Re-foaming a 15" Cerwin Vega with 10Hz Test Tone 

I find most of mine locally on Facebook Market Place and other local buy and sell sites. I also frequently shop around at pawn shops and second hand stores. Most of their speakers especially the larger 15 inch models are heavy and cost lots to ship, also the risk of damaged during shipping makes it not worth it.

The 2 midranges might be saved by carefully using a vacuum cleaner to suck the center of the cones back out, this works on dust caps as well.

The type of material used for the surround on a woofer plays a big role in its T/S parameters. CV used foam because it is lightweight and allows the cone structure to move with very little resistance. The foam is one of a few reasons their woofers have a very quick transient response. Most rubber I assume would have a negative impact on the woofer.

@@SavingVegas What i meant to say is i had the Vegas replaced with Mtx woofers with rubber surround

@@ronkali5365 Rubber is fine for subwoofers and for normal speakers. But the foam is superior when it comes to those transients.. Check out one of the worlds most expensive speakers, they use foam just because of that rapid moves. Magico.

If you center them good no need to. You go by feel after and adjust while glue still wet. I just did mine and all is good. Thank God.

This is correct PageCrowes. I uploaded a video a while ago on the importance of shimming the voice coil, this is however mostly for people who don't have a ton if experience working with woofers. I have refoamed and reconed many, many woofers and midrange drivers before so I am very confident in my ability to center them properly without the use of shims. I also have ways of checking them as the glues sets to confirm they are set right. This of course depends on the driver I am working with because the voice coil gap varies from one to the other. I see it as a benefit doing it this way by not removing dust cap and having the possibility of foren debris making its way into the gap. When people make negative comments like darrelldarrell1447 here I can only assume they have little experience doing this or knowledge of the actual quality of some CV woofers. All good though, each to their own, sometimes people feel they need to post comments as such to make them feel better about themselves. Makes me wonder why he was watching this video in the first place 🤔
