How To Fix a Woofer With Voice Coil Rub 

Thanks! I am too. The time sure flew by but it felt good to get some more content out there.

That's an excellent point. If there's very little tolerance for the coil gap, I can see how that could affect it. I installed this woofer into a few different cabinets prior to this repair. The first was the original 211 cabinet, in which the woofer actually gets mounted from the inside, and the other was in a VS-120 cabinet. Either way, the coil rub was the same.

The Yamaha NS-690's are great speakers. I had a set of the tri amp versions for a little while but sold them just because I got a hard to turn down offer for them.

I don't know about amazing but thank you! Always good to know when people enjoy the video.

The RadioShack replacement woofers are pretty common to find in the older CV speakers it seems. A low cost replacement woofer seems like the best option for people who are unaware that replacing the foam surrounds is fairly cheap and easy to do. The reason that lots of the factory woofers have been tossed in the trash unfortunately. Your not wrong, finding somr 122S4 or 122W4 woofers may not be easy but they do pop up every once in a while. Both of which can be reconed as the proper 122S4 4 ohm woofer. If you ever do come across a set and they need to be reconed Brew City Audio LLC is the place to get the proper kit. Unfortunately I can't help you much on where to find some other then always checking Ebay and any other places for a pair to come up. Good luck I hope you end up getting some and get them rocking again.

Problem with the products from most places is they are made to be a one size fits all. Which in most cases isn't a problem but CV made many changes along the way and weren't very consistent. Brew City Audio has excellent products specializing in Cerwin Vega foam kits, recone kits and more. He sells on Ebay and customer service is by far the best as well as his products. Just look up Brew City Audio in sellers on Ebay. It's the only place I get my parts from.

The crossover is most likely the culprit. If they were abused and had gobs of power thrown at them for extended periods of time it is possible it could have overheated a component in the xover causing loss of signal to the mids.

That's a great idea, does anyone know how I can contact saving vegas as I have an idea that would help me and maybe make him some money. Looking forward to seeing the full rebuild. Good day.😊

Hey there, you can E-mail me at savingcerwinvega@gmail.com.

Those are R24's

I've been eyeballing them since they were released. Sounds like they are getting good reviews for the most part given their price range.

@@SavingVegasthey will be releasing the LSD series next. But it’s still a narrow baffle design. We all need to get on them to make a modern big woofer 3 way.

I have a feeling they never will but you never know 🤞

The 6 ohm rating is for the entire speaker and it is an impedance rating. The impedance changes depending on the frequency that's being played through them so think of the 6 ohm rating as kinda like an average over the 20-20,000Hz frequency spectrum. If the coil is damaged on the one you can use your multi meter to check the resistance of the other working woofer (woofer only). If the meter reads around 3-4 ohms it's generally a 4 ohm and if it's higher let's say around 6-7 ohms then it's an 8 ohm.

Awesome. Thanks for the help. I enjoy watching your videos

You welcome, always here to help when I can. I'm glad you enjoy the videos, lots more to come yet!

The most common part to degrade first is the foam surrounds used on the woofer. There are no new VSW-15 woofers available to purchase anymore and I highly recommend getting the foam replaced before trying to replace with a different woofer. The passive crossovers are designed specifically for the original woofer, midrange and tweeter so using a different woofer can cause all sorts of different issues. If you feel replacing the foam surrounds is beyond your capabilities I recommend finding a professional to have it done for you.

@@SavingVegas Where you located. Thank you very much.

I'm in Saskatchewan, Canada

@@SavingVegas Very nice video, am from Boston. I appreciated thank you very much.

@@SavingVegas do you have a pair that I can buy it from you.

When running a 4 ohm speaker on an amp that's only rated as low as 8 ohms you are more likely to damage the amp not the speakers. Lots of people still do it but you have to make sure you keep a close eye on the amp as because those speakers may cause the amp to run hot. Some newer amplifiers will have a protection circuit that will shut the amp down before any damage can happen.

Ur amp will be fine u will have plenty of impedance rise to be at a safe ohm load for ur amp.

I fixed my AT-12's w surrounds from amazon & it went great & are more substantial than the stock surrounds

I sure would like to know if I can fix my dual voice coil sub that has one coil working and one that's not or at least that's the read I get on it by doing an ohms or resistance test

Awesome! Glad the refoam job was successful, enjoy those great little speakers.
