    Well, didn't get the votes but had a good time and really hung in there compared with the other entries. In my subjective opinion, these have ended up with a really detailed and clean mid and high end. Perhaps a little forward, with just slightly softer bass that would still benefit from being closer to a wall.

    At this level of competition, really all the speakers sounded awesome. When everyone is targeting anechoic flat with good phase alignment, the differences become very subtle.

    Here's the final system response, thrown through Blender to add the close mic woofer and port sum. The slightly soft bass is caused by the slow downward slope under 200Hz, ending at 50 where F3 landed. I'm also guessing the perception of detail is due to the 5k-20k range landing toward the top of the +-3dB window. In my subjective opinion, these would be excellent near field monitors for mixing as they really highlight the details very well.

    And here's the final BOM and costs for the filter. I haven't done a simplified schematic yet, but the filter is textbook 2nd order on both with the padding resistor after the network to the tweeter.

      These were very cool. I have always loved the look of the old school coffins.
      Don't listen to me - I have not sold any $150,000 speakers.

        I thought they sounded excellent and were especially impressive in the bass given the 1/2 CF cabinet.

          Yes, they did sound good and you had some pretty stiff competition in your group too. You got my wife's vote for the best in your group.
