Electronics III: Weeks 4 and 5

Before I left town I was able to start on the breadboard for the active crossover for my monitor. When I started I need to decide what type of active cross over I wanted to build and I chose the Sallen Key Low/High Pass filter. Then I needed to decide what my cutoff frequency would be in relation to the response of the tweeter and mid range driver I will be using. For that I used the Low Pass/High Pass Filter Design Tool from :

which uses the equation:

Fp = 1/ (2piRC) = Hz

I decided to send everything above 1326 Hz to the tweeter and everything below 1061 Hz to the midrange driver.

So here is my basic active crossover. I used the 5532 chip with 12k Resistors and 10nF Capacitors for my high pass filter. I then used 15k Resistors and 10nF Capacitors for low pass filter. For right now it has an Aux input for testing but will soon be connected to my audio amplifier that will send the signal to its respective speakers.

Here is the schematic I worked from:
