    Yesterdays report.
    Built a temporary 1.4 cubic foot sub box out of MDF.
    Want to build a fiberglass box for the corner of the trunk, but my fiberglass skills need a lot of work and Im taking the car this weekend for a show.

    Also ran my first Dirac tune last night and Im really liking the results.
    There´s a learning curve for sure, but the quick tuning guide in this forum makes it a pretty straightforward job.

    First DIRAC tune.
    Followed the "Quick tuning guide" on DIYMA forum which made the process a lot easier.
    Horizontal lines are 10db scale.
    This is the tweeters graph.
    Left=Purple
    Right=Green.
    Corrected response under yellow solid line.
    Used a x-over at 1 khz pre-Dirac, but this tweeters can play pretty low.
    Have them playing from 3 khz and up with 24 dB LR high pass.

    Have them playing from 320 up to 3 khz and up with 24 dB LR on both ends.

    Im pretty impressed with the results you can get with the Mini DSP C8-12 DL and Dirac.
    In 20-30 minutes it left the car sounding pretty good and it still has a lot of potential.

    Took the car this weekend to the Monterrey Money Round event. 16 of the top cars in Mexico all vs all, no rules, 4 judges (including Richard Papasin and Ruperto Aguilar).


    The top 6 places where pretty close.
    1. 161.5
    2. 161.125
    3. 160.5
    4. 160.125
    5. 159.625
    6. 159. Me. (Just got the corrected results).

    Gave close to 50 demos with great feedback.
    Now its time to let the speakers break in before the next tune and keep working.

    Looking over the build thread, I missed to upload pics of two parts. Engine and kicks.
    Here´s the engine bay using OEM looking wire loom, bolts and electrical tape.

    The kicks where a bit more difficult mostly because of having to be in an awkward position.
    After moving the wiring harness, theres enough room in there for a 6.5" driver.

    Santa came a bit early this year.
    Been trying to get one from CSL for a couple of months with no luck and it seems they dont like to reply emails, so I ordered from Parts Express.
    Will play with both the Umik-1 and Umik-2, keep one and sell the other one.

    First measurements with the UMIK-2.
    Measured the response of my midranges with and without a dash mat.
    Showing the graph from 400 hz up to 20 kHz.
    Mids are playing 320-3200, but you can see how the dash mat also attenuates the tweeter frequencies and the tweeters isn't covered.
