Once the boxes were together and all the drivers were temporarily mounted, crossover work began. My friend, per my recommendation, had bought $250-300 in xo parts. When the preliminary xo was hooked up, we both thought ."dang, that doesn't sound so good". I didn't worry too much though, because I knew it'd be about 6 months before the crossover would be finalized. Since Thanksgiving, I've been working with Soundeasy v8.0 in my free time to get the crossover correct. I've had to learn how to use Soundeasy as well as figure out what we needed for crossover parts. Enter John K. I've known John existed for a while now, and only recently did I figure out he lived in Connecticut. Turns out he's 30 minutes away from me. After telling me about how I did half a dozen things wrong w/ the crossover, and then making some of his own modifications, the crossover is finalized. Here is the final frequency response.
