A week or two ago we were visiting friends and I saw a subwoofer sitting out by their drive in the snow. I asked about it and was told it made awful noises. I "adopted" it and brought it home, and found out the foam surround was falling apart.
I found this kit on amazon
and ordered one.
I did the repair yesterday and used the sub last night to watch some bass-heavy movies (King Kong vs. Godzilla anyone?)
Anyway, it came out very nicely. It's my first attemot at a speaker repair.
The hardest part was cleaning the old glue and schmutz off the outside edge of the speaker frame, which took about 3 hours. Then a series of glue-ups:
- Glue new foam surround to speaker cone, dry 1 hour
- Glue new foam to speaker frame, dry 1 hour
- Glue the gasket, wherever it delaminated during removal, dry 1 hour.
- I used RTV instead of the provided glue to seal the gasket on the speaker atop the new foam, since it looks like these foam surrounds are a primary failure point for these speakers. Hopefully RTV will be easier to separate than the 'airplane glue' provided with the repair kit.
It's worth trying if you use reasonable care and have a bit of patience.
The PDR-10 sub performance surprised me. For a ported 8" sub it goes pretty low. It rolls off by 10 dB at 28 Hz. It won't handle Earth shattering dB levels (it sounds like the cone breaks up if you push it too hard. Can't expect too much from an 8" cone and a 100W amp.) but complements a living room surround system pretty well.
