Do you own a JBL Creature II speaker system? Have you noticed that the satellite speakers aren’t as loud or balanced as they used to be? Wondering if it is possible to fix them? If so, here’s the answer.
The JBL Creature II satellite speakers have a paper cone that wears out over time. Even if it doesn’t get abused by humans or pets the material will eventually deteriorate and then splits will develop. These splits will slowly get larger and larger. Since the splits allow air to pass through them, that means the cone will leak and the affected speaker will get quieter over time as well. The chances are that one speaker will deteriorate faster than the other, in which case the balance of your 2.1 stereo system will drift to either the right or left. You can compensate for this — for a while at least — by adjusting the balance via the operating system’s sound controls. Eventually though, the damage will be too severe.
If you find yourself in this situation, don’t worry. It costs peanuts to replace the core internals of both speakers and return sound quality to an ‘as new’ condition.
Just search for a pair of 4 Ohm, 5 Watt, 40mm diameter round speakers on eBay. A number of vendors sell them. I bought these ones for less than AU$10: https://www.ebay.com.au/itm/152881540850
The original speakers are a bit smaller, and fit into a custom white housing (shown in the above-right image). You’re not going to be able to find an exact replacement. Not to worry, though, as you can just glue the replacement speakers directly onto the black plastic socket that the housing was extracted from. That will all make sense once you disassemble a speaker — a trivial process.
A number of YouTube videos detail the repair process: https://www.youtube.com/results?search_query=repair+creature+ii+speakers
So yes, you can fix your Creature II satellites for only a few bucks each. No exotic equipment is required. I used a small screwdriver, a small pair of pliers, and a hot glue gun. Took about 10 minutes each. Easy peasy. Have fun!

Hey, glad I stumbled across this, one of mine died, had a spare set, was in the process of replacing the tweeters again… then the old replacement got messed up during install! Thought all was lost so will give this a go. Just looking for the right size units now.
You shouldn’t have a problem finding a set. The search term “4 Ohm, 5 Watt, 40mm diameter round speakers” will serve you well. The Creature speaker set is a really, really nice one — well worth the effort of repairing and keeping in service as long as possible.
