The product over the sum formula only works for two parallel resistances. The more advanced form of the formula is 1 / ( (1/R1) + (1/R2) + (1/R3) + (1/R4) + ... ) and so forth.
To answer your question plug in the voice coil values for R
1 / (1/3) + (1/3) + (1/3)...
1 / .9999999
= 1 ohm
Another example, MTX sells 12 ohm subs, plug in 12 for R1, R2 and R3 and you end up with a 4 Ohm load
