    It's Jeff Bagby's software "Passive Crossover Designer"

    OK, I've gotten my "production" parts assembled in the final XO design.

    This thing sounds great! I did an A/B compare today with the new passive XO on the right channel and the active XO on the left channel. Surprisingly, on the best mono recording I have (Nat King Cole After Midnight), the passive actually sounds just a tad bit better than the active. Woot. I consider that to be a smashing sonic success. The big 14 gauge perfect lay inductors in the HF section sound clearly better than the prototype inductors, and I replaced the 12 ohm resistor in the RLC notch filter with a pot so I can adjust the attenuation.

    Re: Rock the Garage!

    Just wanted to post a quick update on this.
    As some of you may have noticed, I upgraded the garage woofers with new GPA 416s. I also modified the crossovers to accommodate the differences in the woofers electrical behavior. After a few months of break-in, I have to say that the GPA 416s are phenomenal. Their sound is so full, so musical (its that lovely mid-bass sound), and clean. I may try to get a quick video with my HD camera and see if it can come close to conveying the awesomeness of the sound I enjoy in my garage...

    Re: Rock the Garage!

    I'm thinking of building the same crossover as I have some 802-8g's and a 416b. I've done the Z19's but want something simply for this project as they are out in the garage.

    Question, my LF is 8 ohm - your LF design is 16 ohm. What would I need to change on the LF circuit for this design to work on a 8 ohm LF 416?
