I finally got around to repairing my DXM6 mid ranges for my VS 150s. I gotta say thank you for this video because without it I never would’ve been able to do it. They both turned out much better than I thought they would. As a matter fact, they sound brand new. The voice coil rub is completely eliminated. The only thing that I’m not happy about is when I took the surround off of the basket, I stretched the surround a little bit so when I glued it back on, it wasn’t a perfect circle, it has a few lumps in it, which is not a huge deal because the grill covers it, but it is what it is. Thanks again for your videos. They really do help.
thanks for the details! I have rebuilt a few speakers some better then others - but the time lapse stuff you put in this video gives people a good idea of how to take one apart. Thanks again love vega's!
I'm glad you enjoyed it. I started doing some if my work I do in the videos in time laps other wise the videos would just be too long. I didn't want to leave it out because that's an important part of the whole process. For instance that 3 to 4 min time laps was over 90 min of footage originally. As for details, we'll it's all in the details when doing this kind of work. I figured if I was willing to do it someone else would be willing to as well so why not put it out there. Thanks for watching.
Well well well look who is back. I thought you signed up to go to Mars. Consider the quality standards when originally produced as well. Nothing is perfect. Han Dong may have had a upset stomache or a tooth ache that day.
Some people turn their noses up at measurements and I think some take them a little too seriously. I believe their important when doing any kind of repair work to a speaker. Changing vital components of a driver can drastically change its parameters and you need to make sure after the change that the driver is still going to work together with the speakers other components. I don't use measurements to judge how a speaker will sound because a frequency response doesn't tell you everything, it can give you an idea but not the while story. I use them to detect major issues if any and go from there. I'm glad you enjoyed it and thanks for watching.
@@SavingVegas Totally agree. I'm an engineer so I love to see the data and correlate that to if a perceivable difference is there as well. I would love to see before and after measurements taken on your crossover upgrades if you ever get the chance! Thanks for all you do to get information out there, I've learned allot from your videos.
That's awesome. I have lots of fun tinkering with this stuff and have been doing so for a long time now. I have already taken some initial measurements of this speaker and that includes each individual driver as well. I have compared the initial measurements I took with the crossover inline and the midrange frequency response doesn't look much different than the ones I took of the mid unfiltered. I have yet to remove the 2 capacitors in the midrange circuit to test their values but I'm guessing they are going to be out a lot. There are also 2 inductors in that circuit as well so my guess is that's all that's really filtering that mid right now. There's a good chance I will be making a video on these crossovers. I have all new parts for them, polypropylene caps and air core inductors but I may be using them in a different set. Either way these are going to be getting new parts but probably cheaper budget parts otherwise I am going to be into these for more than I can sell them for.
Just watched your video from beginning to end a couple of times. I received my spiders and dust caps and adhesive yesterday and I plan on doing the repairs this weekend. I really hope I’m able to do this because if I am able to, I will be saving 3 DXM6 mids from going to the landfill. Just one quick question if you don’t mind… What did you use for the shim? I’m not exactly sure what I should be using for that and whatever it was you used looked pretty thin.
I have a pair of CV 120VS speakers... bought them from Circuit City in the early 90's... The foam has deteriorated after the years...are you able to restore them? woofer and mids...?
Replacing the foam surround on a woofer is a pretty simple and common repair. There are many speakers that use foam surrounds, some still do to this day. Many shops that repair speakers will be able to do this, and it's not an expensive thing to get done either. The midranges on the VS120 should not need this done. They should have a treated cloth surround on them.
Unrelated question for you sir. What glue/adhesive would you recommend for loose port tubes in a VS120. Both tubes in my one cabinet are loose. Thank you in advance for a response.
I generally use a product called PL Premium, it's a construction adhesive that comes in tubes to use with a caulking gun. If your just gluing the ports back in that may be a little overkill, even just a good wood glue works just fine for that application.
I know the VS120 uses a different midrange, but have you come across the same issues with the VS120 midrange? Great video thanks! I recommend using a nice spray dampening material on the plastic midrange enclosure. I know not factory but it’s a harmless modest modification
The DXM-4 used in the VS-120 and ATM-5 used in the VS-100, AT-10, 12 and 15 don't seem to have the same issues. They are smaller drivers with less excursion so that may be why they hold up better but I can't say for sure. The crossovers in these 150s were in rough shape, both capacitors in the midrange signal path were toast. Good chance that was the cause of the problem with the midrange driver. The caps were no longer keeping the mids from playing outside of their abilities causing extra stress on them is my guess. As for your suggestion for extra damping on the mids enclosure, that is a great upgrade. That and even building a more solid one using MDF or similar material as well as the extra damping you suggested.
Where can I buy those spiders? I have a pair of VS 150s and both of the mids have voice coil rub. I plan on using your video in order to help me repair both of my DXM6 mids. Appreciate the video!
The exact ones I purchased are unfortunately not available anymore. But your basically looking for spiders that have a 4 or 4¼ inch outside diameter and a 1 inch center diameter for the voice coil. Some of what I didn't show in the video is the R & D I did to find the best suited spider. What I found was a little stiffer spider worked better than a more flexible one. Either way any new spider you get within the size specs will be an improvement apon the old used ones so you should be good to go.
@@SavingVegasthanks for the info. Going to order some spiders, and epoxy etc. I have I good midrange in one of my VS-150’s, and I have a blown one in the other, along with 2 other blown mids I bought on eBay. Hopefully your video can walk Me through repairing them.

Just inherited a pair of CV's from an uncle that recently passed. Forgot to grab the model numbers but, glad I found your channel. BRB

i like every one cerwinvega speaker ever made including the sl 5

@@SavingVegas Yeah that's super surprising no measured difference with those old caps in there. Looking forward to your future updates!

Hey, I have a set of Cerwin Vega VS12. Do you by chance offer a service to provide a completed drop in crossover replacement? With delivery to Europe.
