Need speakers that can rock with just one watt? You found da place.

RE: Can I wind an optimized x-former for my needs?


This is a perfect example of what I was saying. Here is the simulation of your crossover by simply replacing a 4dB pad with a 4dB autoformer.





The underdamped LC resonance gives a 4 dB bump at the crossover frequency which will definitely change the sound. Simply changing the value of the shunt resistor from 1E99 to 13 brings the response back to match the L-pad situation. (1E99 is a simple way to take the shunt resistor out of circuit) In the sim below you can see the autoformer response wiht and wihtout the shunt resistor compared to the L-pad.





The LT spice file is at the link below. Simply download LTspice and run it to get playing.
