PSW300 woofer repair/replacement help!

Wendelman

Hey all,
I have browsed through a few of the older threads covering PSW300 problems and repairs. My 300 has the familiar rattle, and I have had it in storage for awhile, but now I finally have the time to repair it. So I was just looking from a little guidance from those who have been down this road!

For starters, what is the best way to open up this puppy? I see screws going up through the leg pegs, and on the amp of course. Which is my best starting point?

Then, does anyone have any advice for attempting the "spider-glue" repair method, or opting for a new driver? The box is in great shape and she worked perfectly until I must've over-extended her limit watching Underworld a few years back...

This brings me to my most urgent inquiry, I just stumbled upon this driver from a PSW202 which I have heard works great in the 300 with minor fitting mods. I have also heard that these mods are a little more that "minor" and can be frustrating! Here is the link to the ebay auction, but it ends today!: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150630593426&ssPageName=STRK:MEWAX:IT

I have also found a good selection of near OEM spec drivers from a seller named "mavin". here is one of his that I was looking at: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250705081749&ssPageName=STRK:MEWAX:IT

Thanks for looking, please help if you can!

Does Polk no longer carry parts for service??

Wendelman

I have not contacted them yet...but I have heard that the original MW1081 driver is no longer made/stocked. Have you had any problems with yours?

You can send the MW1081 to us and we can *usually* repair it.

Ok, thanks Eric. How does that whole process work (cost, time, etc)? Also, what is the best way the open up the cabinet and remove the sub? I am guessing the amp needs to come off first but I wanted to make sure I know what I'm doing before I start taking it apart!
Thanks

Bump. Anyone have any experience/advice for opening her up? Also, I have been looking at a few replacement woofers on eBay, which one of these looks to be a better match?!

Hello,
It should be fairly straight forward to remove the 10" woofer. Remove the sub's grille cover and take out the screws that go around the circumference of the woofer. You might need a putty knife to loosen up the woofer from the cabinet, go around the circumference much like you take off a paint can lid. Once removed the connecting wires have metal clips that pull off of the woofer's terminals.
Box it up and send to Polk for repair.
Regards, Ken

Ken,
Hey thanks for getting back to me, but the PSW300 does not have the exposed vent that the 350, 450, etc have. The 300 is a complete box, with a down-firing vent. Here is a stock photo:

It looks to me that removing the amp would be the only option as a starting point...but I also doubt the woofer will be able to fit/maneuver its way from this opening! Any ideas?

Hello,
Ah, you are absolutely right, the woofer is mounted internally. I'm sorry for the miss-information. Remove the amp using the same technique I described for the woofer and you will be able to remove the woofer.
Cheers, Ken

Hey, thanks so much, I will work on it tomorrow. I'll let you know how it goes then.
