Someone asked about crossover information. I made my own for a 3-way system that I use. The design information was obtained from a book called "The Recording and Reproduction of Sound" which was published by Howard Sams in 1952. The information is basic high and low pass filter design. The type of network I use basically has two components for each speaker: series L and shunt C for the woofer and series C and shunt L for the tweeter. For the mid range speaker I used a combination hi/lo pass. The crossover frequencies I used were 500 Hz and 3 kHz. The big problem was finding the large capacitors necessary for the low frequency. In my case, two 23 uf caps were needed. I finally lucked out and found some fairly large mylar caps I could parallel to get the 23 uf. I do not like using back-to-back electrolytics! Bob Roehrig
