Hello, I was searching for a replacement tweeter for my large Advents, and found this. I have a set of the new Large Advents, and the later 5012/w's. I'd like to have 4 speakers all the same (stackable), and replace the tweeters (especially the fried egg ones) with something better. I've got the woofers refoamed, and the cabinets of the 5012's braced. I plan on using fiberglass packing. just need a little more information about the crossovers. Would the crossover you listed Carl work well with the Dayton RS28F-4 tweeters, and the original woofers? If so, could you post a parts list including brands, and a good place to purchase them? Maybe, also a wiring diagram, so an electrical noob like me won't mess it up? I can solder though. Thanks for posting all this info, I'm pretty eager to hear what they're going to sound like. Dean
