I have 2 pairs of 4-ohm bass drivers. I plan to build a pair of floor-standing enclosure with a pair of the woofers per cabinet. The problem is if I’m gonna safe the amp I have to wire the woofers in series to bring an impedance to 8 ohms. But the inductor values for a crossover is going too high. Said if the crossover point is below 200Hz, the inductor for a simple second-order filter will be exceeded 10mH. So, can I do like this? If I’m going to add a resistor in parallel with the series wiring woofers, in order to half the impedance to 4 ohms. Does anyone has experience with this? What is the result? Thank you in advance.
