[QUOTE="John_E_Janowitz, post: 6121264, member: 550657"] Woven leads IN the spider greatly reduce the longevity of the wires and spider. As mentioned before they are formed with heat and become brittle, fray, and can spark up. There are many documented cases of this. The flat ribbon type leads on top of the spider are a good option if they can be attached after the forming process so the extra heat is not applied. A combination of sewing and adhesive is required to properly attach them to the top of the spider without them coming off after time. Spiders with any kind of lead wires in or on are not available in the US though. The only way to do it is to bring them from china, taiwan, or attach the leads in house. We're looking for an option to get the flat wire and do this ourselves currently. Regarding coil rock, the leads in the spider being stiffer due to heat will also create much more force on the spider itself than the leads being sewn onto the top of the spider at a few points. When sewn on top, the wires are still fully flexible and free to move as needed between these points with a minimal amount of force exerted on the spider. This is the best way to do it and many do the same. Look around and you'll find many car audio companies doing this. I saw a couple at bumpinbuick's place. The silicone may not look perfect, but it works well. Gluing a foam or felt pad underneath looks no better but many do this and I haven't heard complaints about all of them. In reality it is the bottom of the cone that nobody will see, so I don't understand what the real fuss is about. Yes, we have weighed how much we are adding. The silicone when dried adds about 3 grams to the the cone mass. This changes the total cone mass by about 1.25- 1.5% depending on the model. It has no real effect on anything. It is no different again than gluing the foam or felt to the bottom to protect against lead slap noise. How many drivers have failed exactly I do not know. It is not my job to keep track of every failure that others have. It is my job to address issues we have an prevent known issues. Woven in lead wires do tend to break and that is something I would like to stay clear of. I suggest calling companies like Kicker who have addressed the same issues, or companies like JL who state "The flying lead wires are carefully controlled and strain-relieved without resorting to woven-in lead wires, which can degrade spider performance." They both do not use woven in leads for obvious reasons. You could check with Eclipse and see how many of the TC made drivers had failed due to these issues over the period they were making them. Yes, we use 100% nomex spiders. If you want I can email you a copy of the sample ticket from Nuway and you could call them to verify what their NX3230 material is. John [/QUOTE]
