whats up easy, do u still want the EQX? i sent you a PM yesterday.. and to answer your question, i dont think any other company uses resistor modules as their crossover and SSF points.. you might want to make a new thread to get the answer to that question, though, im not absolutely sure about it. if you ever need a certain frequency module made i can do them for you for about 10 buccs each. or i can show u how to make them for 3 dollars each.. //content.invisioncic.com/y282845/emoticons/greedy.gif.5a53e6246569d7ab79867170f3b06629.gif thats if u ever get an audiocontrol or if you find an EQ besides audiocontrol that uses the resistors..
