What is the impedance load when wiring 16-ohm speakers in parallel?

When wiring multiple resistive loads like speakers in parallel, the total impedance can be calculated using the formula for parallel resistances. For speakers, the total impedance (Z_total) can be derived from the formula:

1/Z_total = 1/Z1 + 1/Z2 + 1/Z3 + ... + 1/Zn

In this case, if you have multiple 16-ohm speakers, and you wire two of them in parallel, you can calculate it as follows:

1/Z_total = 1/16 + 1/16

This simplifies to:

1/Z_total = 2/16 = 1/8

Rearranging that gives you Z_total = 8 Ohms.

If you were to add more 16-ohm speakers in parallel, the total impedance would continue to decrease. Therefore, in this scenario, wiring two 16-ohm speakers in parallel results in a total impedance of 8 Ohms. This aligns perfectly with the choice of 8 Ohms being the correct answer in this case.
