L Pad question - series drivers

Hey guys - was wondering if I could get a (hopefully!) quick question answered.

I am looking at L pad tutorials and calculators and they all assume you have a single driver behind the L pad. If I am designing an L pad for a mid range section that has two 8 ohm drivers in series behind it, I am assuming that I would be impedance matching in the equations/calculators to 16 ohms, correct? Thanks!
