I replaced my rubber foam surrounds for the subwoofer using some I purchased from eBay for about $10. This was a few years ago and they are still working. Thanks for the original post!
Hey everyone! I made this thread back in the day to try to help folks out. I haven't been back to this site in a while - good to see people are still using this!!!!
Wanted to update everyone. I am still using my speakers. I use them connected to a laptop docking station in my home study. Last night, while listening to some bass heavy music, one of the woofers failed. The foam surround literally crumbled.
I just got off the phone with Klipsch. Although they don't make the 4.1 system anymore - they apparently make the 2.1 system, and the woofer drivers used in the 2.1 are the same as those used in the 4.1. So I ordered two of them! They should be in my hands Thursday. I'll replace both drivers in the subwoofer.
The total cost, shipped was $49. Not bad for a 17 year old system driver replacement. The guy told me they have upgraded/changed the driver surround material so the new ones should give more use. If I get another 17 years, I'll be happy.
I'll try to post here more.... HardOCP was the shit back in the day.
