I'm trying to piece together a DIY component set that will work well with my amp (2 channel Xtant: 50W each @4ohms, 100W each @2ohms)
I read that if you pair a 4 ohm tweet with a 4 ohm mid in paralalle with a crossover, the total impedance to the amp will still be 4 ohms (not 2 like I would expect), because as you move into the blocked frequencies on a crossover the impedence rises towards infinity and effectivly removes the speaker from the circuit.
What I'm trying to figure out is how much power will make it to each speaker. I'm starting to think that with a 4ohm tweet and a 4ohm mid 50W will go to each speaker, with the amp seeing a load of 4ohms... Is this right?
Can somebody help me out? A yes or no answer will work, but if somebody wants to take the time to explain the how and whys, that would be awesome Posts: 45 | From: Richmond, VA | Registered: Apr 2004

You are correct about the impedance, and the reasoning behind it.
As for how much power each driver gets, wel lit depends on the frequencies being played. If you have a 100 watt sine wave at 100Hz, your mid will get 100 watts (minus some loss in the croosover). With music it would be split, but still depend on the frequencies, since there is more power in the lower frequencies, your mid will get more power than the tweets.
