and you'd be taking a chance repairing them and it would help if they meant something to you or were worth anything to begin with.

The smart/safe thing to tell you would be to just replace it.

It sounds to me like the suspension is flapping around where excursion is over-doing the suspension. It might also be the tinsel leads hitting the cone. Neither problem is really fixable. Sorry to tell you this, but that sub was a junker from day 1. Time to get a big boy sub.

I have repaired quite a few drivers in my day and there are some commando fixes and ways to tell if you have a chance of improving them, if you are an artsy crafty sort.
Here are some that I repaired using store bought rubber surrounds.


I have also made cloth ones using linen and liquid rubber and a crude mold made from plastic plumbing tubing. Not because it was practical, but because I was bored.

All of these speakers I repaired still work and the ones above are still being used daily and these were done about 7-8 years ago. :)

Yeah, hate to say it(and sound like an echo) but as far as subwoofers are concerned, that wasn't much of one to begin with. Two small drivers with little excursion capability and lack of low frequency tuning and it was doomed from the beginning. I just can't believe the price tag. 800 bucks is a lot for it at pioneers site. Respectfully, I would suggest a new one.

Sounds like the driver itself may be loose, which tightening would solve. Secondary thought though, driver may actually have a damaged voice coil, and that's ultimately what it sounds like to me. Hopefully it, or something else inside, is just loose.
