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!

Bought the stereo 6 months ago, now the speakers won't work!!!! Please help!


Hi, when a speaker does not work, you might need to do some troubleshooting tips to know exactly where the problem is .

First you will need to test the speaker cone if it's working properly by using an AA battery and two wires to make sure the cone is working..

Connect one of the wires to the Positive side of the speaker, and the other on the Negative side, And after that use the battery to hear if the speaker cone will make a click sound.

If it doesn't make a click, that means the speaker cone is Bad, you will need to replace the speaker cone,
But if there is click from the speaker cone, that means the speaker is Ok, and you might need to trouble shoot your stereo to be sure if the sound IC chip is Ok in the stereo..

Hope it helped..

I have a set of technics SB-5000a speakers. one of them the 10" sub is blown. there is no resistance accross it. the cone is in good shape so i think it is the driver. normally you can unscrew the...


if there's NO resistance, see if the lead running to the cone (coil) has broken.
If so, you might be able to solder it back on and save the speaker.
Sometimes they separate at the terminals, sometimes at the cone.
If it separated at the cone, you may need to peel back a bit of paper to get to the wire underneath, and scrape the enamel coating off the wire so you can solder to it.

Otherwise, it's off to your local audio mart to buy a 10" whoofer at the same or higher wattage and same impedance. Take the old one with you to make sure the screw holes align too! (although that's not 100% essential as you can always drill new pilot holes wherever the screw holes aare....unless the screw holes have a metal insert)

If you did have to peel back some paper to do the repair, reinforce the torn area with toilet paper and fingernail polish. Use several layers as you don't want the movement of the whoofer to rip apart your solder joint or any more of the cone.

REPAIR CONE TEAR IN 18"


If the tear is large, or the speaker cone is brittle because of age, you might be best off having the speaker completely reconed. There are companies that offer the service, or you can buy replacement cones and do it yourself.

For small tears (an inch or so long), you can glue a patch in place. I have used a piece of a paper coffee filter as a patch, and plain white Elmer's glue slightly thinned with water. Put the patch over the tear and use a small brush to spread a thin layer of glue over it. Give it a day to thoroughly dry and you should be set.

I have found this repair to be more effective on smaller speakers than on large woofers, though. The woofer cones are more mechanically active. But I patched a couple of 15-inch cones that had been punctured for a friend, and they are still playing after a year. So it can't hurt to try.

What kinda glue do you use on a blown speaker?


A blown speaker needs the windings replaced and re-coned. If you have deteriorating foam\cardboard type edges you an use clear silicone caulk from any home improvement store to fix small tears or detererioration. Tears and such on a large scale will require re-building.

I blew out my car speaker. Can I fix it?


Yes you can if you >
The term blown speaker can have several meanings. If it was not fixable I would say it was a blown speaker.

So 1st is it a Subwoofer or a midrange.
The Sub a little easier to fix you can send it Back to the maker of the sub and they will fix it ($)
If the cone is damaged then just use silicon
if the wires + - that are attached to the basket and the cone have fried .Soilder a new coper wire on
If the voice coil has ripped silicon
and if the copper coil is melted (you can see it but the cone will not move in or out Frozen) then this is a good time to replace it

You can go online and see if there are professional Repair kits

Speaker cone pushed in


I just bought a pair of mirage v2s and was waiting for my receiver to ship out to me. Like a complete moron I wanted to see what the new material on the tweeter dome head felt like. Haveing no idea (due to the latest in speker technology and materials) how delicate they were I pushed in the tweeter cone. Now that your done screaming at me how dumb I am(mind you I have not even heard one note of delicious music come out of them yet...Idiot I am) Heres the fix.
Tried a magnet no good
Tried a small pin to penetrate it and the pull it out but didnt have the heart to poke a hole in it.

THIS WORKED THOUGH== Wrapped a pencil in electrical tape. (Warmed it in my hands a liitle first to make it a little stickier and to make it not stick to much) placed the taped pencil point on the damaged part of the speaker ,rolled it ever so gently to get it to stick and gave a quick but controled tug then pulled it very slowly to get it the rest of the way out. Whallllaaa it worked. Only a very small indent was left from where I tried with the pin. Stilll havent as of this writing heard them yet. Cant wait.

Orion subwoofer repair


A good spekaer repair guy could at least pull the cone out of he basket and have a look to see why the voice coil went open circuit. Sometimes they can be repaired. sometimes the entire voice coil can be replaced. Spider wires fatiguing are often the main culprit that make drivers with long extension to fail. Sometimes they are secured to the cone with contact adhesive, that it itself can corrode the braided spider wire causing it to go open.

I am sorry mate, but the only contacts I have in New Mexico that I found through your yellow pages, and because I know little about them, I cannot offer you a reliable refferal. I suggest you go(ring) to a decent proper HiFi store in your area. They will most certainly know of a specialist bloke that can do the work for you.

I know I cannot fix you problem over the internet(if you lived in Brisbane, Australia I would do it personally:)) but a FixYa rating would be great for my time to evaluate your problem and offer advice. Ring around a bit... I am sure you will find someone to repair the original driver. Good luck.

regards
Graeme
