Using three woofers

rackmount · 8th November 2006, 12:55 PM

I would like to use three woofers per box in a project I am working on. They are all eight Ohm. two of them will go up to 5k and I would like to cut one off at 100Hz or so just to augment the low low end. My question is, how could I wire them so as they present a 6to 8 Ohm load the the amplifier and the other question is could some one help me with the cross over of 100Hz at about 12 Db per octive.
Any help would be appreciated.
Thank you

Crossing over that low will require a big inductor.

You can't get 8 ohm total load. You will have to wire the mids in series then those in parallel with the extra driver.
