[sdiy] Speaker Impedance

[Tim Parkhurst]

Hey Rafael,

If memory serves (sometimes it does, sometimes it don't...), I believe the
same tricks used with resistors will work with speakers. Ohm's Law still
applies. In other words, two 16 Ohm speakers wired in parallel will give you
8 Ohms. Conversely, two 16 Ohm speakers wired in series will give you 32
Ohms, and so on.
