    The black rubber ends that cover the JVC RV-B90 sub-woofers was cleaned using a household cleaner. Every since then the rubber has become sticky to touch. Any cleaning agent seems to breakdown the rubber surface. It now leaves a black residue on your hands when touched. Because it is sticky, dust and dirt stick to it. If you try to clean it with any type of cleaner, it becomes more sticky. What can be used to clean the rubber and prevent it from being sticky?

    Thanks for your suggestion. Before I read it I tried Isopropyl alcohol and some rags. It worked pretty well (not pristine but the goo is gone). It took a few rags and some elbow grease But I'm happy. Time involved about 1/2 hour per piece.

    Yes, I have the same problem with the rubber like coating on the knobs and End caps over the woofers. My unit is a RV-B90GY. The unit is new in the box. I got it out the other day and noticed the tackyness to where the coating was applied. This breakdown occurred in the box. It was never used. Called JVC and they were about as helpful as doors on a motorcycle. This should be a recall.



    To remove the goo you need to break it down further. I used Windex that has ammonia in it. Also used Isopropyl alcohol 70%. Sprayed windex on parts and let it stand for an hour. Scrubbed the knobs and end caps with the solutions and a denture cleaning brush until the goo was gone. Then used dawn liquid soap for the final cleanup. After parts dried they had a dull finish. Used Turtlewax auto paste to shine it up. Looks assume now. Hope this helps.

I fixed it perfect by buying some Motsenbocker's Lift Off Silicone Latex Caulk and Foam Sealent Remover from Home Depot and applying the gel with rubber gloves (also from Home Depot). Took off the sides of the boombox and knobs. Took about 30 mins in a stainless steel sink.
Then bought some Black Flat spray paint at Walmart and sprayed.
It looks perfect when all put back together.

Remover $5.00
Paint $3.00
Gloves $2.00
Plastic scrubbing brush to throw away after $1.00

I used 99% pure Isopropyl alcohol that I got at a local drugstore. It took lots of paper towels and Q-tips to clean off the rubber coating. It probably took about 30 minutes per end, as there are a few hard areas to reach. Once the rubber coating is removed it leaves you the greyish black plastic surface underneath. Now it is no longer sticky and does not get covered with dirt and dust. Also you no longer get a black residue on your hands when touching it. I am very happy with the results.

I also had this same problem. As recommended above, silicon caulk remover works marvelously to take off the sticky coating.

To be fair, cleaning does not take 3 hours of your own time. After a few minutes to apply the cleaner, you just let them sit around for 3 hours. (I even found that letting them sit overnight helped clean the large end handles thoroughly.)

I have AIWA NSX-RV85. The sub-woofer surround tore leaving just the cone. When I play, The woofer just makes a rattling sound coming out of vibrating cone.Any advise on how to fix my speakers.Thanks


Refit the rubber, you can find itbon eBay, its called reconing actually in this case the cone is the inlybpart wich you dont want to replace... The rattling is beingproducer due to the fact the rubber normally holds the cone ibto positionering over the coils. This rattling is not good can defect your cone. So dont play it roll you got a new rubber fitted!

I never used my 10sw klipsch subwoofer and it's not working.


Check the cone surround - unless it is a rubber butyl surround, the material self destructs in air after about ten years and the speaker will stop woofing.

The spongy rubber around the speaker cone has come away/disintegrated and of course they can`t be used. I also noticed the front spongy cover has disintegrated. Do I have a problem with bugs or something....


The foam surrounds degrade with the years. No bugs, just old age. If the speakers are worth it, you can have them repaired at better audio stores.

Does mmats sell the rubber surround for a 12 inch procast? one of my procast needs a new rubber. Do i have to sent it in or can i fix it at home/


You can do it yourself if your handy. Lots of places out there selling them. Not too bad a job. Takes some patience gettiog the old one off.. If its really rubber and not foam, it'll come off in one peice. Have to be carefull the get the cone centered when ya glue the new one in. If you decide to tackle it get one with instructions and/or a good web search on the surround replacement.

Diaphragm problem


Yes it can be replaced and your system will be as good as new afterwards.

To get an idea of the work involved: http://www.audiofriends.nl/pdf/refoaming.pdf

There are several companies selling these so called surrounds. There are foam and rubber surrounds. Stick to the same material as you may otherwise significantly alter your system's sound. Just google "speaker repair" or "speaker surrounds" and you will find several. You can ask them to repair your speakers (which may be fairly expensive) or you can order the surrounds and glue (you can not just use any glue) and do it yourself.

I have done such repairs a few times myself and it is absolutely not difficult.

Good luck.

Seals around speakers are broekn and gone!


Hello kagato_morri,

While it's certainly possible to replace the surrounds, whether it's economical to do so is another question. For very high-end speakers, there are often "repair kits" available to replace spiders, cones, surrounds and for some, even the voice coils. But such parts are usually not available for your run-of-the-mill speakers.

If the speakers are otherwise in good condition, and you are willing to spend some time with them, you can use an adhesive foam to construct a new surround. A product called "shoe goo" makes a good permanent bond. It's a super strong rubber cement and will hold up under the stresses of the moving speaker cone.

Hope this helps.
