I have 4 sets of 4 way passive crossover networks. Crossover points are at 100hz, 800hz, 5khz. The speakers this network is set up for are hartley tweeter, 4" near, 8" oaktron, 15" eminence speakers. These speakers are available for sale used as well. All you need to make your own speaker system. This is a high end set up. Quality parts sold for over $125 each. I would love for someone to get some use out of these. I will sell them for $25 each $100 for all 4. I don't always check my e-mail. You can reach me faster by phone 303-861-0328. Kirk
