what ohms would I have?


if i am building a center channel with the follow speakers:

2 woofers 4 ohms each
1 mid 4 ohm
1 tweeter 6 ohm

if i run them off of the following 3 way crossover what is the correct way to hook it up? series for the woofer or parallel?

This network is an excellent choice for high power 3-way systems. The woofer section rolls off 6 dB at 800 Hz while the tweeter section uses a 12 dB per octave roll off at 4,500 Hz. The midrange section uses a true band pass filter with a response of 750-5,000 Hz. 12 dB per octave roll off. All crossover frequencies are rated into a 8 ohm load.

Duke is absolutely correct. The impedances that the crossover components see(inductors/capacitors) determine at what frequency they begin their rolloff. Also- If you were to parallel the woofers: the resultant impedance would probably drop below 2 ohms at some frequencies(could cause amp problems). Some good info here: (http://sound.westhost.com/lr-passive.htm) 20 some years ago, this guy used to wind some very nice custom inductors for my business, and he still sells individual components(see right side of page): (http://www.madisound.com/services/hifispeakerdesign.php)
You could get away with the tweeter, and an 8 ohm mid, but the response(you'd have a hole) would be far from optimum. Then too: did you make certain the efficiency of the purchased drivers matched? As Mr T suggested: getting a kit from someone like Madisound would be the hot setup. I'll bet he could cook something good up, for your application.
