Yes actually they are Z19 crossovers an upgraded version of the original model 19 crossover designed by Zilch, everyone who has built them raves about them.... but that is probably using the 416 woofer so will have to see how they work with mine. Not sure how this will all match up. The altec horn driver is built for low power does not need high power to put out. My speakers including the woofer were built to go with the TFM55 amp I had back then and they love power, lots of power, the more power you put to them the happier they are..... but with my aging ears the bullet tweeters I have in them now just is not cutting itLooking good Ray,
So you decided to go with the M19 instead of the 1209 network ?
