If I use 2 woofers with this crossover that was desogned for 1 what changes should I make?

I'm no pro so take what I say with a grain of salt or two.

I think you would have to change the values for the new impedance on the low pass.

You may have to change the Lpad on the tweeter to increase the efficiency, but I am not sure by how much.

Also, you may have to make other adjustments for dispersion reasons. For example, the three drivers will be producing the same frequencies at the same time with different distances between the drivers. This may cause lobing or comb filtering but I dunno. Just giving you some ideas.

Just trying to help, so if I have steered you wrong someone will come along and deliver a beat down.

Looks like it has an Lpad on the tweeter. You probably want to take it off as the sensitivity of the woofers will increase 3db.
