[QUOTE="Air, post: 831480, member: 15182"] Hi,It?s possible but not as straight forward as it might look. Phase will depend on how far the bass unit is from fullrange? The proposed inductor sounds about correct value but will have to be of very low DCR value, and you need to keep the series resistance in mind when calculating the ideal size and tuning of bass unit. Real challenge is to make sure proposed inductor sees a flat impedance curve. A LCR impedance correction is required in parrallel with driver with roughly the following values(18-25mh inductor, +/-220mfd and a 6-10ohm resistor) these values are purely thumb suck. Needs to be more accurately determined Do it with an active filter and biamp you might be better of. Safe a lot of big and expensive passive components and easier to get roll off and phase correct.
