Hi Dbphd,
Sounds messy.
Parallel impedance divides. When speaker makers do this, the crossovers prevent impedance dividing. That is, the tweet, midrange and woofer don't seem to be in parallel to the amplifier's sense of impedance (more or less).
Without that, the basic resistance formula is like this R = 1 / ( 1/Ra + 1/Rb ...) so, roughly:
R = 1 / ( 1/4 + 1/8 ) = 2.7 Ohms.
A pretty low value.
Also, there is no level matching. Again, something crossover designers do for you. The level of one speaker may be far different than another.
So, in general, I'd say no, don't do this. If you were going to use a pair for say, one pair in your pool, another in your bedroom, this approach would be OK if the resulting impedance was high enough.
What you really want to do in this case is use an active crossover, and separate amps for each speaker.
Best,
E
